توضیحات
OB2263MP CODE 63G4 SOT23-6 ORIGINAL
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 thus achieved.
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.
