UC3584  
Secondary Side Synchronous Post Regulator  
FEATURES  
DESCRIPTION  
Practical Operation at Switching  
Frequencies up to 1MHz  
The UC3584 is a low voltage, Secondary Side Synchronous Post Regula-  
tor. It is intended to be used for auxiliary output voltage regulation in single  
secondary winding, multiple output power supplies (for more details refer  
to the Application Section of this Data sheet). The UC3584 is most suited  
for systems where the main output is regulated between 5V and 14V. Out-  
put voltages regulated by the UC3584 can range from virtually 0V up to  
the output voltage of the main output.  
Wide Band Error Amplifier  
Undervoltage Lockout with Hysteresis  
Output Active Low During UVLO  
Soft Start/Maximum Duty Cycle  
Control  
Auxiliary output voltage regulation with the UC3584 uses leading edge  
modulation making it compatible to primary side peak current or voltage  
mode control. The UC3584 clock circuit is synchronized to the switching  
frequency utilizing the falling edge of the transformer’s secondary winding  
waveform.
