Low Noise Regulated
Charge Pump DC-DC
Converter
Description
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 5 V output. The CAT3200 has
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 (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−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 CAT3200−5 is available in a 6−lead, 1 mm max thin SOT23
package. The CAT3200 is available in an 8−lead MSOP package.
