Preset/Adjustable Output CMOS Inverting Switching Regulators

Description

The MAX635/MAX636/MAX637 inverting switching regulators are designed for minimum component DC-DC conversion in the 5mW to 500mW range.Low power applications require only a diode, output filter capacitor, and a low-cost inductor. An additional MOSFET and driver are needed for higher power applications. Low battery detection circuitry is included on chip.The MAX635/MAX636/MAX637 are preset for -5V, -12V, -15V outputs, respectively. However, the regulators can be set to other levels by adding 2 resistors.Maxim manufactures a broad line of step-up, step-down, and inverting DC-DC converters, with features such as logic-level shutdown, adjustable oscillator freuqency, and external MOSFET drive.ApplicationsBattery Power ConversionBoard Level DC-DC ConversionMinimum Component, High -Efficiency DC-DC ConvertersPortable Instruments
