Overview

This xCHIP is based on the FAN5702 PWM controller, a configurable LED driver with I²C control. The device can drive up to 4 channels at 4 A each using IRLML2502 MOSFETs to provide control over RGBW strip lighting. The xCHIP also features a TS30011 synchronous buck convertor which offer wide DC input range power supply for powering the system and connected xCHIPS.

The TS30013 is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The TS30013 utilizes current mode feedback in normal regulation PWM mode. When the regulator is placed in standby, the device draws less than 10uA quiescent current. The TS30013 integrates a wide range of protection circuitry including input supply under-voltage lockout, output voltage soft start, current limit, and thermal shutdown.
