8:1 input 100 W DC/DC in quarter brick format

Flex Power Modules has added a quarter brick, baseplate-cooled DC/DC to their product line-up, featuring an ultra-wide 9-75 VDC input range (100V/100 ms). The PKM8100A delivers 100 W at up to 89% efficiency and is available with initial outputs of 12 V/ 8.35A or 54 V/1.85 A.

Input to output isolation rating is 3000 VDC, meeting the requirements of IEC/UL 62368-1. The product is fully featured with remote control, output trim and remote sensing, while protection includes over-temperature, input under-voltage lockout and output over-voltage and short circuit.

The PKM8100A is presented in the industry-standard quarter brick format, 57.9 x 36.8 x 12.7 mm with through-pin connections. The device operates to a maximum baseplate temperature of 110°C, allowing operation without derating to 85°C ambient with 3 m/s airflow or to 75°C ambient with natural convection when fitted to a cold wall.

Class B of EMC standards EN 55032, CISPR 32 and FCC part 15J are met with an external input filter with component values specified in the technical specification. Reliability of the parts is high at 3.78 Mhrs according to Telcordia SR-332 standard, issue 3 method 1, at 40°C ambient.

“The PKM8100A expands our range of quarter brick DC/DCs” comments David Xie, Director R&D and Product Management in Shanghai of Flex Power Modules. “The ultra-wide input range means that the part can ride through dips and surges in tough environments, or one part can cover a range of nominal inputs, reducing inventory holding”.

The PKM8100A series is available for sampling now, and will be released for production in December.
