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)
• 3.3V @ 50mA Always On (Linear)
• 12V/Adjustable @ 120mA Boost (PWM)
• >96% efficiency
• Hysteretic mode for light loads
• PWM mode for normal loads
• Main regulators switch out of phase
• 300kHz fixed frequency switching
• RDS(ON) current sense over-current
• Reduced BOM; Max. efficiency
• Optional current sense resistor for precision over-current
