OB2268CP datasheet

 

Description

The OB2268, OB2268CP, OB2269 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.

OB2263 datasheet

Description

OB2263 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter 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.

Features

1. On-Bright Proprietary Frequency Shuffling Technology for Improved EMI Performance.

2. Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design

3. Audio Noise Free Operation

4. External Programmable PWM Switching Frequency

5. Internal Synchronized Slope Compensation

6. Low VDD Startup Current and Low Operating Current (1.4mA)

7. Leading Edge Blanking on Current Sense Input
