This board demonstrates an isolated, high-efficiency synchronous buck converter switch-mode power supply (SMPS) using the world’s smallest isolators, NVE IsoLoop® MSOP Isolators.
The output is 3.3V at 750 mA.
The board has three channels of isolation to ensure the output is electrically isolated from the input. A two-channel MSOP-8 isolator isolates synchronous rectification and a single-channel MSOP-8 isolator isolates output-voltage feedback. MSOP isolators minimize board area.
Despite the compact components, the board has full 2.5 kV isolation and maintains 3 mm creepage.
Board dimensions are approx. 2 in. by 0.5 in. |
