Max Power Reinforced Insula
The InQor half-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.

BASIC OPERATION AND FEATURES
CONTROL FEATUR
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 (2): The F inp, Pin 2, permits
the user to control when the convern or off. This input
is referenced to returterminal ohe input s, Vin(-).
The ON/OFF sigtive low (eaning that a low turns the
converter o). Figuails fouossible cor driving
the ON/OFF p. Figurdetailed look of t/
OFF ccuitry.
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 effici
even at very low output voltages and very high output current
REMSENSE(+) Pins 7 and 5): NSE(+) inputs
correcltage dros along the nductoconnthe
converteut pins to the load.

APPLICATION CONSIDERATIONS
Input System Instability: This condition can occur because
any dc-dc converter appears incrementally as a negative
resistance load. A detailed application note titled “Input
System Instability” is available on the SynQor website which
provides an understanding of why this instability arises, and
shows the preferred solution for correcting it.

Application Circuits: Figure D provides a typical circuit

Input Filtering and External Capacitance: Figure E provides

dramatically reduces input terminal ripple current, which other
