5V/3.3V/3V/Adjustable, High-Efficiency, Low IQ, Step-Down DC-DC Converters

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) converter
