GENERAL DESCRIPTION
FEATURES
PT2602C is a high performance secondary
side switch for synchronous rectification (SR) in
DCM operation flyback.
Match DCM and Quasi-Resonant flyback
converter
Supports
High-side
and
Low-side
rectification
Using SR to replace diode can effectively
reduce the secondary side rectifier power
dissipation and increase efficiency for system.
PT2602C is offered in SOP-8 package.
