RD9Z1-638-12V is a battery management system designed to demonstrate the capabilities of the MM9Z1J638 battery sensor IC in 12 V lead-acid applications where high EMC performance is required to obtain high-precision measurements of critical battery parameters.
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.
