LNK6764K

Posted by: Josef on

In a current design of a power supply 12V/15W we are using LNK6764K.

We have problems in sourcing the diode on the secondary side.

What are the requirements for the diode?

What influence does the forward voltage of the diode have on the output voltage?

A schematic of the power supply is attached

Hi,

You can replace with another schottky diode, however try to use the similar package.

If the forward voltage drop is higher then the diode loss is going to be different. Apart from that the regulation may get affected slightly.
