description
constant output current control with no foldback characteristics. HR120
converters are provided with internal filtering elements on both the
input and output to help reduce the need for external components.
The HR120 Series™ of DC/DC converters offers up to 12 watts of
power from single or dual outputs in a single package over a –40°C to
+85°C temperature range. Thick film hybrid manufacturing technology
produces high levels of miniaturization, giving the HR120 Series
converters a low profile (0.330 inch), small board area (1.65 square
inches), and high power density (22 watt/in3).
WiDe Voltage Range
The 5 and 12 volt output models provide full power operation over the
input voltage range of 16 to 40 volts (19 to 40 volts for 15 volt output
models). Operation below 16 volts (or below 19 volts for the 15 volt
output models), including operation in MIL-STD-704E emergency
power conditions, is possible with derated output power. Please refer
to the low voltage drop-out graphs, Figures 9 and 10.
The parts are packaged in sealed steel enclosures, making them ideal
for use in high reliability applications. Each unit is guaranteed to pass
a hermeticity test with a maximum leak rate of 0.001 atm-cc/sec.
Design MethoDology
The HR120 Series provides full power operation at case temperatures
from –40°C up to +85°C. Depending on operating levels, air flow, and
ambient temperature, heat sinking may be required.
The HR120 converters are switching regulators which use a quasi-
square wave, single ended forward converter design with a nominal
switching frequency of 600 kHz. Isolation between input and output
circuits is provided with a transformer in the forward power loop and
a temperature insensitive optical link in the feedback control loop.
Output regulation is accomplished with constant frequency pulse width
modulation. Both line and load regulation are typically within 10 mV.
inhibit FeatuRe
An inhibit terminal is provided that can be used to disable internal
switching, resulting in a very low quiescent input current. An open
collector TTL compatible low (≤0.8 V) is required to control the inhibit
function. This level may be supplied by an open collector gate since
the inhibit pin is provided with an internal pull-up resistor.
On dual output models, the positive output is independently regulated
and the negative output is cross-regulated. Figures 7 and 8 illustrate
what effects load changes have on the negative output.
Indefinite short circuit protection and overload protection are provided
by sensing output load current and restricting the output current to
approximately 125% of full load output current. Since the output
current is sensed in the secondary stage, the result is a predictable,
