Sixteenth DC-DC brick provides 100W up to 30V input
14-04-2022 | Flexible Power Module | Able
Flex Power Modules now offers its PKU-D series of low profile sixteenth brick DC-DC converters with the PKU3913D, a 100W rated part with an extended input range down to 30V and a regulated output of 12V /8.3 A. The intended application is for nominal 48V or 54V inputs with possible long cable lengths and consequent voltage drops, including microwave radio links. In this case, the low input dropout voltage of the part is an advantage to guarantee long operation, and the input range is also compatible with the PoE standard IEEE 802.3af (37-57VDC).
The PKU3913D is developed for high efficiency at lower input voltages, peaking at over 95%. Per Telcordia standards, the parts exhibit pre-bias, monotonic start capability, remote on/off, and an MTBF of 13.88 million hours at 40°C ambient. The products are IEC/EN/UL 62368-1 certified for 2250VDC input-output isolation. Full protection is included against overheating, input undervoltage, output overvoltage, overcurrent and short circuit.
The series is housed in a 33.02mm x 22.86mm footprint and stands just 11.3mm tall in open frame formats, with optional through-hole or SMT termination, or just 12.7 mm high for the pinned version with an optional base plate. Size and pinout conform to industry standards.
The series benefits from this long experience and has undergone comprehensive qualification, which guarantees reliable operation as well as highly automated manufacturing. Its products are backed by ISO 9001/14001 certification and excellent technical support.
