RT9373A - 3-Channel Charge Pump White LED Driver

Features

  • The RT9373A is a high efficiency and cost effective charge pump white LED driver. It supports up to 3 white LEDs with regulated constant current for uniform intensity. The RT9373A maintains the highest efficiency by utilizing a x1/x1.5/x2 charge pump and low dropout current regulators. User can easily configure each LED current from 1.25mA to 20mA by a pulse dimming control. The dimming of white LEDs current can be achieved by applying a pulse signal to the EN pin. There are totally 16 steps of.
