Description

The TPS60255 is a high-efficiency, constant frequency charge pump DC/DC converter that uses 1× and 1.5× conversion to maximize efficiency for the input voltage range. By using adaptive 1×/1.5× charge-pump modes and very low dropout current regulators, the TPS60255 achieves high efficiency for the entire one-cell lithium battery range. The protection features include soft start, over-current limit, thermal shut down, and over-voltage detection. The device automatically detects and removes unused current sinks from the control loop.

This device drives six 25 mA current sinks and one 80 mA current sink. These current regulators are programmed by three independent brightness registers and five ON/OFF bits using a single-wire interface (EasyScale™). This offers flexible applications for a variety of lighting control in portable devices.
