Description
OB2262 Current Mode PWM Controller GENERAL .
OB2262 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback convert.
Features
* Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design
* Audio Noise Free Operation Programmable PWM Switching
* External Frequency
* Internal Synchronized Slope Compensation
* Low VDD Startup Current and Low Operating Current (1.4mA)
* Leading Edge
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. www. Dat
