CAT3200
CAT3200 is Low Noise Regulated Charge Pump DC-DC Converter manufactured by onsemi.
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 m F ceramic capacitors to be used.
Maximum output loads of up to 100 m A 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 m 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, 1 mm...
