BASIC OPERATION AND FEATURES
The MQHR DC/DC converter uses a two-stage power
conversion topology. The first, or regulation, stage is a
buck-converter that keeps the output voltage constant over
variations in line, load, and temperature. The second, or
isolation, stage uses transformers to provide the functions of
input/output isolation and voltage transformation to achieve
the output voltage required.
The MQnvertes control cdoes n
over-tee shutdow
In the dual output converter there are two secondary
windings in the transformer of the isolation stage, one for
each output. There is only one regulation stage, however,
and it is used to control the positive output. The negative
output therefore displays “Cross-Regulation”, meaning tha
its output voltage depends on how much current is draw
from each output.

SHUT DOWN: The MQHR converter will shut down in
response to only five conditions: ENA input low, VIN input
below under-voltage shutdown threshold, VIN input above
over-voltage shutdown threshold, output voltage below the
output under-voltage threshold, and output voltage above
the output over-voltage threshold. Following any shutdown
event, there is a startup inhibit delay which will prevent the
converter from restarting for approximately 100ms. After
the 100ms delay elapses, if the enable inputs are high and
the input voltage is within the operating range, the converter

SYNCHRONIZATION: The MQHR converter’s switching
frequency can be synchronized to an external frequency
source that is in the 500 kHz to 700 kHz range. A pulse
train at the desired frequency should be applied to the SYNC
IN pin (pin 6) with respect to the INPUT RETURN (pin 2).
This pulse train should have a duty cycle in the 20% to 80%
range. Its low value should be below 0.8V to be guaranteed
to be interpreted as a logic low, and its high value should
be above 2.0V to be guaranteed to be interpreted as a logic
high. The transition time between the two states should be
less than 300ns.

Application Section
INPUT UNDER-VOLTAGE SHUTDOWN: The MQHR
converter has an under-voltage shutdown feature that
ensures the converter will be off if the input voltage is too
low. The input voltage turn-on threshold is higher than
the turn-off threshold. In addition, the MQHR converter
will not respond to a state of the input voltage unless it
has remained in that state for more than about 200µs. This
hysteresis and the delay ensure proper operation when the
source impedance is high or in a noisy environment.

CURRENT LIMIT: In the event of excess load, the MQHR
converter will quickly reduce its output voltage to keep
the load current within safe limits (see Figure 12). If the
overload persists for more than 14 milliseconds, the converter
will shut off, wait a restart delay, and then automatically
attempt to re-start. The timeout is internally implemente
with an integrator: counting up whenever current limit
active, and counting down at 1/5th the rate whenever curren
limit becomes inactive. In this way a series of short-ation T SYSTEM INSTABThition can occur
