RT4531 Datasheet | Richtek

Reference Sample & Design Buy ® Dual Channel 10s2p WLED Drivers General Description The RT4531 is a dual-channel current source with highefficiency asynchronous boost converter for backlight application. The RT4531 has built-in 1.5A/36V power MOSFET and two high current-matching capability current sink, so RT4531 can drives up 10s2p white LED. The RT4531 can allow very low voltage headroom control, therefore to improve LED strings efficiency effectively. The RT4531 supports both PWM dimming and 1-wire digital dimming interface and it can realize 10 bit brightness code programming. The RT4531 provides plete protection functions such as input Under-Voltage Lockout (UVLO),...
