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 undervoltage protection , external synchronization and thermal protection.
The converter is packaged in a 1 x 2 x .
45’’ metal case with six-sided shielding.
