    DC-DC step down converter in Orcad

    I want to use a DC-DC buck converter MP1492DS in Orcad 9.2. Could someone please tell me in which library could i find it?

    a question for Cadence OrCAD

    I guess the USA OrCAD distributor is here: https://www.ema-eda.com Orcad is a really expensive software so if you are using it in your home then there is no need to buy it. you can use orcad 9.1 instead.

    electronic switch design

    when i increased the time step to 100uS then it showed error after 10% that the voltages and current failed to converge. ---------- Post added at 10:35 ---------- Previous post was at 09:24 ---------- tried by keeping the on off time to 1 s but still getting the same results

    electronic switch design

    the transistor is showing the clock pulse as it is. the output voltage across the load is now rising linearly

    electronic switch design

    i want that my uC should give the on pulse for 5 min and off pulse for 5 min. but as orcad is taking ages to simulate those values so i have reduced the time for simulation ---------- Post added at 16:09 ---------- Previous post was at 16:07 ---------- i changed the circuit and had placed...

    electronic switch design

    i tried to change the position of the ac source but the circuit is not switching the output. i am still getting perfect ac voltage at the output. what could be the cause of this?

    electronic switch design

    but if i do not connect the ground with the ac supply the program shows errors for floating nodes[COLOR="Silver"] could you tell me if there is anything wrong with the circuit

    electronic switch design

    i am using 8085 microcontroller. i want to switch my circuit for ac voltage so why should i supply dc voltage in my schematic. plz explain

    electronic switch design

    i am trying to build a simple electronic switch with a transistor, relay and a microcontroller. i want to turn on the relay only when ethe microcontroller gives a high output. i am trying to simulate this circuit but cannot get the desired ac output. please help me on this.
