Function : High Performance Current Mode PWM Controller
Package : DIP 8, SOT-23-6 Type
Maker : On-Bright
Pinouts : 
Description :
OB2273AP, OB2273 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications.
PWM switching frequency at normal operation is internally fixed and is 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. Power on Soft Start Reducing MOSFET Vds Stress
2. Frequency shuffling for EMI
3. Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power
Design
4. Audio Noise Free Operation
5. Fixed 65KHZ Switching Frequency
6. Comprehensive Protection Coverage
