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 8 to 20 VDC accepts the varying voltages of military,
industrial, or battery 12 V bus power and tightly regulates output
voltages to protect downstream components.
Converter Design
HSH Series DC/DC converters incorporate a flyback topology
with a ­variable frequency, nominally 370 kHz. Output voltage is
magnetically fed back to the input side of the PWM to regulate
output voltage.
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 unconnected resulting in double the output voltage. (ex:
HSH1205D can be used as a 10 VDC output.)
Inhibit Function
When an active low is applied to the inhibit terminal, 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 active high will enable the converter.
MIL-STD-461
Use Interpoint’s FMSA-461 EMI filter to pass the CE03 require-
ments of MIL-STD-461C.
Convenient Packaging
The HSH Series converters are packaged in hermetically sealed
metal cases which provide EMI/RFI shielding and protection from
the environment.
