    Start-up and steady-state models of microcontroller

    I've been looking at UCC28C43 models provided by TI. Why do we need two different Spice models such as "Transient steady-state" & "transient start-up" for MOSFET driver IC? How do we use them? When do we need these analyses? Do all microcontrollers in power electronics have such separate models...

    AC/DC converter (110VAC to 12VDC, 120W)

    I'm looking to design a PCB that will have a 110VAC input and convert it to 24VDC output with a maximum load current of 5A. Is mounting the step down transformer on the PCB a good idea? What better ways are there to do it?

    DC/DC Converter VS AC/DC Converter

    If you are using several different DC voltages inside a unit, (say 5v, 12v, 48v) ignoring efficiency, would it be better to use separate AC/DC power supplies for each voltage or use 1 AC/DC power supply for the highest DC voltage and step down the voltage with DC/DC converters from there?

    Power Supply and Reference Points

    Hey folks. I’ve been working on a home project involving a low power AC/DC converter based on the power integrations ref (https://www.mouser.com/datasheet/2/328/rdr623-1487555.pdf). There were some minor changes, I added a current limiter to keep to spec, and in addition the circuitry has a...

    TOP209P power integration IC

    Hello everyone Please can someone tell me if this IC ( TOP209P ) is the same AS this one ( TYNY275PN) Is it doing the same functions? Can I replace the TOP209P with TYNY275PN ? THANK YOU SO MUCH
