QFN-based package technology provides superior thermal performance, eases electrical debugging and improves manufacturability with higher assembly yield and the ability to visually inspect solder joints. At 50°C with no airflow, no thermal de-ratings are required for output voltages of 1.8V and below.
“Delivering 20A from a 12V supply in a 12x14x4mm module sets this device apart in the market,” said Jon Cronk, Marketing Director, Power Management Products, Exar. “By optimising efficiency, size and thermal performance, the XR79120 boasts the best power density available since the big bang.”
The XR79120 will be available in a RoHS compliant, halogen free, space-saving 74-pin 12x14x4mm QFN package. The XR79120 is priced at $13.95 in 1,000-piece quantities.
