Murata BWR-5/6-3.3/7-D12/D24/D48 Dual Output 33W DC/DC Converter Handbook
The BWR‑5/6‑3.3/7‑D12/D24/D48 family delivers up to 33 W of combined power from two regulated outputs (5 V @ 6 A, 3.3 V @ 7 A). The converters are fully isolated (1500 VDC), operate from 10‑75 V input ranges, and meet UL1950, EN60950‑1 and IEC950 safety standards. They feature no‑load operation, continuous short‑circuit protection, over‑voltage/under‑voltage shutdown, thermal shutdown, and optional on/off control.
The handbook includes an ordering guide, pin‑out diagram, performance curves, and detailed specifications such as efficiency, ripple, and temperature limits. It also describes optional functions like output trimming and external capacitor recommendations, as well as protection mechanisms and mechanical dimensions of the 2" × 2" × 0.45" metal case.
