® RT9379 6 Channels 150mA x1/x1.5/x2 Charge Pump White LED Driver General Description The RT9379 is a 6 channel WLED driver with auto mode selection of x1, x1.5 and x2 mode with low dropout voltage in current sources. The RT9379 can power up to 6 white LEDs with regulated constant current for uniform intensity. Each channel (LED1 to LED6) 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 RT9379 is available in a WQFN-16L 2x3 package. Small 1μF capacitors can be used for fly capacitors.
