UCC28063EVM-723 Datasheet PDF - TI

The UCC28063EVM-723 is a fully assembled and tested circuit for evaluating the UCC28063 natural interleaving transition mode PFC controller. The evaluation module is an off line 300W PFC pre regulator that runs of a universal line input of 85V to 265V RMS and provides a regulated 390V output. The evaluation module demonstrates how the UCC28063 IC can be used in an interleaved transition mode PFC pre regulator.

● Phase management capability

● FailSafe OVP with dual paths prevents output over voltage conditions by voltage sensing failures

● Soft start on overvoltage

● Integrated brownout

● Input filter and output capacitor current cancellation

● Enables use of low cost diodes without extensive snubber circuitry

● Improved light load efficiency

● Improved transient response

● Complete system level protection

● 1A Source/1.8A sink gate drivers

●There are high voltages present on the pre-regulator. It should only be handled by experienced power supply professionals.
