Features
* OB2273 is a highly integrated current mode PWM
* Power on Soft Start Reducing MOSFET Vds
control IC optimized for high performance, low
Stress
standby power and cost effective offline flyback
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. Lower standby power and higher conversion efficiency is thus achieved. VDD low startup current and
