MAX747MJD规格书详情
General Description
The MAX747 high-efficiency, high-current, step-down controller drives external P-channel FETs. It provides 90 to 95 efficiency from a 6V supply with load currents ranging from 50mA up to 2.5A. It uses a pulse-width-modulating (PWM) current-mode control scheme to provide precise output regulation and low output noise. The MAX747’s 4V to 15V input voltage range, a fixed 5V/adjustable (Dual-Mode™) output, and a current limit set with an external resistor make this device ideal for a wide range of applications.
