Design TPS54228
SLVSAU1E – MAY 2011 – REVISED AUGUST 2016 TPS54228 4.5-V to 18-V Input, 2-A Synchronous Step-Down Converter With Eco-Mode™
1 Features 3 Description The TPS54228 device is an adaptive on-time DCAP2в„ў mode synchronous buck converter. The
TPS54228 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 TPS54228 uses the D-CAP2в„ў mode control that
provides a fast transient response with no external
compensation components. The adaptive on-time
control supports seamless transition between PWM
mode at higher load conditions and Eco-Modeв„ў
operation at light loads. Eco-Modeв„ў allows the
TPS54228 to maintain high efficiency during lighter
load conditions. The TPS54228 also has a proprietary
circuit that enables the device to adopt to both low
equivalent series resistance (ESR) output capacitors, …
