SLVS887C – APRIL 2009 – REVISED AUGUST 2014 TPS53114 Single Synchronous Step-down Controller for Low Voltage Power Rails
1 Features 3 Description The TPS53114 is a single, adaptive on-time DCAP2в„ў mode synchronous buck controller. The
TPS53114 enables system designers to complete the
suite of various end equipment's power bus
regulators with cost effective low external component
count and low standby current solution. The main
control loop for the TPS53114 uses the D-CAP2в„ў
mode control which provides a very fast transient
response with no external components. The
TPS53114 also has a circuit that enables the device
to adapt to both low equivalent series resistance
(ESR) output capacitors such as POSCAP or SPCAP and ultra-low ESR ceramic capacitors. The
device provides convenient and efficient operation
with input voltages from 4.5 V to 24 V and output
voltage from 0.76 V to 5.5 V. 1 D-CAP2в„ў Mode Control
