3 Description

The TPS60151 is a switched capacitor voltage

converter which produces a regulated, low noise, and

low-ripple output voltage of 5 V from an unregulated

input voltage. It maintains 5-V regulation even when

VIN is greater than 5 V.

The 5-V output can supply a minimum of 140-mA

current.

The TPS60151 has built-in current limit and output

reverse current protection that are ideal for HDMI,

USB OTG and other battery powered applications.

TPS60151 operates in skip mode when the load

current falls below 8 mA under typical condition. In

skip mode operation, quiescent current is reduced to

90 μA.

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 operates over a free air temperature

range of –40°C to 85°C. The device is available with

a small 2-mm × 2-mm 6-pin SON package (QFN).
