UCC28630, UCC28631, UCC28632 and UCC28633, High-Power Flyback Controller  
with Primary-Side Regulation and Peak-Power Mode  
1 Features  
3 Description  
The UCC2863x targets high-power, primary-side  
regulated flyback converters. The powerful gate driver  
and ability to operate in both CCM and DCM make  
the device suitable for applications with a wide power  
range. The peak power mode allows transient peak  
power delivery up to 200% of nominal rating, with  
only a 25% peak current increase, maximizing  
transformer utilization.

High-Power, Primary-Side Regulation for Output  
Voltage and Current, No Opto-Coupler Required  
•
Continuous Conduction Mode (CCM) and  
Discontinuous Conduction Mode (DCM) Operation  
•
•
Built-In 700-V Start-Up Current Source  
Active X-Capacitor Discharge Function  
(UCC28630 and UCC28633)  
The transformer bias winding is used to sense output  
voltage for regulation, and for low-loss input voltage  
sensing. Advanced sampling and processing  
techniques allow CCM operation, and deliver  
excellent output voltage regulation performance for  
opto-coupler-less designs at power levels of 100 W  
and above.  
•
Adjustable Constant-Current (CC) Mode Limiting  
(except for UCC28630)  
•
•
•
High Gate Drive Current 1-A Source and 2-A Sink  
Low Power Modes for <30-mW System Standby  
Best-In-Class Light Load (10%) Efficiency >85%  
for 65-W Nominal Power Design  
•
•
•
Peak-Power Mode for Transient Overload  
Shutdown Pin Interface for External NTC  
A high-voltage current source enables fast and  
efficient start-up. Advanced light-load modes are  
deployed (including switching frequency modulation  
and device sleep modes) to reduce both controller  
and system power consumption at no load and light  
load. These modes enable potential system designs  
to meet 30-mW no-load power for power designs up  
to 30 W nominal, 60 W peak.  
Protections: Overvoltage, Overcurrent, Over-  
Temperature, Overload Timer (UCC28630), AC  
Line UV, Brownout and Pin Protections  
•
Frequency Dither to Ease EMI Compliance  
(except the UCC28632)  
The device has been designed for ease-of-use and  
incorporates many features to enable a wide range of  
designs. Extensive protection features are included to  
simplify system design.
