DESCRIPTION:
The DHC2800S series of DC-DC converters provides the ruggedness, reliability and features required to
meet the advanced design challenges of today's hi-rel market. This is accomplished while retaining a
power density of 17 W/in³ and 425 mW/gram of power/package performance. The use of advanced
substrate and reflow soldering techniques during construction results in a rugged, cost-effective and com-
pletely solderable package.
DHC2800S hybrid converter series utilizes all ceramic capacitors and surface mount magnetics to
provide reliable operation at all operating temperatures while surviving very high G forces.
DHC2800S standard features include output fault monitoring and/or turn on voltage point programming
via the shutdown pin. All three functions may be implemented simultaneously with a minimum of external
components. An output voltage adjustment/load compensation pin is also standard.
Fault tolerant design protects these converters from most external circuit faults. The output and output
adjust pins will withstand +35V while the shutdown pin will withstand +50V protecting the converters
from a variety of system or board faults i.e. solder bridges, etc. Unique load fault protection circuitry
allows this converter to pull up loads having difficult static load line characteristics and allows short term
load excursions significantly beyond ratings in most applications.
A transformer isolated forward converter topology operating at a switching frequency of 400kHz allows
operation over a wide input voltage range. Internal filtering of both input and output eliminates the need for
external capacitors in many applications.
The 8-pin DIP package is hermetically sealed and isolated from the internal circuits. Heat sinking is
recommended for full power operation at elevated ambient temperatures.

APPLICATION NOTES
POWER SUPPLIES
LOAD FAULT RESPONSE
The DHC2800S series of dc-dc converters share load fault
philosophies. Load fault conditions include short-circuit and
severe overload conditions. The DHC2800S converter series
responds to load faults by turning off all power conversion cir-
cuits for 250mS and then attempting to restart for 10mS (typi-
cal). The net "on" duty factor during a fault is very low result-
ing in low converter dissipation and immunity from overheating
at 125ꢀC. Current beyond rated can flow into the load at
startup time. This allows the converter to bring up capacitive
and other difficult load types more reliably than competing con-
verters.
The output voltage of the DHC2800S may be adjusted from
90% to 110% of nominal value by the use of a 50KΩ potenti-
ometer as shown. Adjustment beyond this range is possible
however certain characteristics of the converter such as but
not limited to input voltage range, efficiency, ripple and tem-
perature performance will change. Characterization by the user
is recommended in such applications.
Adjust/comp (pin 3) may be driven by external circuitry refer-
enced to pin 2 (-output) if desired. Grounding pin 3 causes
voltage to increase (25% typically) while driving pin 3 above
1.3V causes output voltage to decrease. Pin 3 may be driven
through 10KΩ or more if connection of the comp function is
also required.
The comp function of pin 3 allows capacitive loads as large
as 1000µF to be accommodated on the DHC2805S without
loss of stability. This feature may be utilized by connecting a
10nF capacitor between pins 3 and 1. This is generally recom-
mended when low ESR load capacitances of 100µF or greater
are used.
SHUTDOWN PLUS
Pin 5 is used for remote shutdown, output fault detection,
and/or setting the input voltage point at which the converter
will turn on as shown in the typical application diagram. No
connection to pin 5 is necessary for normal operation of the
converter. Pin 5 is referenced to the -input (pin 7).
Shutdown may be implemented by simply connecting pin 5
to an open collector logic output or switch rated at 2.5mA,
25Vdc or higher.
Input voltage turn on point is programmed with a single resis-
tor from pin 5 to 7. An input turn on/off hysteresis (typically
3.5% of Vin) will be observed. This should be considered when
making or verifying set point adjustment. The value of the
setpoint resistor may be determined by the following:
210·10³
R=
( 10% accuracy at 25ꢀC)
ETO-9.5
Set point temperature coefficient is typically +400ppm/ꢀC.
Output fault monitoring is accomplished by observing pin 5
with a high impedance monitoring circuit. Pin 5 voltage drops
from over 10V to below 1V when a load fault causes the con-
verters fault protection circuitry to activate. It will remain low
for at least 100mS and return high. If the load fault is still
present pin 5 will return low and the cycle will repeat. A resis-
tor >400KΩ from pin 5 to 7 provides pull down for pin 5 if
there is no input setpoint programming resistor already in place.
