OB2279 Description

RESLEEPRAILSCEAELAODSNNEFTIO:oDD2EOA7NP9NT0IDO0AT6L8COPY OB2279 Current Mode PWM ControllerFreq Shuffling with Latch Shutdown GENERAL .
OB2279 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback convert.

OB2279 Features

* On-Bright Proprietary Frequency Shuffling Technology for Improved EMI Performance
* Power On Soft Start
* Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design
* Audio Noise Free Operation
* External Programmable PWM Switching Frequency
* Inte

OB2279 Applications

* 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. VDD low startup current
