CAT3200HU2数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The CAT3200HU2 is a switched capacitor boost converter that delivers a low noise, regulated output voltage. The CAT3200HU2 gives a fixed regulated 5 V output when the FB pin is tied to ground, otherwise it provides an adjustable output using external resistors. The constant frequency 2 MHz charge pump allows small 1 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 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 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.
