1.5 A Step-Down Buck Switching Regulator IC TPS54140GGQR

Description

The TPS54140 series is a DC-DC step-down (buck) switching regulator IC designed for efficient conversion of higher input voltages down to a stable lower output voltage. It integrates a high-side MOSFET and supports adjustable output voltage with current-mode control. The device is available in a 10-pin HVSSOP/MSOP package suitable for surface-mount PCB applications.
