FAN5230  
System Electronics Regulator for Mobile PCs  
Features  
Description  
• 5.4V to 24V input voltage range  
• Five regulated outputs:  
• 5V @ 5A (PWM)  
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.  
• 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  
detect  
• Power Good signal for all voltages  
• Input under-voltage lock-out (UVLO)  
• Thermal shutdown  
• ACPI compliant  
• 24-pin QSOP  
The two primary PWM controllers in the FAN5230 use  
synchronous-mode rectification to provide 3.3V and 5V at  
over 5A each. They switch out-of-phase to minimize input  
ripple-current. Utilization of both input and output voltage  
feedback in a current-mode control allows for fast and stable  
loop response over a wide range of input and output  
variations. PWM control in normal operation and hysteretic  
control under light load provides efficiency of greater than  
95% over a wide range of input and output variations. The  
third PWM controller generates 12V at 120mA. A propri-  
etary technology is used for accurate [± 1%] sensing of out-  
put current using the RDS(ON) of the external MOSFETs,  
eliminating external current sense resistors which saves  
board space and reduces BOM cost.  
• 2nd source by Intersil (IPM6220)  
Two integrated linear regulators provide stand-by ALWAYS-  
ON power at 3.3V and 5V for light (50mA) loads. Additional  
FAN5230 features include over-voltage, under-voltage, and  
over-current monitors and thermal shutdow protection.  
A single Power-Good signal is issued when soft start is  
completed and all outputs are within ± 10% of their settings.  
Applications  
• Notebook PCs  
• Web tablets  
• Battery-powered instruments
