The MAX631, MAX632 and MAX633 are 5 ,12 and 15 volts fixed output, step-up DC-DC converters for use in low-power, high-efficiency switching regulator applications. The only external components required are an output filter capacitor and a low-cost inductor. Included on-chip are low battery detection circuitry and a charge pump output for generating a negative voltage in dual supply applications.
Though most simply used as fixed output regulators, the MAX631/632/633 can be set for other output voltages by adding an external voltage divider.
