The MAX747 high-efficiency, high-current, step-down controller drives external P-channel FETs.

a 2V ±1.5% reference, a comparator for low-battery detection or level translating, as well as soft-start and shutdown capability. The MAX746, discussed in a separate data sheet, functions similarly to the MAX747, but it drives N-channel logic level FETs on the high side. ____________________________Features o 90% to 95% Efficiency for 50mA to 2.5A Output Currents o 4V to 15V Input Voltage Range o Low 800µA Supply Current o 0.6µA Shutdown Current o Drives External P-Channel FETs o Cycle-by-Cycle.
