DC DC Buck convertor design using L6986F not working on PCB Board.

hi all,i have designed DC DC Buck convertor using L6986F convertor for 3.3V, 5V and 12V output respectively with input voltage of 24V DC. we tested the circuit and observed that at 3.5V input we are getting same 3.5V at the output port of 3.3V,5V and...

LNBH26S Thermal Performance

I am testing the LNBH26S with 430mA load at 18V on both channels of the chip, and on the bench the LNB chip reaches up to 100degC according to a thermal camera. Is this temperature at this load normal for the LNBH26S? My device needs to be weather pr...
