TPS54329EDDAR

3A 同步降压转换器

DESCRIPON

The TPS54329E is an adaptive on-time D-CAP2™ mode synchronous buck converter. The TPS54329E

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

TPS54329E uses the D-CAP2™ mode control that provides a fast transient response with no external

compensation components. The adaptive on-time
