1 / 12 page © Semiconductor Components Industries, LLC, 2010 May, 2010 − Rev. 13 1 Publication Order Number: CAT3200/D 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 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.
