TR-332

Stress in excess of Absolute Maximum Ratings may
cause permanent damage. Absolute Maximum Ratings,sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceedingthe limits of Output data or Electrical Characteristics.

If exposed to stress above these limits, function and performance may degrade in an unspecified manner.For design margin and to enhance system reliability, it is recommended that the PKJ series DC/DC power modules are operated at case temperatures below 90¡C.

The TR-332 series represents a Òthird generationÓ of High Density DC/DC Power Modules providing 90% efficiency.

To achieve this high efficiency, Ericsson uses proprietary of TR-332 drive and control circuits with planar magnetics and low resistivity multilayer PCB technology, and a patent pending topology with active rectification. The PKJ series can be used without bulky and height consuming heatsinks, resulting in a lower total cost. This TR-332 also provides narrow board spacing for elec-tronic, shelf based applications.

The TR-332 are in the industry standard package size and offer a beneficial alternative to competing products on the market. Because for certain applications they may not  require heatsinks, they are ideal for cost sensitive or high-density applications.

The TR-332 series also offers the flexibility of using a heatsink when needed, enabling reduced airflow, extended reliability or higher ambient temperature operation in a wide range of 48V and 60V DC powered systems. Similar to other Ericsson Power Modules, the TR-332 series includes an under-voltage shut down facility, protecting the associated batter-ies from being too deeply discharged. The TR-332series also offers over-voltage protection, over-temperature protection and is short circuit proof.

These TR-332 are manufactured using highly automated manufacturing lines with a world-class quality commitment and a five-year warranty. Ericsson Components AB has been an ISO 9001 certified supplier since 1991. For product program please see back cover.
