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 1F 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 1A.

In the event of short circuit or overload conditions, CAT3200 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.
