RP1364A - RICHPOWER

RP1364A 4 Channels 100mA x1/x1.5/x2 Charge Pump White LED Driver

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 charg.
