The CAT3200HU2 is a switched capacitor boost converter that provides a low noise, regulated output voltage. The CAT3200HU2 provides a fixed regulated 5 V output when the FB pin is grounded, otherwise an adjustable output using an external resistor. A 2 MHz constant frequency charge pump allows the use of small 1 µF ceramic capacitors. The device can support up to 100 mA maximum output load over a wide input supply voltage range for battery powered applications. A shutdown control input allows the device to be placed in power-down mode, reducing supply current to less than 1 µA. In the event of a short circuit or overload condition, the device is fully protected by current limiting and thermal overload detection. Additionally, soft-start, slew-rate control circuitry limits inrush current during power-up.
