Product Summary

The TPS60255RTER is a high-efficiency, constant frequency charge pump DC/DC converter that uses 1x and 1.5x conversion to maximize efficiency for the input voltage range. By using adaptive 1x/1.5x charge-pump modes and very low dropout current regulators, The TPS60255RTER 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 TPS60255RTER automatically detects and removes unused current sinks from the control loop. The applications of the TPS60255RTER include Cellular Phones, Portable Navigation Displays, and Multi-display Handheld Devices.
