3V/3V or Adjustable, High-Efficiency, Low IQ, Step-Down DC-DC Controllers
_______________General Description
The MAX649/MAX651/MAX652 BiCMOS, step-down DCDC switching controllers provide high efficiency over three decades of load current.
A unique, current-limited pulse-frequency-modulated (PFM) control scheme gives these devices the benefits of pulse-width-modulation (PWM) converters (high efficiency at heavy loads), while using only 100µA of supply current (vs.
2mA to 10mA for PWM converters).
The result is high efficiency over loads ranging from 10mA to more than 2.
5A.
These devices use miniature external components.
Their high swit...
