Intersil releases new power module for
defense applications
Intersil has unveiled the ISL8200M DC/DC power module designed
for defense, harsh environment and avionics applications.
The ISL8200MM point-of-load DC/DC power module complies
with specifications of the Defense Supply Center (DSCC)
VID V62/10608. It provides a switch-mode power supply in
a single package with full mil-temp electrical performance
from -55°C to +125°C and is built using a tin-lead
finish to assure optimal long-term reliability. Full traceability
is provided through assembly and test by date/trace code
assignment, and Intersil provides enhanced process change
notification. Combined with parallel load current scalability
and extended leads on its QFN package, the ISL8200MM is
ideal for defense communications equipment, radar, sonar,
defense ground vehicles and smart ordinance applications.
The ISL8200MM uses Intersil's patented current share architecture
to reduce PCB layout noise sensitivity when modules are
used in parallel. The device incorporates almost all of
the components required to deliver a plug-and-play solution,
replacing as many as 40 different components. This high
level of integration simplifies and speeds designs while
reducing the power management footprint.
A thermally efficient 23-lead, 15mm x 15mm QFN package
with large conductive pads on the bottom enables output
power levels up to 60W. Internal high power components such
as power MOSFETs and inductors are soldered directly to
the conductive pads, enabling efficient heat transfer from
the module to the PCB. Using thermal vias on the PCB results
in a typical thermal resistance (theta JA) of only 13°C/W.
Because most heat transfer is through the PCB, airflow is
generally not required.
The module's QFN package has exposed leads around its perimeter,
which allows access to pins for debug and solder joint verification.
The ISL8200MM has a 2.2mm profile that enables it to be
mounted to the bottom side of the PCB with other low-profile
components.
