Introduction

AI Translation

The TPS54561-Q1 is a 60V, 5A step-down regulator with an integrated high-side MOSFET. The device withstands load dump pulses up to 65V per the ISO 7637 standard. Current mode control provides simple external compensation and flexible component selection. Low-ripple pulse skip mode and 152μA supply current enable high efficiency under light load conditions. Pulling the enable pin low reduces shutdown supply current to 2μA. The UVLO is internally set to 4.3V. This threshold can be increased using an external resistive voltage divider on the enable (EN) pin. The soft-start pin controls output voltage ramp-up and can also be configured for sequencing or tracking. An open-drain power-good signal indicates the output is within 93% to 106% of its nominal voltage. The wide-range adjustable switching frequency allows optimization for efficiency or external component size. Cycle-by-cycle current limiting, frequency foldback, and thermal shutdown protect the device under overload conditions. The TPS54561-Q1 is available in a 10-pin, 4mm x 4mm WSON package.
