    Hi All need help again, does anyone know of a MCP1416 equivalent, as you all know the MCP1416 is a very tiny SMD and I am having trouble attaching it to my strip board, so looking for non-inverting DIP if that make any sense

    Thanks

    Have a look at the datasheet and compare it to others.

    What about a Maxim5048A, lower supply but higher current output, different pinout.

    Is this the same project that you asked about in March? And if so, have you tried it without the MCP1416 as I suggested back then?

    Yes it is the same project, a very slow one, no I have not tried without, would I connect pin 3 of 555 direct to gate on mosfet ?

    Usually, there is a small resistance (10 to 100 Ω) used to connect pin 3 to the gate. In addition, the gate should be tied to ground with a 10k resistor. Both resistors can be 1/4 watt.

    The problem I had was the 15 ohm resistor that when from pin 3 of the 555's to pin 3 of the MCP1416 got super hot and burnt out, this happened because me being the Div that I am, I thought pin 2 of the mosfet was the gate, dont ask me why I thought that.
    I checked the output from pin 3 of the 555 and was getting a good 90% duty cycle, then I checked the output of pin 5 of the MCP1416, and was not getting the same so I assumed the MCP1416 was damaged as well, I do have 1 more left so I try and solder that to me strip board again and see what happens

    Thanks

    Pin 1 of the PSMN017-30PL is the gate.

    Put that MCP1416 in if you want it, but it isn't needed.
