OB5269B Datasheet

OB5269B High Voltage Green Mode PWM Controller

OB5269B is a highly integrated current mode PWM control IC with high voltage start up, optimized for high performance, low standby power consumption and cost effective offline flyback converter applications. PWM switching frequency at normal operation is internally fixed and is trimmed to a tight ra.

Features

with short startup time and low standby current. OB5269B offers complete protection coverage with auto-recovery including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), brownout protection and VDD under voltage lockout (UVLO). It also provides the protections with latched shut down including over temperature protection (OTP), and .
