The TPS54527 enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54527 uses the D-CAP2 mode control which provides a fast transient response with no external compensation components. The TPS54527 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, ...
