DESCRIPTION
With a miniature footprint of just 0.8 square inches, the HSH
Series of DC/DC converters delivers 1.5 watts of output power
while saving significant board real estate. The wide input voltage
range of 6 to 20 VDC accepts the varying voltages of military, indus-
trial, or battery 15V bus power and tightly regulates output voltages
to protect downstream components. Transient protection of 40 volts
for up to 120 milliseconds.

ESIGN
HSH Series DC/DC converters incorporate a flyback topology with a
variable frequency, nominally 370 kHz. Output voltage is magneti-
cally fed back to the input side of the PWM to regulate output volt-
age.
Up to 80% of the load may be on one output providing that the other
output carries a minimum of 20% of the total load. This dual model
can be used as a single output voltage by connecting the load
between positive and negative outputs, leaving the common uncon-
nected resulting in double the output voltage. (ex: HSH1205D can
be used as a 10 VDC output.)

UNCTION
When an open collector TTL logic low is applied to the inhibit termi-
nal, pin 7, the converter shuts down and lowers the output voltage
to near zero and input current to as low 5 mA. Leaving the terminal
open or applying an open collector TTL logic high will enable the
converter.
MIL-STD-461
Use Interpoint’s FMSA-461 EMI filter to pass the CE03 requirements
of MIL-STD-461C.

ACKAGING
The HSH Series converters are packaged in hermetically sealed
metal cases which provide EMI/RFI shielding and protection from
the environment.
