Description
KTE7200 is a robust single chip wireless power receiver optimized for low cost, low component count, and low cost PCB designs. This device is optimized for small low power devices with small coils, while also being capable of as much as 5 watts of output with an appropriate thermal design.
This is a microcontroller based design, optionally configurable by OTP memory, resistor programming features, and/or control via the I2C interface.
KTE7200 is highly integrated including 8k ROM, 8k OTP memory, an LDO regulator with OVP/OCP/RCP, and precision regulated DC output.
