DESCRIPTION

2000 COMPLIANT

The L6565 is a current-mode primary controller IC,

specifically designed to build offline Quasi-resonant

ZVS (Zero Voltage Switching at switch turn-on) fly-

back converters.

APPLICATIONS

■ TV/MONITOR SMPS

■ AC-DC ADAPTERS/CHARGERS

■ DIGITAL CONSUMER

Quasi-resonant operation is achieved by means of a

transformer demagnetization sensing input that trig-

gers MOSFET's turn-on.

■ PRINTERS, FAX MACHINES,

PHOTOCOPIERS AND SCANNERS
