Hi

 

Here’s a guy with a schematic of the same thing running a 2153. I’d bet what is on

the board is pretty close to what he shows.

By the spec sheet for the IR2153D, you absolutely can run it at 800 Hz.

Just change the R-C values accordingly.

Not sure what chip they use on the thing and how freq is set. Anyone have one 
and can let us know what the 8 pin DIP is?
