CAT3200, CAT3200-5
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 MH- 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 (
