MAX887, 100% Duty Cycle / Low-Noise / Step-Down / PWM DC-DC Converter
The MAX887 high-efficiency, step-down DC-DC converter provides an adjustable output from 1.25V to 10.5V.
It accepts inputs from 3.5V to 11V and delivers 600mA.
Operation to 100% duty cycle minimizes dropout voltage (300mV typ at 500mA).
Synchronous rectification reduces output rectifier losses, resu
