Description
OB2263 Current Mode PWM ControllerFrequency Shuffling GENERAL .
OB2263 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback convert.
Features
* On-Bright Proprietary Frequency Shuffling Technology for Improved EMI Performance.
* Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design
* Audio Noise Free Operation
* External Programmable PWM Switching
Frequency
* Internal Synchronized Slope C
Applications
* in sub 30W range. 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
