Datasheet Summary
High Performance Current Mode PWM Controller
GENERAL DESCRIPTION
Features
OB2281A 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 low standby power design internally fixed and is trimmed to tight range. At no
- Audio noise free operation load or light load condition, the IC operates in
- Over Load operation with increased frequency extended ‘burst mode’ to minimize switching...
