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 ON/OFF input, Pin 2,
permits the user to control when the converter is on or off.
This input is referenced to the return terminal of the input
bus, Vin(-). The ON/OFF signal is active low (meaning that
a low turns the converter on). Figure A details four possible
circuits for driving the ON/OFF pin. Figure B is a detailed
look of 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.
These converters are offered totally encased to withstand
harsh environments and thermally demanding applications.
Dissipation throughout the converter is so low that it does
not require a heatsink for operation in many applications;
however, adding a heatsink provides improved thermal
derating performance in extreme situations.
This series of converters uses the industry standard footprint
and pin-out configuration.
REMOTE SENSE(±) (Pins 7 and 5): The SENSE(±) inputs
correct for voltage drops along the conductors that connect
the converter’s output pins to the load.
Pin 7 should be connected to Vout(+) and Pin 5 should
be connected to Vout(-) at the point on the board where
regulation is desired. A remote connection at the load can
adjust for a voltage drop only as large as that specified in
this datasheet, that is
[Vout(+) - Vout(-)] – [Vsense(+) - Vsense(-)] ≤
Sense Range % x Vout
Pins 7 and 5 must be connected for proper regulation of
the output voltage. If these connections are not made,
the converter will deliver an output voltage that is slightly
higher than its specified value.
Note: The output over-voltage protection circuit senses the
voltage across the output (pins 8 and 4) to determine when
it should trigger, not the voltage across the converter’s
sense leads (pins 7 and 5). Therefore, the resistive drop on
the board should be small enough so that output OVP does
not trigger, even during load transients.

Application Section
OUTPUT VOLTAGE TRIM (Pin 6): The TRIM input permits
the user to adjust the output voltage across the sense leads up
or down according to the trim range specifications.
To decrease the output voltage, the user should connect
a resistor between Pin 6 and Pin 5 (SENSE(-) input). For a
desired decrease of the nominal output voltage, the value
of the resistor should be
Rtrim-down =
(
90.9
Δ%
- 0.909
)
(kΩ)
where
Δ% =
|
Vnominal – Vdesired
Vnominal
| x 100%
To increase the output voltage, the user should connect a
resistor between Pin 6 and Pin 7 (SENSE(+) input). For a
desired increase of the nominal output voltage, the value of
the resistor should be:
Rtrim-up =
(
100+Δ%
Δ%
)(
Vnom
- 0.909
1.225
) (kΩ)
where:
Vnom = Nominal Output Voltage
Graphs show the relationship between the trim resistor
value, Rtrim-up and Rtrim-down.This shows the total range
the output voltage can be trimmed up or down.
Note: The TRIM feature does not affect the voltage at
which the output over-voltage protection circuit is triggered.
Trimming the output voltage too high may cause the overvoltage protection circuit to engage, particularly during
transients.
It is not necessary for the user to add capacitance at the
Trim pin. The node is internally bypassed to eliminate noise.
Total DC Variation of Vout: For the converter to meet its full
specifications, the maximum variation of the dc value of VOUT,
due to both trimming and remote load voltage drops, should
not be greater than that specified for the output voltage trim
range.

Protection Features
Input Under-Voltage Lockout: The converter is designed
to turn off when the input voltage is too low, helping avoid
an input system instability problem, described in more detail
in the application note titled “Input System Instability”
available on the SynQor website. The lockout circuitry is a
comparator with DC hysteresis. When the input voltage is
rising, it must exceed the typical Turn-On Voltage Threshold
value (listed on the specification page) before the converter
will turn on. Once the converter is on, the input voltage
must fall below the typical Turn-Off Voltage Threshold value
before the converter will turn off.
Output Current Limit: The maximum current limit remains
constant as the output voltage drops. However, once the
impedance of the load across the output is small enough to
make the output voltage drop below the specified Output
DC Current-Limit Shutdown Voltage, the converter turns off.
The converter then enters a “hiccup mode” where it
repeatedly turns on and off at a 4 Hz (nominal) frequency
with a 20% duty cycle until the short circuit condition is
removed. This prevents excessive heating of the converter
or the load board.
Output Over-Voltage Limit: If the voltage across the
output pins exceeds the Output Over-Voltage Protection
threshold, the converter will immediately stop switching.
This prevents damage to the load circuit due to 1) excessive
series resistance in output current path from converter
output pins to sense point, 2) a release of a short-circuit
condition, or 3) a release of a current limit condition. Load
capacitance determines exactly how high the output voltage
will rise in response to these conditions. After 200 ms the
converter will automatically restart.
Over-Temperature Shutdown: A temperature sensor
on the converter senses the average temperature of the
module. The thermal shutdown circuit is designed to turn the
converter off when the temperature at the sensed location
reaches the Over-Temperature Shutdown value. It will allow
the converter to turn on again when the temperature of the
sensed location falls by the amount of the Over-Temperature
Shutdown Restart Hysteresis value.

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.
Input Filtering and External Capacitance: Figure
D provides a diagram showing the internal input filter
components. This filter dramatically reduces input terminal
ripple current, which otherwise could exceed the rating of
an external electrolytic input capacitor. The recommended
external input capacitance is specified in the Input
Characteristics section on the Electrical Characteristics page.
More detailed information is available in the application note
titled “EMI Characteristics” on the SynQor website.
Application Circuits: Figure C provides a typical circuit
diagram which details the input filtering and voltage
trimming.

Application Section
Startup Inhibit Period: The Startup Inhibit
Period ensures that the converter will remain off for
approximately 200 ms when it is shut down for any
reason. When an output short is present, this generates
a 4 Hz “hiccup mode,” which prevents the converter from
overheating. In all, there are six ways that the converter
can be shut down, initiating a Startup Inhibit Period:
• Input Under-Voltage Lockout
• Output Over-Voltage Protection
• Over Temperature Shutdown
• Current Limit
• Short Circuit Protection
• Turned off by the ON/OFF input
Thermal Considerations: The maximum operating baseplate temperature, TB, is 100 ºC. As long as the user’s
thermal system keeps TB ≤ 100 ºC, the converter can deliver
its full rated power.
A power derating curve can be calculated for any heatsink
that is attached to the base-plate of the converter. It is only
necessary to determine the thermal resistance, RTHBA, of the
chosen heatsink between the base-plate and the ambient air
for a given airflow rate. This information is usually available
from the heatsink vendor. The following formula can then
be used to determine the maximum power the converter
can dissipate for a given thermal condition if its base-plate
is to be no higher than 100 ºC.
The Startup Inhibit Period graph shows three turn-on
scenarios, where a Startup Inhibit Period is initiated at t0,
t1, and t2:
Before time t0, when the input voltage is below the UVL
threshold, the unit is disabled by the Input Under-Voltage
Lockout feature. When the input voltage rises above the
UVL threshold, the Input Under-Voltage Lockout is released,
and a Startup Inhibit Period is initiated. At the end of this
delay, the ON/OFF pin is evaluated, and since it is active,
the unit turns on.
At time t1, the unit is disabled by the ON/OFF pin, and it
cannot be enabled again until the Startup Inhibit Period has
elapsed.

P diss
=
100 ºC - TA
RTHBA
This value of power dissipation can then be used in
conjunction with the data shown in Figure 2 to determine
the maximum load current (and power) that the converter
can deliver in the given thermal condition.
For convenience, Figures 3 and 4 provide Power derating
curves for an encased converter.
When the ON/OFF pin goes high after t2, the Startup Inhibit
Period has elapsed, and the output turns on within the
typical Turn-On Time.
