DC-DC Converter
Continuous Input Transient Input
The InQor quarter-brick converter series is composed
of next-generation, board-mountable, isolated, 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.
Operational Features
• High efficiency, 85% at full rated load current
• Delivers full power with minimal derating - no heatsink required
• Operating input voltage range: 9-75V
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
Mechanical Features

BASIC OPERATION AND FEATURES
CONTROL FEATURES
This converter series uses a two-stage power conversion
topology. The first stage is a buck-converter that keeps the
output voltage constant over variations in line, load, and
temperature. The second stage uses a transformer to provide
the functions of input/output isolation and voltage step-up or
step-down to achieve the output voltage required.
REMOTE ON/OFF (Pin 2): The input, Pin 2, permits
the user to control when the convertor off. This input
is referenced to the return nal of put bus, Vin(-).
The ON/OFF signal is active laning low turns the
converter on). Figure A etails fsible cuits for driving
the ON/OFF pin. Figure B is a detaof the internal ON/
OFF circuitry.
Both the first stage and the second stage switch at a fixed
frequency for predictable EMI performance. Rectification of
the transformer’s output is accomplished with synchronous
rectifiers. These devices, which are MOSFETs with a very low
on-state resistance, dissipate far less energy than Schottky
diodes. This is the primary reason that the converter has such
high efficiency, even at very low output voltages and very high
output currents.

a heatsink provides improved thermal derating peormance in
extreme situations.

Pins 7 and 5 ust onnected fproper regulation of
thoutput voltag. If connections are not made, the
converter will deliver an ovoltage that is slightly higher
than its d value.
This series of converters use the industry standard footp
pin-out configuration.
Note: the outr-voltage protection circuit senses the

it should trigger, not e voltage across the converter’s sense
