DATELs new 3.6-10W UNR SM Series consists of non-isolated, 5V-to-1.8V (2A), 5V-to-2.5V (2A), 5V-to-3.3V (3A), and 12V-to-3.3V (3A) DC/DC converters in miniature, 1" x 1" surface-mount packages. The "gull-wing" packages (with metal shells and non-conductive plastic baseplates) weigh a mere 17 grams and can withstand temperatures up to +235°C. They are compatible with virtually all contemporary pick-and-place and solder-reflow processes.
