UC3842A: Control Method

Part Number: UC3842A
Other Parts Discussed in Thread: TPS40053,

Dear Team,

Here is Kevin from Delta Taiwan.

The customer is looking for material that discusses buck control method with synchronous.

Do we have suitable training material can share with customer?

Or we have a comparison between different control scheme with synchronous FET?



  • Hi,

    I think the synchronous rectifier buck can be found by searching google. If you want to use a particular device for sync buck, it seems UC3842A is old. Can you look at TPS40053 which is dedicated for sync buck. Then you can ask support for that device.
