Switching Regulator Needs No Heat Sink

Thu, 08/19/2010 - 9:20am

V78XX-2000V-Infinityannounced the addition of a 2-A model to their V78XX switching regulator series.  The compact V78XX-2000 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-2000 series has efficiencies up to 92% 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 is from -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-2000 series switching regulators are available now through Digi-Key and start at $7.46 per unit at 1000 pieces.  Contact CUI directly for OEM pricing.
