TPS60255 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.
