RT9378AGQW Product Details

The RT9378AGQW is a 4 CH WLED driver with auto mode selection of x1, x1.5 and x2 mode with low dropout voltage in current sources. The RT9378AGQW can power up to 4 white LEDs with regulated constant current for uniform intensity. Each channel (LED1 to LED4) can support up to 25mA. The part maintains highest efficiency by utilizing x1/x1.5/x2 fractional charge pump and low dropout current regulators. For the brightness control, user can easily use a PWM signal generated from GPIO to control the brightness of WLEDs. The RT9378AGQW is available in a WQFN-12L 2x2 package. Small 0.22μF capacitors can be used for fly capacitors. It provides the best backlighting solution with high efficiency and smallest board space for portable application.
