UCC28061DR

The UCC28061DR is one member of the UCC28061 family which is designed as the Natural Interleaving transition-mode PFC controller that can be used in (1)100-W to 800-W power supplies; (2)gaming; (3)D to A set top boxes; (4)adapters; (5)LCD, Plasma and DLP TVs; (6)home audio systems applications. This device regulates the relative phasing of the channel A and channel B inductor currents to be very close to 180°, minimizing the ripple currents seen at the line source and output capacitor.

Features of the UCC28061DR are:(1)improved audible noise performance; (2)soft start on overvoltage; (3)integrated brownout; (4)enables use of low-cost diodes without extensive snubber circuitry; (5)improved light-load efficiency; (6)improved transient response; (7)complete system-level protection; (8)1-A Source/1.8-A sink gate drivers; (9)easy phase management facilitates compliance to light-load efficient standards; (10)sensorless current shaping simplifies board layout and improves efficiency.

The absolute maximum ratings of the UCC28061DR can be summarized as:(1)Lead temperature Soldering, 10s: +260 °C;(2)Junction temperature (Operating): 40 to +125 °C;(3)Junction temperature (storage): 65 to +150 °C;(4)Continuous gate current: +/-25 mA;(5)Output current: -10 mA;(6)Input current range: -5 to +5 mA;(7)Input current: 10 mA;(8)Continuous input current: 20 mA.
