General Description
The MAX639/MAX640/MAX653 step-down switching regulators provide high efficiency over a wide range of load currents, delivering up to 225mA. A current-limiting pulse-frequency-modulated (PFM) control scheme gives the devices the benefits of pulse-width-modulated (PWM) converters (high efficiency at heavy loads), while using only 10μA of supply current (vs. 2mA to 10mA for PWM converters). The result is high efficiency over a wide range of loads.
Features
? High Efficiency for a Wide Range of Load Currents
? 10μA Quiescent Current
? Output Currents Up to 225mA
? Preset or Adjustable Output Voltage:
??? 5.0V (MAX639)
??? 3.3V (MAX640)
??? 3.0V (MAX653)
? Low-Battery Detection Comparator
? Current-Limiting PFM Control Scheme
Applications
??? 9V Battery to 5V, 3.3V, or 3V Conversion
??? High-Efficiency Linear Regulator Replacement
??? Portable Instruments and Handy-Terminals
??? 5V-to-3.3V Converters
