Part Number OB5269B
Description High Voltage Green Mode PWM Controller
Feature OB5269B High Voltage Green Mode PWM Cont roller with Brownout GENERAL DESCRIPTI ON OB5269B is a highly integrated curre nt mode PWM control IC with high voltag e start up, optimized for high performa nce, low standby power consumption and cost effective offline flyback converte r applications.
PWM switching frequency at normal operation is internally fixe d and is trimmed to a tight range.
At n o load or light load condition, the IC operates in extended ‘burst mode’ t o minimize switching loss.
Very low sta ndby power consumption and very high co nversion efficiency is thus achieved.
