OB5269B High Voltage Green Mode PWM Controller with Brownout GENERAL DESCRIPTION OB5269B is a highly integrated current mode PWM control IC with high voltage start up, optimized for high performance, low standby power consumption and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to a tight range. At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss. Very low standby power consumption and very high conversion efficiency is thus achieved. High voltage startup is implemented in OB5269B, which features with short startup time and low standby current.
