UC3846: Transformer driver

Ilya Mazurenko

Part Number: UC3846

Hello Team,

Is it possible to use UC3846 as a transformer driver without foreign switches?
As i see, it has internal bridge circuit and if we need not large current on the output of transformer it should work. Is't it?

Hi Ilya,

Thanks for your interest in UC3846. How much current do you need to drive your transformer?

Hi Ilya,

This should be ok. The internal totem pole drivers are capable of 500mA peak.
