Current Mode PWM ControllerFrequency Shuffling
Tone energy at below 20KHZ is minimized in the design and audio noise is eliminated during operation.
OB2263 is offered in SOT23-6, SOP-8 and DIP-8 packages.
GENERAL 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 th...
