Product Summary

The UCC28060 is a dual-phase transition-mode PFC controller. Optimized for high-volume consumer applications, this solution extends the advantages of transition mode—high efficiency with low-cost components—to higher power ratings than previously possible. By utilizing a Natural Interleaving technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency. The UCC28060 delivers inherently strong matching, faster responses, and ensures that each channel operates in transition mode. The applications of the UCC28060 include 100 W to 1 kW Power Supplies, LCD, Plasma, and DLP TVs, Computer Power Supplies, Entry Level Servers, Electronic Lighting Ballasts.

Parametrics

UCC28060 absolute maximum ratings: (1)Input voltage range VCC:–0.5V to +21V; (2)Input voltage range PWMCNTL: –0.5V to +20V; (3)Input voltage range COMP, CS, PHB, HVSEN, VINAC,VSENSE:–0.5V to +7V; (4)Input voltage range ZCDA, ZCDB: –0.5V to +4V; (5)Continuous input current VCC: 20mA; (6)Input current PWMCNTL: 10mA; (7)Input current range ZCDA, ZCDB, VSENSE: –5mA to +5mA; (8)Output current VREF: –10mA; (9)Continuous gate current GDA, GDB: ±25mA; (10)Operating:–40℃ to +125℃; (11)Junction temperature, TJ Storage: –65℃ to +150℃; (12)Lead temperature, TSOL Soldering, 10s: +260℃.

Features

UCC28060 features: (1)Easy Phase Management Facilitates Compliance to Light-Load Efficient Standards; (2)FailSafe OVP with Dual Paths Prevents Output Over-voltage Conditions Caused by Voltage-Sensing Failures; (3)Sensorless Current Shaping Simplifies Board Layout and Improves Efficiency; (4)Inrush Safe Current Limiting: Prevents MOSFET conduction during inrush, Eliminates reverse recovery events in output rectifiers.
