Product introduction

TPS54140-Q1 具有 Eco-Mode 的 3.5V 至 42V 输入、1.5A 降压转换器

illustrate

该TPS54140器件42V的1.5A的，下台与集成高侧MOSFET的稳压器。 Current mode control provides simple external compensation and flexible component selection. A low ripple, pulse-skipping mode reduces no-load and regulates 116μA of output supply current. 使用Enable引脚，关断电源电流降至1.3μA。

Undervoltage lockout is internally set to 2.5V, but an enable pin can be added. The output voltage-start ramp controls the slow-start pin, which can also be used in sequencing/tracking configurations. Open-drain power supplies output a good signal indicating a voltage rating of 93% to 107%.

The wide switching frequency range allows efficiency and external component size to be optimized.
