Press Release Summary:
Measuring 15.24 x 8.50 x 7.00 mm, compact V78XX-500-SMT series offers efficiencies of up to 96% and does not require heat sink. It offers wide input range from 4.5-28 Vdc and regulated output voltages of 3.3, 5, 12, and 15 Vdc. Output current is 500 mA with operating temperature range of -40 to +71Â°C at 100% load, derating to 60% load at 85Â°C. Other features include short circuit protection, thermal shutdown, low ripple and noise (10 mV p-p typical), and MTBF of 2 million hr.
Original Press Release:
SMT DC Switching Regulator Is Highly Efficient
June 16, 2009
V-Infinity, a division of CUI Inc, announces the release of the V78XX-500-SMT series, a surface mount version of its 0.5 A V78XX-500 dc switching regulator. The V78XX-500-SMT offers efficiencies of up to 96% and is designed to be a high performance alternative to linear regulators. Unlike linear regulators, the V78XX-500-SMT series does not require a heat sink, making it ideal for applications where board space is at a premium and energy efficiency is a concern.
The V78XX-500-SMT series is compact, measuring 15.24 x 8.50 x 7.00 mm. A wide input range is available from 4.5 to 28 Vdc and regulated output voltages of 3.3, 5, 12, and 15 Vdc are offered. Output current is 500 mA with an operating temperature range of -40 to +71°C at 100% load, derating to 60% load at 85°C. The converters offer short circuit protection, thermal shutdown, very low ripple and noise (10 mV p-p typical), and an MTBF of 2 million hours. The V78XX-500-SMT series switching regulators are available now through Digi-Key and start at $8.24 for 1 piece. Please contact CUI directly for OEM quantities.
