Description: High Performance Current Mode PWM Contro ller OB2273 GENERAL DESCRIPTION OB227 3 is a highly integrated current mode P WM control IC optimized for high perfor mance, low standby power and cost effec tive offline flyback converter applicat ions. PWM switching frequency at normal operation is internally fixed and is t rimmed to tight range. At no load or li ght load condition, the IC operates in extended ‘burst mode’ to minimize s witching loss. Lower standby power and higher conversion efficiency is thus ac hieved. VDD low startup current and low operating current contribute to a reli able power on startup and low standby d esign with OB2273. OB2273 offers comple te protection coverage with auto-recover
