Efficient 1.5 A Switching Regulator

Mon, 12/13/2010 - 3:14pm
CUI Inc's power line, V-Infinity, and their distributor Digi-Key Corporation, announced the addition of a 1.5 A model to their V78XX switching regulator series. With this latest addition, CUI now offers 0.5 A, 1 A, 1.5 A, and 2 A switching regulators to meet a wide variety of power needs. The compact V78XX-1500 series has been designed to be a high performance alternative to linear regulators. Unlike linear regulators, this 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-1500 series has efficiencies up to 95% in a compact SIP package measuring 11.50 x 9.00 x 17.50 mm. Units are pin out compatible with industry standard LM78XX linear regulators and come in both straight and right angle pin configurations.

This series has a wide input range available from 4.75 to 18 Vdc and regulated output voltages of 2.5, 3.3, 5, and 6.5 Vdc. Operating temperature range of -40° to +85°C at 100% load. The non-isolated converters offer short circuit protection, thermal shutdown, very low ripple and noise, and an MTBF of 2 million hours.

The V78XX-1500 series switching regulators are available now through Digi-Key and start at $6.79 per unit at 1000 pieces.
