The RT9287A is an integrated solution for WLED and camera power. It contains a boost converter with internal schottky diode to provide WLED power and Dual LDO for the power of camera image sensor. In the section of boost converter, RT9287A's optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. Internal soft start function can reduce the inrush current. The initial current of WLED is set by the external resistor RSET. The feedback voltage is 250mV. In the section of DLDO, RT9287A is a dual channel, low noise, and low dropout regulator sourcing up to 300mA at each channel. The part offers 2% accuracy, low dropout voltage (240mV@300mA), and low ground current, only 27A per LDO. The shutdown current is near zero current, which is suitable for battery-power devices. Other features include current limiting, over temperature, output short circuit protection. The part is short circuit thermal folded back protected. RT9287A lowers its OTP trip point from 165C to 110C when output short circuit occurs (VOUT < 0.4V) providing maximum safety to end users. RT9287A is available in a WDFN-12L 3x3 package.
