TPS60151 采用 2x2 QFN 封装的 140mA、5V 充电泵

TPS60151 描述

The TPS60151 is a switched capacitor voltage converter which produces a regulated, low noise, and low-ripple output voltage (5V) from an unregulated input voltage. It maintains 5V regulation even when VIN is greater than 5V.

The 5V output can supply a minimum of 140mA current with a small 2X2 QFN package.

TPS60151 operates in skip mode when the load current falls below 8mA under typical condition. In skip mode operation, quiescent current is reduced to 90µA.

Only 3 external capacitors are needed to generate the output voltage, thereby saving PCB space.

Inrush current is limited by the soft start function during power on and power transient states.

The TPS60151 has built-in current limit and output reverse current protection that are ideal for HDMI, USB OTG and other battery powered applications
