50-W DC-DC CONVERTERS RAISE THE POWER-DENSITY BAR

摘要

Wall Industries' latest generation of dc-dc power converters delivers 50 W of continuous output power in 2.0- by 1.0-by 0.4-in. encapsulated, shielded metal packages. The DH50 series comprises 3.3-, 5-, 12-, and 15-V dc single-output models that operate over 2:1 input voltage ranges of 9 to 18, 18 to 36, and 36 to 75 V dc. An advanced circuit topology delivers up to 92% efficiency. Operating temperature ranges from -40℃ to 80℃. Other features include remote on/off control, trimmable output voltage, under-voltage lockout, and 1500-V dc I/O isolation.
