TPS57140-Q1 - Step-Down DC-DC Converter

Description

The TPS57140-Q1 device is a 42-V, 1.5-A step-down 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 116 μA.
