MAX1961 - 1MHz PWM Step-Down Controllers
The MAX1960/MAX1961/MAX1962 high-current, highefficiency voltage-mode step-down DC-DC controllers operate from a 2.35V to 5.5V input and generate output voltages down to 0.8V at up to 20A.
An on-chip charge pump generates a regulated 5V for MOSFET drive.
Additionally, adaptive dead-time drivers allo
