I simulate this but don`t work |

C1 330p, not 33p. FYI, if you're looking for an out-of-the-box solution that doesn't require adjustment, this is not it. There are more reliable, discrete circuits possible, but they require more components and/or coupled inductors, and even more adjustment to create, if not necessarily to fit to a given end use. Stick with commercial boost regulators and follow the application notes. :-+ Tim |

OPS I create new but not work |

I personally use mosfets from motherboards. --- Quote from: gbg on February 25, 2019, 04:59:00 pm ---OPS I create new but not work --- End quote --- I ran the simulation myself and sure enough it doesn't work with an IRLZ44N but any other switching mosfet does work. PS: the circuit originally used a 2N3904 but i modified this one to work with a 2n2222. Also if you don't have LTspice already, please get it because it's awesome (and free). |
