TPS54140 Datasheet (Texas Instruments) - 42-V Step-Down DC-DC Converter

TPS54140, 42-V Step-Down DC-DC Converter

The TPS54140 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.
