Typical PCB Mount Applications

The PCB terminal option allows mounting on an industry standard printed circuit board, with two different pin lengths. Vicor offers a

variety of downstream DC-DC converters driven by the 48V output of the PFM in a VIA package. The 48V output is usable directly by loads

that are tolerant of the PFC line ripple, such as fans, motors, relays, and some types of lighting. Use downstream DC-DC Point of Load

converters where more precise regulation is required.
