CAT3200HU2:DC-DC, 2x Charge Pump, 5.0 V & Adjustable, 100 mA
The CAT3200HU2 and CAT3200HU2-5 are switched capacitor boost converters that deliver a low noise, regulated output voltage. The CAT3200HU2-5 gives a fixed regulated 5.0 V output. The CAT3200HU2 has an adjustable output using external resistors. The constant frequency 2.0 MHz charge pump allows small 1.0 µF 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 1.0 µA. 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 CAT3200HU2-5 is available in a 6-lead, 1 mm max, thin SOT23 package. The CAT3200HU2 is available in an 8-lead MSOP package.
