OB2269 Current Mode PWM Controller

OB2269 Description

GENERAL .
OB2268/9 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback conve.

OB2269 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)

OB2269 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.
