General Description

The TPS54140A 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.

Key Features

1 3.5-V to 42-V Input Voltage Range.
200-mΩ High-Side MOSFET.
High Efficiency at Light Loads with a Pulse Skipping Eco-mode™.
Tighter Enable Threshold than TPS54140 for More Accurate UVLO Voltage.
Adjustable UVLO Voltage and Hysteresis.
116-μA Operating Quiescent Current.
1.3-μA Shutdown Current.
100-kHz to 2.5-MHz Switching Frequency.
Synchronizes to External Clock.
Adjustable Slow Start/Sequencing.
