Simple dual constant-current load tests low-current power supplies
by John S Lo Giudice, STMicroelectronics, Schaumburg, IL; Edited by Charles H Small and Fran Granville, EDN, Jun 21 2007
Focus:
An electronic load built using a simple circuit can be used to test power supplies with 50-mA to 1-A output. This test circuit provides greater accuracy than higher-power, off-the-shelf loads and offers a less-cumbersome alternative to resistive loads.
What you’ll learn:
- How to test low-current switched-mode power supplies
- How to build a low-current, battery-powered electronic load
