CAT3200TDI-GT3

The CAT3200TDI-GT3 is a switched capacitor Boost Converter delivers a low noise ad regulated output voltage. The CAT3200 has an adjustable output using external resistors. The constant frequency 2MHz charge pump allows small 1μF ceramic capacitors to be used. Maximum output loads of up to 100mA can be supported over a wide range of input supply voltage (2.7 to 4.5V) 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 1A. 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.

• Soft-start and slew rate control
