Description

General part information

TPS54428 Series

The TPS54428 is an adaptive on-time D-CAP2™ mode synchronous buck converter.

The TPS54428 enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution.

The main control loop for the TPS54428 uses the D-CAP2™ mode control that provides a fast transient response with no external compensation components.
