Introduction

AI Translation

The TPS54340 is a 42V, 3.5A step-down regulator with an integrated high-side MOSFET. Per ISO 7637, the device can withstand load dump pulses up to 45V. Current mode control provides simple external compensation and flexible component selection. A low-ripple pulse skip mode reduces no-load supply current to 146μA. When the enable pin is pulled low, shutdown supply current is reduced to 1μA.
