SLVSBD4C – MAY 2012 – REVISED JANUARY 2015 TPS55340 Integrated 5-A Wide Input Range Boost/SEPIC/Flyback DC-DC Regulator
1 Features 3 Description The TPS55340 is a monolithic, nonsynchronous,
switching regulator with integrated 5-A, 40-V power
switch. The device can be configured in several
standard switching-regulator topologies, including
boost, SEPIC, and isolated flyback. The device has a
wide input voltage range to support applications with
input voltage from multicell batteries or regulated
3.3-V, 5-V, 12-V, and 24-V power rails. 1 Internal 5-A, 40-V Low-Side MOSFET Switch
