W-5200/

W-5200-5

Low Noise Regulated

Charge Pump DC-DC Converter

Description

The

are switched capacitor boost converters that deliver

a low noise, regulated output voltage.

W-520

gives a fixed regulated 5 V output.

The constant frequency 2 MHz charge pump allows small 1 F

ceramic capacitors to be used.

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

wide range of input supply voltages (2.7 V to 4.5 V) making the device

ideal for battery powered applications.

A shutdown control input allows the device to be placed in

power d own mode, reducing the supply current to less than

.

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

is a

1 mm max thin SOT23 package.
