Beta Dyne is protected under various patents, including but not limited to U.S. Patent numbers: 5,777,519; 6,188,276; 6,262,901; 6,452,818; 6,473,3171.
Functional Description
The Q25 series is a 25-30W low noise isolated converter, consisting of 14 standard single & dual output models from 3.3VDC to 15 VDC and 4:1 input
voltage range from 9V to 72V. Output synchronous rectification followed by a very low dropout linear regulator made possible to achieve up to 87% efficiency and less than 5mV output noise with external
capacitors. Standard features include input under
voltage protection , external synchronization and thermal protection. The converter is packaged in a 1 x 2 x .45’’ metal case with six-sided shielding.
