GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADDC27012DA and ADDC27015DA hybrid military
DC/DC converters with integral EMI filter offer the highest
power density of any DC/DC power converters with their features
and in their power range available today. The converters with
integral EMI filter are a fixed frequency, 1 MHz, square wave
switching DC/DC power supply. They are not variable frequency
resonant converters. In addition to many protection features,
these converters have system level features which allows them to
be used as a component in larger systems as well as a stand-alone
power supply. The units are designed for high reliability and
high performance applications where saving space and/or weight
are critical.
1) 60W/cubic inch power density with an integral EMI filter
designed to meet all applicable requirements in MIL-STD-
461D when installed in a typical system setup.
2) Light weight: 80 grams.
3) Operational and survivable over a wide range of input
conditions: 160-400Vdc; survives low line and high .
4) High reliability; NAVMAT derated.
5) Protection features include:
·
·
·
·
·
output overvoltage protection
output short circuit current protection
thermal monitor/shutdown
input overvoltage shutdown
input transient protection
The ADDC27012DA and ADDC27015DA are available in a
hermetically sealed, molybdenum based hybrid package and are
easily heatsink mountable For MIL-STD-883 devices, contact
factory for availability.
6) System level features include:
·
·
·
·
·
current sharing for parallel operation
inhibit control
output status signal
synchronization for multiple units
input referenced auxiliary voltage
