TPS55340PWPR Description

The TPS55340PWPR is a monolithic, nonsynchronous, switching regulator with an integrated 5-A, 40-V power switch. The TPS55340PWPR can be configured in several standard switching-regulator topologies, including boost, SEPIC, and isolated flyback. The regulator TPS55340PWPR 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.
