OB2362
Adaptive Multi-Mode PWM Controller
GENERAL DESCRIPTION
FEATURES
OB2362 is a high performance flyback adaptive ■ Power on soft start reducing MOSFET Vds
multi-mode(CCM/QR) PWM controller, optimized
stress
to achieve high efficiency and low standby power ■ Multi-Mode Operation
with effective system cost.
CCM @ Heavy Load and Low Line
At heavy load, the IC operates in fixed frequency(65kHz) CCM mode in the low line input voltage. At medium load, it operates in QR mode ,
o at light load ,it operates in green mode with valley
skip, and at no load the IC operates in extended
a ‘burst mode’ to minimize switching loss. Lower p standby power and higher conversion efficiency is
thus achieved.
