CAT3200, CAT3200-5
Low Noise Regulated Charge Pump DC-DC Converter
FEATURES
APPLICATIONS
The CAT3200 and CAT3200-5 are switched capacitor
boost converters that deliver a low noise, regulated
output voltage. The CAT3200-5 gives a fixed regulated
5V output. The CAT3200 has an adjustable output
using external resistors. The constant frequency 2MHz
charge pump allows small 1 F ceramic capacitors to
be used.
Maximum output loads of up to 100mA can be
supported over a wide range of input supply voltages
(2.7V to 4.5V) 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 A.
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 CAT3200-5 is available in a 6-lead, 1mm max
thin SOT23 package. The CAT3200 is available in an
8-lead MSOP package.
