Description

The FAN5230 is a high efficiency and high precision multiple-output voltage regulator for notebook PC and other similar battery-powered applications. It integrates three pulse-width modulated (PWM) switching regulator controllers and two linear regulators to convert 5.4V-to-24V notebook battery power into the voltage used by the circuitry that surrounds the microprocessor in these systems.

Features

• 5.4V to 24V input voltage range

• Five regulated outputs:

• 5V @ 5A (PWM)

• 3.3V @ 5A (PWM)

• 5V @ 50mA Always On (Linear)
