This document details the MAXREFDES128# subsystem reference design, a 36V to 57V input, 5V output, no-opto flyback isolated power supply capable of 12.5W. Design files and test results are included. Hardware is available for purchase.

MAXREFDES1105: Small, 90.4% efficient, 5V/2A, synchronous, optocouplerless flyback DC-DC converter with MAX17690 and MAX17606

Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.

Contactless, precision AC current sensing using Hall Effect sensors

This TI design uses Hall sensing technology from Texas Instruments (TI) to provide a solution for understanding the AC current flowing through a wire without any physical intervention. The TIDA-00218 uses a flux concentrator to concentrate the magnetic flux around the AC current-carrying wire without allowing it to escape into the air, and then directs this magnetic flux to the Hall sensor.
