CAT3200HU2_14 Datasheet, PDF (1/9 Pages) ON Semiconductor – Low Noise Regulated Charge Pump DC-DC Converter

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.
