The InQor
®
full-brick converter series is composed of next-
generation, board-mountable, isolated (REINFORCED
INSULATION),
fixed switching frequency dc-dc
converters that use synchronous rectification to achieve
extremely high power conversion efficiency. Each module
is supplied completely encased to provide protection
from the harsh environments seen in many industrial and
transportation applications.

Note 1: Output is terminated with 1 µF ceramic and 15 µF low-ESR tantalum capacitors. For applications requiring reduced output voltage ripple and
noise, consult SynQor applications support (e-mail: support@synqor.com)
Note 2: Trim-up range is limited below 10 % at low line and full load.
Note 3: Maximum Trim-up is 10 %. Applying more than 6.2 V between trim pin and Vout(-) may damage the unit.
Note 4: Safety certification requires the use of a fuse rated at or below this value.
