Description
OB2362I Adaptive Multi-Mode PWM Controller GENERAL .
OB2362I is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback conver.
Features
* Power on soft start reducing MOSFET Vds stress
* Multi-Mode Operation 100KHz fix frequency mode @ Full Load Valley switching operation @ Green mode Burst Mode @ Light Load & No Load
* Frequency shuffling for EMI
* Extended burst mode control for improved
efficiency and low standby
Applications
* At full loading, the IC operates in fixed frequency (100KHz) mode. When the loading goes low, it operates in Green mode with valley switching for high power conversion efficiency. When the load is very small, the IC operates in ‘Extended Burst Mode’ to minimize the standby power loss. As a result,
