MAX746 High-Efficiency / PWM / Step-Down / N-Channel DC-DC Controller

The MAX746 is a high-efficiency, high-current, step-down DC-DC power-supply controller that drives external N-channel FETs. It provides 93% to 96% efficiency from a 6V supply voltage with load currents ranging from 50mA up to 3A. It uses a pulse-width-modulating (PWM) current-mode control scheme to .

MAX746 Features

* a 2V ±1.5% reference, a comparator for low-battery detection or level translating, and soft-start and shutdown capability. The MAX747

* discussed in a separate data sheet

* functions similarly to the MAX746, but drives P-channel logic level FETs. ____________________________Features o
