Hello, I'm trying to implement a DC DC boost circuit using the FAN5331 (See: http://www.fairchildsemi.com/ds/FA/FAN5331.pdf and test circuit on Pg 3.)
See attachment for what I set up on the breadboard for the test circuit. Note that I had to use BAT46 instead of BAT54 as there is no through hole version of BAT54.
WHen I tested this circuit, I was getting an incorrect output (0.3 V instead of 15+ V). So to test, I put my multimeter nodes across the wires of the 10mH inductor. As soon as I did that, the IC blew up and started smoking. Any idea why this happened?
The input is 5V DC
