MAX17024 Datasheet Single Quick-pwm Step-down Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1040; Rev 0; 10/07 EVAALVUAAILTAIOBNLEKIT Single Quick-PWM Step-Down Controller with Dynamic REFIN MAX17024.

General Description

The MAX17024 pulse-width modulation (PWM) controller provides high efficiency, excellent transient response, and high DC-output accuracy needed for stepping down high-voltage batteries to generate lowvoltage 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.

The REFIN adjustability combined with a resistive voltage-divider on the feedback input allows the MAX17024 to be configured for any output voltage between 0 to 0.9 x VIN.
