Product Summary

The AP8263 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications in sub 30W range. PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load condition, the IC operates in extended burst mode to minimize switching loss. Its applications include Offline AC/DC flyback converter for Battery Charger, Power Adaptor, Set-Top Box Power Supplies.
