Adapters

•

Sensorless Current-Shaping Simplifies Board

Layout and Improves Efficiency

LCD, Plasma and DLP™ TVs

Home Audio Systems

•

Advanced Audible Noise Performance

Non-linear Error-Amplifier Gain

3 Description

This part is identical to UCC28063 with the exception

that the TSET pin Open/ Short Fault Detect and the

CS pin Open Fault Detect features are removed.

Removal of these Fault Detect features provides a

higher degree of noise immunity to provide increased

"ride-through" for applications where significant

voltage noise could be coupled onto the TSET or CS

pins during conditions of fast transient, surge or

impulse noise on the AC Supply.

Improved Efficiency and Design Flexibility Over

Traditional Single-Phase Continuous Conduction

Mode (CCM)

•

Inrush-Safe Current Limiting:

–

Prevents MOSFET Conduction During Inrush

Eliminates reverse Recovery Events in Output

rectifiers

Device Information⁽¹⁾

•

Enables Use of Low-Cost Diodes Without

Extensive Snubber Circuitry
