General Description

The MAX1966/MAX1967 are voltage-mode pulse-widthmodulated (PWM), step-down DC-DC controllers that are ideal for a variety of cost-sensitive applications.

They drive low-cost N-MOSFETs for both the high-side switch and synchronous rectifier and require no external Schottky power diode or current-sense resistor.

Shortcircuit and current-limit protection is provided by sensing the drain-to-source voltage on the low-side FET.
