BD5650AFVM
No.10032EBT02
●Description
BD5650AFVM is small controller built in high accuracy reference voltage, constant voltage controlled amplifier and over
current detection. BD5650AFVM functions as constant voltage control to realize stable power supply and abnormal
(open-collector ON) output in case a controller continues to detect over current overtime. A time until driving is flexible
depend on external capacitance.
●Features
1) Constant voltage control
2) Supply voltage range: 2.5V～18V
3) High accuracy reference voltage: 1.21V±1%
4) Current detected voltage: 73mV±5%(0～85℃)
5) Built-in over current detection with delay time
6) Small package: MSOP8
●Applications
It is suitable for secondary side controller in AC/DC adaptor to protect from over current.
●Absolute Maximum Ratings (Ta=25℃)
