OB2362C
Adaptive Multi-Mode PWM Controller
GENERAL DESCRIPTION
FEATURES
OB2362C is a highly integrated current mode ■ Power on soft start reducing MOSFET Vds
PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. At full loading, the IC operates in fixed frequency (65KHz) mode. When the loading goes low, it operates in Green mode with valley switching for
stress ■ Multi-Mode Operation
65KHz fixed frequency mode @ Full Load Valley switching operation @ Green mode Burst Mode @ Light Load & No Load
high power conversion efficiency. When the load is ■ Frequency shuffling for EMI
very small, the IC operates in ‘Extended Burst ■ Extended burst mode control for improved
Mode’ to minimize the standby power loss.
