FEATURES  
DESCRIPTION  
•
Frequency Foldback Reduces Operating  
Frequency Under Fault Conditions  
The UCC3884 is a high performance current mode  
PWM controller intended for single ended switch  
mode power supplies. The chip implements  
•
•
•
•
•
•
Accurate Programmable Volt-Second Clamp  
Programmable Maximum Duty Cycle Clamp  
Oscillator Synchronization  
a
frequency foldback scheme that decreases the  
oscillator frequency as the output voltage falls below  
a programmed value. This technique decreases the  
average output current sourced into a low impedance  
load which can occur during an output short circuit or  
overload condition. Excessive short circuit current is  
more prevalent in high frequency converters where  
the propagation delay and switch turn-off time forces  
Overcurrent Protection  
Shutdown With Full Soft Start  
Wide Gain Bandwidth Amplifier (GBW > 2.5  
MHz)

Current Mode Operation  
Precision 5-V Reference  
a
minimum attainable duty cycle. An accurate  
volt-second clamp limits the duty cycle during line or  
load transient conditions which could otherwise  
saturate the transformer. The volt-second clamp may  
also be used with an external overvoltage protection  
circuit to handle fault conditions such as current  
sense disconnect or current transformer saturation.  
The frequency foldback, volt-second clamp,  
cycle-by-cycle current limit, and overcurrent shutdown  
provide a rich set of protection features for use in  
peak current-mode pulse width modulators.
