CAT3200HU2

Low Noise Regulated

Charge Pump DC-DC

Converter

Description

The CAT3200HU2 is a switched capacitor boost converter that

delivers a low noise, regulated output voltage. The CAT3200HU2

gives a fixed regulated 5 V output when the FB pin is tied to ground,

otherwise it provides an adjustable output using external resistors. The

constant frequency 2 MHz charge pump allows small 1

mF ceramic

capacitors to be used.

Maximum output loads of up to 100 mA can be supported over a

wide range of input supply voltages making the device ideal for

battery−powered applications.

A shutdown control input allows the device to be placed in

power−down mode, reducing the supply current to less than 1

mA.

In the event of short circuit or overload conditions, the device is

fully protected by both foldback current limiting and thermal overload

detection. In addition, a soft start, slew rate control circuit limits inrush

current during power−up.

The CAT3200HU2 is available in the tiny 8−pad UDFN

2 mm x 2 mm package.
