OB2281A 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 loss.
