W-5200-5
Low Noise Regulated
Charge Pump DC-DC Converter
Description
The:ïareswitchedcapacitorboostconvertersthatdeliver
alownoise,regulatedoutputvoltage.
W-520ïgivesafixedregulated5Voutput.
 The constant frequency 2 MHz charge pump allows small 1ȝF
ceramic capacitorsto 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 batteryïpowered applications.
A shutdown control input allows the device to be placed in
powerïd own mode, reducing the supply current to less than ȝ$.
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 powerïup.
