Extended Input Military Hi-Rel 28V DC/DC Converter

SR announces the new MQFL-28V product family to its portfolio of Hi-Rel dc/dc converters. This is the only wide range input dc/dc converters developed specifically for the Military/Aerospace industry. To ensure survivability in the most

hostile environments, the MQFL-28V series of 100W dc/dc converters is housed in full size (FL) packages usingSR's innovative QorSeal packaging technology which includes tin whisker mitigation.

While the MQFL-28V accepts continuous input voltages of 16-40V, it is capable of handling transient input voltages of 5.5-50V @ 1 second. The MQFL-28V family incorporates a special "boost-converter" stage that permits the converters to deliver full power through transients where its input voltage falls to as low as 5.5V. The under-voltage transient profile is designed to comply with all initial engagement surges, starting or cranking voltage transients, and under-voltage surges specified in MIL-STD-704-8 (A through F), RTCA/DO-160E, MIL-STD-1275B and DEF-STAN 61-5 (Part 6)/5 (operational portions).

The MQFL-28V converters provide up to 100 W of power and are now available with single output voltages of 3.3V, 5V, 12V and 28V. Additional single output voltage versions include 1.5V, 1.8V, 2.5V, 6V, 7.5V, 9V and 15V.
