The TBA 1-0521E is a dual output, isolated DC/DC converter manufactured by TRACO Power. It is encapsulated in a single-in-line package (SIP-7) with a total power rating of 1 W. The two outputs are +5 Vdc and -5 Vdc, respectively. It is designed to provide regulated, isolated DC voltage from a single input source and is commonly used in distributed power architectures, low-profile system designs, and noise-sensitive applications. It provides excellent load and line regulation, good noise immunity, and low temperature coefficient. Its compact size, high efficiency, and cost-effectiveness makes it an ideal choice for many applications.
