FAN5233  
System Electronics Regulator for Mobile PCs  
Features  
Description  
• 5.4V to 24V input voltage range  
• Five regulated outputs:  
• 5V @ 5A (PWM)  
The FAN5233 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 one linear regulator 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)  
• 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 TSSOP  
The two primary PWM controllers in the FAN5233 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 sensing of output current using  
the RDS(ON) of the external MOSFETs, eliminating exter-  
nal current sense resistors which saves board space and  
reduces BOM cost.  
Applications  
• Notebook PCs  
• Web tablets  
• Battery-powered instruments  
One integrated linear regulator provides stand-by  
ALWAYS-ON power at 5V for light (50mA) loads.  
Additional FAN5233 features include over-voltage, under-  
voltage, and over-current monitors and thermal shutdown  
protection. A single Power-Good signal is issued when soft  
start is completed and all outputs are within 10% of their  
settings.
