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.

The operating voltage range is 2.5V to 5.5V. Internal softstart circuitry effectively reduces the in-rush current both while start-up and mode change. RT9362/A also provides comprehensive protections such short circuit protection and over-temperature protection. The load is disconnected from VIN while shutdown and the shutdown current is less than 1uA. RT9362/A is available in a QFN-16L 3x3 package.
