How to choose an analogue of a PWM controller?

Question

Iron

I ask for help in identifying and selecting an analog for a PWM controller. It seems to be similar to the LM5119, but you can’t find it on sale. In this connection, I would like to pick up an analogue. Thanks

Answer 1

buy on Digikey or Mouser, both have this chip, i.e. It's just a matter of price + shipping.
to select an analogue in the same place, in the same sections in which this microcircuit is located, setting the case, type, voltage, etc. ... there are no analogues compatible in legs offhand and it is extremely doubtful that they will be - the controller is clearly not Shirpotrebovsky. analogues of functional - quite a lot.
