Flex Announces PKU4116HD Series 1 / 16th Brick DC / DC Converter for RFPA and PoE Applications – EEJournal
Flex Power Modules presents its PKU4116HD through-hole DC / DC converter, with 36-60 V input (80 V peak) and fully regulated 55 V output. The open frame module is the industry standard 1 / 16th brick format, 33.02mm x 22.86mm x 9.8mm, and is rated at 110W / 2A at an ambient temperature of 50 ° C with natural convection and at 85 ° C with additional air flow. Excellent thermal performance also allows operation at 100 ° C ambient with derating. Efficiency is high, typically 92.4% at 48 Vin, full load and proven technology are used to provide high reliability at an attractive price.
The PKU4116HD features monotonic starting in a pre-polarized load, remote control function and full protection against overheating, input undervoltage, output overvoltage and overcurrent. Standby power is typically 0.5 W.
Input / output insulation is 2250VDC and conforms to IEC / EN / UL 62368-1. Together with the 55V output, this makes the room particularly suitable for Power over Ethernet (PoE) applications as well as a power supply for RF power amplifiers in microwave radio systems and small cells. The conducted EMC levels EN 55022/32, CISPR 22 and FCC part 15J can be achieved with a simple network of external filters.
The PKU4116HD is suitable for pin-in-paste reflow processes for convenient automated assembly.
David Xie, Director of R&D and Product Management at Flex Power Modules, comments:
“This new sixteenth brick DC / DC is a great addition to our line with its very competitive price. It is ideal for PoE applications and price sensitive cellular base stations ”.
