Datasheet Summary
High Performance Current Mode PWM Controller
GENERAL DESCRIPTION
Features
OB2276A is a highly integrated current mode
- Power on Soft Start Reducing MOSFET Vds
PWM control IC optimized for high performance,
Stress low standby power and cost effective offline
- Frequency shuffling for EMI flyback converter applications.
- Extended Burst Mode Control For Improved
PWM switching frequency at normal operation is
Efficiency and Minimum Standby Power internally fixed and is trimmed to tight range. At no
Design load or light load condition, the IC operates in
- Audio Noise Free Operation extended ‘burst mode’ to minimize switching loss.
- Fixed 65KHZ Switching Frequency
