Overview
Preliminary RP1365 4 Channels 100mA x1/x1.
5/x2 Charge Pump White LED Driver General Description The RP1365 is a 4 channel WLED driver with auto mode selection of x1, x1.
5 and x2 mode with low dropout voltage in current sources.
The RP1365 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 RP1365 is available in a WQFN-16L 3x3 package.
Small 0.
22uF capacitors can be used for fly capacitors.
It provides the best backlighting solution with high efficiency and smallest board space for portable application.
