The MAX631, MAX632, and MAX633 are +5V, + 12V, and +15V fixed output, step-up DC-DC converters for use in low-power, high-efficiency switching regulator applica tions. 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 Ordering Information MAX631/632/633 can also be set for other output volt ages by adding an external voltage divider.
Maxim manufactures a broad line of step-up, step-down, and inverting DC-DC converters, with features such as logic-level shutdown, adjustable oscillator frequency, and external MOSFET drive.
