CUI’s Power Group has introduced four new series to the non-isolated DC switching regulators lineup. The lineup now includes next-gen models in the series namely VX78-500, VX078-500, VX78-1000, and VX078-1000. These are extremely efficient, typically up to 96% and balance maximizing economy while delivering a high level of performance as a direct alternative to using linear regulators.
Owing to the switching technology, these models are footprint compatible with TO-220 package LM78XX and LM79XX model regulators. Unlike the linear regulators, these don’t require a heat sink and hence these are ideal for portable devices, battery-fed equipment, and embedded designs where energy efficiency is a prime concern.

Both, the encapsulated VX78 Series and open frame VX078 Series, offer 500 mA and 1A output current as low as 0.2 mA. Further, these are packed in an ultra-compact 3 pin SIP footprint. Dimensionally, the former ones measure 0.45 x 0.29x 0.40 inches while the latter have smaller dimensions of 0.39 x 0.28 x 0.43 inches.
Moving on, the 500 mA series accept a wide range of input voltages up to 4.75 to 36 Vdc, while the 1 A series accommodate input voltage ranges up to 6 to 36 Vdc. The available nominal output voltages include 3.3, 5, 9, 12, and 15 Vdc, whereas the operating temperatures for all models range from ‑40 up to +71°C at full load, derating to 60% load at +85°C.
• low ripple and noise
• continuous short circuit protection
• UL 60950‑1 and CSA safety certifications, along with the CE mark
• minimum MTBF of 2,000,000 hours at +25°C ambient
The VX78-500, VXO78-500, VX78-1000, and VXO78-1000 series are available immediately with prices starting at $2.09 per unit at 100 pieces through distribution.
