TPS54340 Datasheet PDF – Step Down DC-DC Converter

Part Number: TPS54340

Function: 42 V Input, 3.5 A, Step Down DC-DC Converter with Eco-mode

Package: HSOIC 8 Pin Type

Manufacturer: Texas Instruments


TPS54340 datasheet



The TPS54340 is a 42 V, 3.5 A, step down regulator with an integrated high side MOSFET. The device survives load dump pulses up to 45 V per ISO 7637.

Current mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load supply current to 146 μA. Shutdown supply current is reduced to 1 μA when the enable pin is pulled low.


1. 4.5 V to 42 V (45 V Abs Max) Input Range
