Description
General part information
TPS56637 Series
The TPS56637 is a high efficiency, high-voltage input, easy-to-use synchronous buck converter with integrated MOSFETs.
With the wide operating input voltage range of 4.5 V to 28 V, the TPS56637 is ideally suited for systems powered from 12-V, 19-V, 24-V power-bus rails. It supports up to 6-A continuous output current at output voltages between 0.6 V and 13 V.
The TPS56637 uses DCAP3™ control mode to provide fast transient response, good line and load regulation, no requirement for external compensation, and supports low equivalent series resistance (ESR) output capacitors such as POSCAP and MLCC.
