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
5V output. The CAT3200 has an adjustable output
using external resistors. The constant frequency 2MHz
charge pump allows small 1µF 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.
s Local 5V supply from lower rail
s Battery backup systems
s Handheld portable devices
A shutdown control input allows the device to be
placed in power-down mode, reducing the supply
current to less than 1µA.
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.
