Description

The PAM2810 provides 4 regulated current sinks, capable of sinking up to 40mA current to accommodate 4 white °Cs. It requires no charge pump, has no noise and EMI, and significantly improves the efficiency in Li bettery range. °C brightness can be control°C 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 °C. The device is in shut down mode when the EN input is logic low. The PAM2810 is available in SOT23-8 and DFN2mmx2mm packages.
