- SMPS with UC3845 - All About Circuits
I made a simple smps with uc3845 The output of the ic is connected to IRF840 and a EE30_15_7 ferrite transformer wound by me The osc section seems to be working Vcc supplied is 16 5 v Pin 1 connected to opto coupler pin 2 to GND Pin 3 to the 0 47ohm resister connected between Mosfet

SMPs are generally programs designed for several different populations of students 1) Those who completed their science requirements in college and need to improve their academic standings (mostly low GPA issues)
- I want to turn a Boost SMPS into the simplest audio power amplifier.
I'm trying to turn a Boost into a Flyback and then into an audio amplifier Basically I wanted a simple SMPS modulated with an audio signal I know, you will say that the class D amplifier is also an SMPS, but the class D amplifier needs at least 2 power transistors + a large
- Providing the earth ground to the DC output of SMPS
Prior to making a solid connection between the SMPS negative output terminal and "actual earth ground " I suggest measuring the voltage between those two points
- Designing flyback transformer for SMPS | All About Circuits
hello, I was trying to build SMPS using switching ic's UC3845 or HVLED007 but ending with less current delivery or poor power factor might be due to improper flyback transformer design the thing is i don't have the bobbin , core datasheet were i can get all the specs currently i have
- SMPS circuit for LTspice - All About Circuits
Hi, I'm searching for an example circuit to be run on LTSpice with a SMPS together with a common mode choke The idea is to run a transient simulation in order to see the effect of this latest component on output voltage (noise reduction) Do you have anything to suggest? Thank you

USB Charger (and SMPS) AC Leakage Experiment To confirm my beliefs and to correct some erroneous information presented in this post My Mobile Charger Shocked Me While Charging, and other posts in this forum, I conducted an experiment Call it put up or shut up Belief #1 USB chargers and by
- SOLVED - SMPS - UC3842 ULVO issue - All About Circuits
Background I'm repairing a monitor with a SMPS utilizing a UC3842 IC I've tested the monitor in my shop and worked fine When I get to the customer's site, it wouldn't startup The difference is the input AC (My shop = 120 to 130 VAC He's shop is 118VAC) At his site, I tested the Vcc
