Abstract

New DC-DC converters such as Voltage Regulator Modules (VRMs) and Point of Load (POL) cards are being designed to automatically configure into different output configurations depending upon the application in which they are inserted. This idea focuses upon new test methods which need to be developed to allow verification of functionality of multiple configurations on a single test vehicle using a Multi-Output-Configurable Test Fixture (MOC-TF).

Muti-phase Multi-Ouput Configurable Test Card / Fixture.

New DC-DC converters such as Voltage Regulator Modules (VRMs) and Point of Load (POL) cards are being designed to automatically configure into different output configurations depending upon the application in which they are inserted. Because of this, test methods need to be developed to allow verification of functionality of multiple configurations on a single test vehicle under one Multi-Output-Configurable Test Fixture (MOC-TF).

In today's test environment, a manufacturer's functional tester can only support testing a single configuration of a DC-DC converter at a time.

The novel concept of a Multi-Output-Configurable Test Fixture (MOC-TF) is introduced. The novelty of this concept is a new type of configurable test fixture which will enable testing for varying configurations of multi-output power devices or assemblies. The novel approach of the MOC-TF consists of a flexible test fixture which can support multi -phase, multi-output test configurations on DC power converters. Each device or assembly can be connected to any parallel dc-dc converter via a low impedance short desirable to a specific value. This allows the testing of multiple converter/assembly configurations on a single fixture. Test fixtures are set up so that devices or assemblies are routed to specific output paths. This fixture modification using low impedance devices that can be switched to various configurations will allow converters /assemblies to operate in any valid configuration of the devices. This will eliminate the need for multiple test fixtures to test all valid configurations.

For the MOC-TF to operate, the desired implementation will take the following into consideration. The MOC-TF configuration will be able to allow the phases to be configured to match the desig...
