DESCRIPTION
●The TPS542941 is a dual, adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS542941 enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, and low standby current solution. The main control loops of the TPS542941 use the D-CAP2™ mode control which provides a very fast transient response with no external compensation components.
