KTD3133, KTD3134, KTD3136 and KTD3137: New LED Backlight Driver and Flash Portfolio

San Jose, Calif. – August 30, 2018 – The demand for advanced LCD Panel lighting solutions that deliver increased capabilities in a small package continues to grow. That’s why power management leader Kinetic Technologies is pleased to announce the launch of KTD3133, KTD3134, KTD3136 and KTD3137 (KTD3133/4/6/7), the latest 2- and 3-channel solutions in its LED backlight driver IC portfolio.

KTD3133/4/6/7 provide LED backlighting for LCD displays up to seven inches. KTD3137 and KTD3134 include a high current mode that drives the panel LEDs brighter during front side camera, still and video capture. Both backlight and flash modes operate using a single inductor, which drastically reduces the PCB area and eliminates components. These highly integrated step-up DC-DC converters operate with an input voltage from 2.7V to 5.5V and accommodate 1-cell lithium ion batteries or 5V supply.

“We’re thrilled to offer leading edge architectures to our customers to improve their product functionality,” says Kinetic Technologies Vice President David Nam. “We’re committed to driving solutions that predict the needs of OEMs, and this new LED backlight and flash family of solutions helps manufacturers decrease PCB area, reduce component count and improve the user experience.”

Each of the current sinks in the KTD3133/4/6/7 can regulate up to 30mA in backlight mode and are equipped with I²C interface for various controls. KTD3134/7 can drive up to 60mA in panel flash mode. Built-in protection features include: cycle-by-cycle inductor current limit, output overvoltage, LED fault (open or short) and thermal shutdown.

KTD3133/4/6/7 are available in a RoHS compliant 12-ball 1.19mm x 1.64mm WLCSP. Key applications include smartphones and tablets.

KTD3133/4/6/7 is available and shipping now. Visit Kinetic Technologies for more information.

San Jose, Calif.  April 19, 2018   Power management leader Kinetic Technologies announced today the launch of USB Type-C Port Protector KTU1101, an important milestone for USB data line protection, and a significant addition to the company’s extensive overvoltage protection (OVP) portfolio. Now designers can avoid risk with this new, ultra-fast technology that offers an OVP response time of 15 nanoseconds (ns) beating the industry by a large margin.

Our goal is to raise the bar across OVP technology, and the KTU1101 does just that,” says Kinetic Technologies Vice President David Nam. “This level of protection for USB Type-C ports is an industry first. Competitive solutions are more than 350% slower to respond, which results in risk of system failure during short-to-VBUS events.” He continues, “this is a superior OVP solution that meets the demands of major OEMs, including the ability to truly protect down-stream ICs with a 6V absolute maximum ratingno one else is doing this.”

The KTU1101 provides ESD, surge, and OVP for USB Type-C CC/VCONN and SBU signal lines. Physical or moisture-related shorts between the signal pins and VBUS at elevated PD voltage levels can cause catastrophic damage to internal electronics; KTU1101 avoids the risk by keeping internal data line voltages below 6V. Integrated ESD protection eliminates the need for external TVS diodes.

The KTU1101’s ultra-fast response time and small solution size make it an ideal solution for USB Type-C port protection across many applications, including mobile and computing devices like smartphones, tablets and computers, as well as industrial hardware and enterprise solutions.

The KTU1101 is packaged in RoHS and green compliant 1.7mm x 2.1mm wafer-level chip-scale packaging and samples are available today. Contact Kinetic Technologies for more information.

San Jose, Calif.  January 23, 2018   Power management leader, Kinetic Technologies, announced today the launch of the KTS1612, a two input, two output push-button reset IC with dual discharge paths and extremely low quiescent current in a tiny 1.5mm x 2.0mm UQFN package.

The KTS1612 operates over the 2.2 V to 5.5V supply voltage range, consuming less than 500nA (typ) of supply current at 4V, 80 percent lower than competing solutions, extending battery run time. This new solution generates a reset pulse for a factory-programmed reset timeout period after both manual reset inputs have been held logic-low for the factory-programmed setup period. The IC controls an optional external MOSFET, which is used to disconnect the battery from the system during shipping mode and system reset mode. The KTS1612’s dual discharge paths can power-cycle the system bus voltage and battery path during system reset unlike any industry solution of its kind.

“System designers face multiple problems with non-removable batteries,” says Erik Ogren, senior director of mobile in the Kinetic Technologies marketing group. “Battery discharge during shipping can create a poor experience when the user first attempts to power up their new device. Another problem affecting the user experience is when the operating system hangs, requiring a hardware reset, which is difficult to implement without a dedicated reset button. This solution solves both of these problems, and in a tiny package.”

The KTS1612 is available in Pb-free, fully green compliant, small 10-pin UQFN 2.0mm x 1.5mm package. Key applications include smartphones and tablets, wearables, portables, digital still cameras, video cameras, remote controls, Bluetooth speakers and GPS.

KTS1612 is available and shipping now.Visit Kinetic Technologies for more information about the KTS1612.

Product features include:

• Operating Range: 2.2V-5.5V
• Supply Current: 500nA _typ (V_DD = 4V)
• Controls external MOSFET disconnect switch
• Shipping mode disconnects embedded battery
• Two pushbutton inputs, two reset logic outputs
• Two pins to independently discharge two system voltages during reset
• Low Quiescent Current: Max 1A in shipping mode

San Jose, Calif. January 5, 2017 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the AS1114, a single chip, highly integrated power solution targeted at 13W PoE, Powered Devices, requiring high efficiency and small size.  The AS1114 is specifically designed to fully support IEEE Std. 802.3at Type 1 PDs, and enables customers to bring to market higher performance products including VoIP phones, IP security cameras and wireless LAN access points. The innovative silicon solution, built on standard HV CMOS technology, includes system-level circuitry for lower EMI emissions and robust surge protection, in addition to the PD controller functionality.

The AS1114 combines rectification and protection circuitry with a PD controller and a DC-DC controller. This high level of integration provides significant reliability and protection advantages, as well as simplifying the PoE PD design. The device provides seamless support for local power and over temperature protection.

The AS1114 also provides advanced power management through integration of a hot-swap switch and a DC-DC controller that operates from a switched input voltage and includes soft-start and current limiting functions. The DC-DC architecture is a current mode converter, which can be configured with external component changes for either fly-backor buck topologies to support non-isolated or isolated switching topologies.  The device is designed to provide a safe low impedance discharge paths directly back to the earth ground, resulting in superior reliability and circuit protection.

The AS1114 includes a series of platform tested circuit capabilities to assist system designers in providing solutions that meet or exceed the current regulatory and extreme environmental usages.

The AS1114 is a highly integrated PD product that addresses the needs of the high growth PoE market,” said Fred Greenfeld, Applications Director at Kinetic Technologies. A key requirement of PoE systems is immunity to overvoltage and surge events. The AS1114 is unique in addressing EMI and surge resilience, and by integrating the diode bridge and protection circuitry, it significantly increases the reaction time of protection devices and PHY immunity to over-voltage stress events. Integrating these components also substantially reduces board-to-board variation and increases overall manufacturability, providing the customer with time to market advantage, while saving overall system cost and maximizing system efficiency.”

The AS1114 is supplied in a QFN55-20, RoHS and Green Compliant package and is rated over the -40 degree C to +85 degree C industrial temperature range.
