Dual Mobile-Friendly  
PWM/PFM Controller  
FAN5234  
Description  
The FAN5234 PWM controller provides high efficiency and  
regulation with an adjustable output from 0.9 V to 5.5 V required to  
power I/O, chip−sets, memory banks, or peripherals in  
high−performance notebook computers, PDAs, and Internet  
appliances. Synchronous rectification and hysteretic operation at light  
loads contribute to a high efficiency over a wide range of loads. The  
Hysteretic Mode of operation can be disabled if PWM Mode is desired  
for all load levels. Efficiency is further enhanced by using the

TSSOP16  
CASE 948AH  
MOSFET’s R  
as a current−sense component.  
DS(ON)  
Feed−forward ramp modulation, average current mode control, and  
internal feedback compensation provide fast response to load  
transients. The FAN5234 monitors these outputs and generates  
a PGOOD (power−good) signal when the soft−start is completed and  
the output is within 10% of its set point. A built−in over−voltage  
protection prevents the output voltage from going above 120% of the  
set point. Normal operation is automatically restored when the  
over−voltage conditions cease. Under−voltage protection latches the  
chip off when the output drops below 75% of its set value after the  
soft− start sequence is completed. An adjustable over−current function  
monitors the output current by sensing the voltage drop across the  
lower MOSFET.
