TPS5401 Datasheet (Texas Instruments)

TPS5401, Step-Down Converter

The TPS5401 device is a 42-V, 0.5-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 supply current to 116 μA when outputting regulated voltage with no load.
