GENERAL DESCRIPTION
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. It also provides the protections with latched shut down including over temperature protection (OTP), and
