DESCRIPTION
The HR150 Series DC/DC converters have been designed to give
industrial applications the same high reliability, small size, and high
performance that Interpoint has provided to military and aerospace
programs since 1969.

ELIABILITY
Each HR150 converter is built to perform reliably in the harshest
environments. Assembled using thick-film hybrid technology, HR150
converters have more uniform thermal coefficients and 50% fewer
connections than converters built by surface mount techniques. The
HR150 converter parts use the same manufacturing procedures and
quality controls that we apply to converters designed for commercial
airliners, the space shuttle, advanced fighter aircraft, and other high
reliability applications. The steel cases are hermetically sealed in a
dry nitrogen environment and are guaranteed a maximum leak rate
of less than 10
atm-cc/sec. All devices are 100% electrically
tested.

ROFILE
The HR150 Series manufacturing techniques provide extremely
small size and low profile components. Each converter uses less
than 2.7 square inches of board area. The overall power density is
from 11 to 17 watts per cubic inch.

ERFORMANCE
The HR150 Series converters are high efficiency, low noise, pulse
width modulated, forward mode switching regulators with a constant
switching frequency of 125 kHz typical for single and dual output
models and 250 kHz typical for triple output models. They achieve
high isolation (500 V, 100 megohm) through use of a transformer in
the forward power circuit and an opto-coupler in the feedback
control loop.
HR 150 Series input ranges are 10 to 16 VDC or 18 to 36 VDC for
single or triple output models and 18 to 36 VDC for dual output
models. Outputs are available as 5, 12, 15, ±12, ±15, +5/±12, and
+5/±15 VDC. The converters typically provide greater than 80% effi-
ciency over the entire input range and from 25% to full load. Line
regulation is typically within 0.1 % and load regulation within 0.2%.
HR150 converters are designed to operate between –40°C and
+85°C case and are short circuit protected up to a case temperature
of 85°C. The combination of high conversion efficiency and heat
dissipating metal enclosures minimizes heat sinking requirements. If
additional dissipation is desired, heat conducting material (PCB,
copper sheet, heat sink, etc.) may be brought into contact with the
unit’s baseplate.
An inhibit function is provided for HR150 converters when the inhibit
input pin is connected to the input common. The open circuit voltage
of the inhibit input pin is 8 to 10 VDC (Vin = 12) or 11 to 13 VDC
(Vin = 28). The inhibit input pin must sink approximately 1 mA
during the inhibit state. During inhibit, the converter’s output voltage
drops to less than 1 volt and the input current is typically 8 mA.
