General Description The RT9362/A is a high efficiency charge pump white LED driver. It supports up to 4 white LEDs with regulated constant current for uniform intensity. The RT9362/A maintains the highest efficiency by utilizing a x1/x1.5/x2 fractional charge pump and low dropout current regulators. User can easily configure each LED current up 30mA by an external resistor. Two digital inputs can be programmable to control white LED On/Off. LED dimming can be achieved by applying a PWM signal to the digital control signals. w w w .D a t a e h S et 4U .
