GENERAL DESCRIPTION
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 Self
Recovery
o External Programmable Over Temperature
Protection (OTP)
o With or Without On-chip VDD OVP for
Output Over Voltage Protection.
o Under Voltage Lockout with Hysteresis
(UVLO)
o Gate Output Maximum Voltage Clamp (18V)
o Line Compensated Cycle-by-Cycle Over
current Threshold Setting For Constant Output
Current Limiting Over Universal Input Voltage
Range (OCP)
