MILITARY DC-DC CONVERTERS
Hi Reliability, Ultra-Miniature, Isolated DC-DC Converters
-55ºC +85ºC Operating Temperature
Wide Input Range, All Units Shielded
Low Profile .300"
No Heat Sink or Electrical Derating Required
This series of high efficiency wide input range, encapsulated regulators come in 42 different models. Manufactured
using high grade military components, this units will operate from -55º C to +85º C with no heat sink or electrical
derating required. The 6 sided shielding and 32 pin DIP compatability combined with input/output isolation and the
wide input range capabilities will meet your most stringent military requirements.

Load regulation (see table for typical variation at
different loads)
Line regulation = Typical values
5-15V DC = ±1.0%
8-24V DC = ±1.0%
18-36V DC = ±2.0%
High efficiency - up to 78%
Will operate over a temperature range of -55º C to
+85º C with no heat sink or electrical derating
6 sided shielding
Isolation - 100 megohms at 500 Volts DC
External output trimming pin standard, +5%
Single and dual isolated outputs
Each unit is supplied with an external control pin. This
"C" pin, when connected to the negative (-) input, will
disable the unit, allowing for remote shutdown.
