Preliminary
RP1364A
4 Channels 100mA x1/x1.5/x2 Charge Pump White LED Driver
General Description
The RP1364A 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 RP1364A 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. An internal 5-bit DAC is used for brightness
control. Users can easily configure up to 16-step of LED
current by enable pin.
The RP1364A 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.
