  • Measuring DC-DC converter Efficiency

    This blog is about my test rig for measuring DC-Dc converter efficiency in the range Vin/Vout 2-50V and Iin/Iout 1-10A. It can also be used to measure the power consumption of DC systems in same range. The test rig ready to run (power supply and device…

  • An isolated low noise +/-5V DC power supply

    Introduction I’m working on test rig for accurately measuring the efficiency of DC-DC regulators or converters. It uses 2 precision current shunts to measure the input and output current. These need very low noise pre-amplifiers which must each be powered…

  • Silent Switcher - LT8640s meets KiCad

    The first part of this project kicked off with a blog “First Design with KiCad (8.0)” about 4 weeks ago. The idea was to build a replacement for obsolete TO3 can linear voltage regulators using the Linear Technologies (now owned by Analog Devices) LT8640s…

  • Does anyone knows. How a duracell powercheck feature works ?

    Does anyone knows. How a duracell powercheck feature works. I need complete detail about it. like what is the current consumption, resistance of the strip etc.

  • First Design with KiCad (8.0)

    I’ve been using the same PCB design software for over 20 years (Easy PC) and it’s served me well during that time. It’s had an update pretty much every year and it can still load files from 20 years ago. It hardly ever crashes and I’ve probably designed…

    ANP117 | Impact of output capacitor on feedback loop stability of a power supply

    APPLICATION NOTE Impact of output capacitor on feedback loop stability of a power supply ANP117 by Eleazar Falco 1. INTRODUCTION AND THEORETICAL BACKGROUND A switching power supply requires one or more capacitors across the output voltage rail…

  • Maintain power long enough for SBC to power down

    Hello, I have connected my 3D printer to an Orange Pi Lite running Octoprint as it is much more user friendly when it comes to managing my prints. This works just fine but required an additional power source and so I opened the printer and connected…

  • LED Worklight and teardown

    My workshop areas have eight 4 foot double tube fluorescent worklights in the man-cave. I installed the 4 foot floursecent fixtures 35 years ago. As the tubes fail, they get consolidated, and one by one empty fluorescent fixtures get replaced with LED…

  • Single Phase to three signal generator.

    Hello everyone, I am designing a low voltage power supply that will run single phase to three phase circuit and will be using ultrosonic frequency as its signal input. The current circuit design uses three operational amplifiers that has a 60 degress…

  • Heatsinks

    Recently /members/andrewj posted about some issues with heatsinks. It so happened that he was thinking of using heatsinks similar to one I'd already chosen for a resistor based adjustable load. I'd run into some issues using active loads with a power…

  • Inaccurate Readings from Thermal Imaging Camera on Copper Heatsink-Anyone Else Had this Happen?

    I have a Fluke Ti25 Thermal Imaging Camera that I used on a 1,200 watt PFC Controller to measure the power FET and power diode temps. The Fluke camera has an adjustment for emissivity, which I set to copper (I don't recall the value). I chose this as…
