Descripiton :
OB2268/9 is a highly integrated current mode PWM control IC optimized for high performance, low
standby power and cost effective offline flyback converter applications in above 20W power level.
PWM switching frequency at normal operation is externally programmable and trimmed to tight range. At no load or light load condition, the IC operates in extended burst mode to minimize switching loss. Lower standby power and higher conversion efficiency is thus achieved.

Features :
* Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design
* Audio Noise Free Operation
* External Programmable PWM Switching Frequency
* Internal Synchronized Slope Compensation
* Low VIN/VDD Startup Current(4uA) and Low Operating Current (2.3mA)
* Leading Edge Blanking on Current Sense Input
* Complete Protection Coverage With Auto SelfRecovery
* External Programmable Over Temperature Protection (OTP)
* With or Without On-chip VDD OVP for Output Over Voltage Protection.
* Under Voltage Lockout with Hysteresis (UVLO)
* Gate Output Maximum Voltage Clamp (18V)
* Line Compensated Cycle-by-Cycle Overcurrent Threshold Setting For Constant Output Current Limiting Over Universal Input Voltage Range (OCP)
* Over Load Protection. (OLP)
* On-Bright Proprietary Frequency Shuffling Technology for Improved EMI Performance (OB2269 only)
