The RT9378 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 RT9378 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 RT9378 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.资料下载
