OB2298 PWM Controller with PFC Standby Control GENERAL DESCRIPTION OB2298 is a highly integrated current mode PWM controller for medium to high power offline flyback converter applications. OB2298 integrates PFC IC power supply control function and shuts down PFC stage at no load or light load conditions. To meet the increasing stringent standby power requirements in light or zero load, OB2298 operates in On-Bright’s proprietary “extended burst mode” without audio noise. Constant power limit is achieved by On-Bright’s proprietary OCP compensation technique where OCP due to CCM and DCM mode difference is compensated in universal AC input applications.
