    MAX1649
    5V/3.3V or Adjustable, High-Efficiency, Low-Dropout, Step-Down DC-DC Controllers
    
General Description
The MAX1649/MAX1651 BiCMOS, step-down, DC-DC switching controllers provide high efficiency over loads ranging from 1mA to more than 2.5A. A unique, current limited pulse-frequency-modulated (PFM) control scheme gives these devices the benefits of pulse-width-modulation (PWM) c
