MAX17024ETD+T

开关控制器 Quick-PWM Step-Down w/Dynamic REFIN

Single Quick-PWM Step-Down  Controller with Dynamic REFIN

General Description

The MAX17024ETD+T MAX17024 pulse-width modulation (PWM) controller provides high efficiency, excellent transient response, and high DC-output accuracy needed for stepping down highvoltage batteries to generate low-voltage core or chipset/ RAM bias supplies in notebook computers. The output voltage can be controlled using the dynamic REFIN, which supports input voltages between 0 to 2V.
