FAN5230QSC Description

For laptop computers and other battery-powered devices, the FAN5230QSC is a multiple-output voltage regulator with great efficiency and precision. To transform 5.4V to 24V notebook battery power into the voltage required by the circuitry that surrounds the microprocessor in these systems, it includes three pulse-width modulated (PWM) switching regulator controllers and two linear regulators.
