Part Number : AP8263
Function : PWM CONTROLLER GREEN MODE
Package : SOT-26 Type
Manufactures : AiT Semiconductor
AP8263 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.
The internal slope compensation improves system large signal stability and reduces the possible
subharmonic oscillation at high PWM duty cycle output. Leading-edge blanking on current sense(CS)
input removes the signal glitch due to snubber circuit diode reverse recovery andthus greatly reduces the
external component count and system cost in the design.
Excellent EMI performance is achieved with proprietary frequency shuffling technique together
with soft switching control at the totem pole gate drive output.
