The PAM2810 provides 4 regulated current sinks, capable of sinking up to 40mA current to accommodate 4 white LEDs. It requires no charge pump, has no noise and EMI, and significantly improves the efficiency in Li bettery range.
LED brightness can be controlled by PWM techniques. The constant current sink is set with an external sense resistor.
Alternatively, a PWM signal applied to the EN pin can vary the anticipated brightness of the LED. The device is in shut down mode when the EN input is logic low.
The PAM2810 is available in SOT23-8 and DFN2mmx2mm packages
