SLVSB01D – OCTOBER 2011 – REVISED AUGUST 2016 TPS54295 2-A Dual Channel Synchronous Step-Down Switcher With Integrated FET
1 Features 3 Description The TPS54295 is a dual, adaptive on-time D-CAP2
mode synchronous buck converter. The TPS54295
enables system designers to complete the suite of
various end-equipment power bus regulators with a
cost effective, low component count, and low standby
current solution. The main control loops of the
TPS54295 use the D-CAP2 mode control which
provides a very fast transient response with no
external compensation components. The adaptive ontime control supports seamless transition between
PWM mode at higher load conditions and Eco-mode
operation at light loads. Eco-mode allows the
TPS54295 to maintain high efficiency during lighter
load conditions. The TPS54295 is able to adapt to
both low equivalent series resistance (ESR) output
capacitors such as POSCAP or SP-CAP, and ultralow ESR ceramic capacitors. The device provides
convenient and efficient operation with input voltages …
