High Performance, Breakthrough ISL8200MM Power Module (Intersil)

Intersil launched the latest version of its breakthrough ISL8200M DC/DC power module, the ISL8200MM, designed for harsh applications such as defense and avionics.

The ISL8200MM point-of-load DC/DC power module complies with the specifications of the US Defense Supply Center (DSCC) VID V62/10608. It provides a complete switch-mode power supply in a single package -- military grade temperature electrical performance from -55°C to +125°C and uses tin-lead materials to ensure the highest long-term reliability. All traceability is done by assigning the package and test records by date/tracking code, and Intersil also provides enhanced process change notifications. Combined with parallel load current scalability and extension leads on the QFN package, the ISL8200MM is ideal for defense communications equipment, radar, sonar, defense ground vehicles, and smart regulatory applications.

The ISL8200MM uses Intersil's patented current-sharing architecture to reduce PCB layout noise sensitivity when multiple modules are used in parallel. The device contains almost everything needed for a plug-and-play solution, replacing up to 40 different external components. This high level of integration simplifies and speeds up the design while reducing the power management footprint.

Thermally efficient 23-lead 15 mm x 15 mm QFN package with a large thermal pad on the bottom supports an output power rating of up to 60 watts. Internal high-power components such as power MOSFETs and inductors are soldered directly to the thermal pad to support efficient heat transfer from the module to the PCB. The use of thermally conductive vias on PCBs yields a typical thermal resistance (θ JA) of only 13°C/W. Because most heat transfer is through the PCB, airflow is generally not required.

The module's QFM package has exposed leads around it for pin debugging and solder joint verification. The very small 2.2mm thickness of the ISL8200MM allows it to be mounted on the underside of the PCB with other thin components.
