FAN5232  
Adjustable PWM Buck Controller for LCD PCs  
Features  
Description  
• Three outputs: Adjustable Buck, 3.3V-Always,  
5V-Always  
• Adjustable synchronous switcher, 5V – 80% Vin  
• 1% internal reference precision  
• Current mode with voltage feed-forward  
• Precision current limit option  
• Charge pump works at all loads  
• No shoot-through current  
• Independent shutdown pins for ACPI  
• Power Good, input UVLO, output OV  
• 5.6V to 24V input voltage range  
The FAN5232 is a high efficiency and high precision DC/DC  
controller for PCs. It has a synchronous switcher whose  
output can be adjusted from 5V up to 80% of Vin. It also has  
two linear regulators for standby, 3.3V and 5V. The PWM  
utilizes both input and output voltage feedback in a  
current-mode control, allowing for fast and stable loop  
response over a wide range of input and output variations.  
Synchronous switching provides best efficiency over a wide  
range of loads. Current sense based on MOSFET RDS,on  
gives maximum efficiency, while also permitting use of an  
optional sense resistor for high precision.  
The FAN5232 is available in a 14 pin TSSOP package.  
Applications  
• LCD PCs  
• Notebook PCs and PDAs  
• Hand-held portable instruments
