Infineon, Resonant Controller 8-Pin, PG-DSO-8 ICE5QSBGXUMA1

The Infineon Quasi-resonant, is the 5th generation of quasiresonant controller optimized for off-line switch power supply in cascode configuration. The improved digital frequency reduction with proprietary novel Quasi-Resonant operation offers lower EMI and higher efficiency for wide AC range by reducing the switching frequency difference between low and high line. The enhanced active burst mode enables flexibility in standby power range selection. The product has a wide operating range of IC power supply and lower power consumption. The numerous protection functions including the robust line protection to support the protections of the power supply system in failure situations.

Enhanced Active Burst Mode with selectable entry and exit standby power
Active Burst Mode to reach the lowest standby power <100 mW
Fast start-up achieved with cascode configuration
Digital frequency reduction up to 10 zero crossings
Built-in digital soft start
Cycle-by-cycle peak current limitation
Maximum on/off time limitation to avoid audible noise during start up and power down
Robust line protection with input OVP and brownout
