1 Features 3 Description The TPS53125 is a dual, adaptive on-time D-CAP2в„ў
mode synchronous buck controller. The part enables
system designers to cost effectively complete the
suite of various end equipment's power bus
regulators with a low external component count and
low standby consumption. The main control loop for
the TPS53125 uses the D-CAPв„ў Mode topology
which provides a very fast transient response with no
external component. 1 D-CAP2в„ў Mode Control
