General Description

OBGZ11 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications.

PWM switching frequency at normal operation is internally fixed and is trimmed to tight range.

At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss.
