Campbell Collins Introduces Range of TO-220 Footprint Compatible Switching Regulators delivering up to 1A
Campbell Collins Ltd, a specialist supplier of power supplies, capacitors and hi-rel power semiconductors, is pleased to announce the availability of a range of TO-220 footprint compatible switching regulators from Arch Electronics, which offer customers an ultra high efficiency alternative to LMxx Linear Regulator devices.
The The SR78/1000 series come with Over Current Protection, Short Circuit Protection and Over Temperature Protection as standard, and are housed in a UL94V-0 rated package. Operating temperature range is -40°C to +85°C, and storage temperature range is -55°C to +125°C, making the devices suitable for a wide range of demanding applications. Typically, derating is not necessary unless operating above 60°C, and so the power density of the devices is as high as 280W/in3. The MTBF figure is in excess of 5Mhrs, and they come with a 2 year manufacturer’s warranty.
“The SR78/1000 series offers our customers an ultra high efficiency alternative to unreliable, inefficient Linear Regulators” said Phil Goff, Sales & Marketing Manager for Campbell Collins. “Having the opportunity to improve their systems’ reliability without the need for a board redesign is a huge benefit to the customer” he continued.
