This document describes the features and characteristics of MPS's new A-Series DC/DC converters, including low cost, high reliability, SMT-on-pcb construction, wide input voltage ranges, small packages, etc.
The BWR series offers 15‑20 W dual‑output DC/DC converters with selectable output voltages of ±5 V, ±12 V or ±15 V. They feature ultra‑wide input ranges, high efficiency, and full 1500 Vdc isolation, making them suitable for high‑volume OEM applications in telecom, computer, and instrumentation markets.
The datasheet includes detailed electrical specifications, mechanical dimensions, protection functions, trimming options, and soldering guidelines. It also outlines quality‑assurance processes such as HALT testing and compliance with UL/EN standards.
