TPS54240-Q1 - DC-DC Converter

Description

The TPS54240-Q1 device is a 42-V, 2.5-A, stepdown regulator with an integrated high-side MOSFET.

Current-mode control provides simple external compensation and flexible component selection.

A low-ripple pulse-skip mode reduces the no-load, regulated-output supply current to 138 μA.
