CAT3200 and CAT3200-5 are the switched-capacitor boost converter, which can output low-noise adjustable voltage. CAT3200-5's fixed output voltage is 5V. CAT3200 can use an external resistor to make the output voltage be adjustable. Their frequency is fixed at 2MHz 1μF, and the charge pump allows to use small ceramic capacitors, and wide input supply voltage range (2.7 ~ 4.5V) supports the maximum 100mA output load that allows the device ideal for battery-powered electronic device. Their shutdown control input allows the device to enter power-down mode, which allows the supply current to be less than 1μA.
