General Description
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
provide precise output regulation and low output noise. The MAX746s 4V to 15V
input voltage range, fixed 5V/adjustable (Dual-ModeTM) output, and adjustable
current limit make this device ideal for a wide range of applications.
High efficiency is maintained with light loads due to a proprietary automatic
pulse-skipping control (Idle-ModeTM) scheme that minimizes switching losses by
reducing the switching frequency at light loads. The low 950µA quiescent
current and ultra-low 1.4µA shutdown current further extend battery life.
