1. Auto Board Power Testing George Madden Principle Engineer

2. CHALLENGE  Boards are becoming ever complex  Board level power (Point of Loads) solutions are increasing dramatically  Typical complex board have 50+ supplies  Time to market ever decreasing

3. Current Day Solution  Increase power engineer staff to test  Reduce test coverage by eliminating some test cases and do targeted testing of certain supplies  Test only at one range (either minimum input or maximum input)  Push testing to IC vendors

4. Current Day Solution  Using power engineers to perform repetitive testing is not a good use of resource  Reducing test coverage results in reduction of quality, leaves gaps in test coverage and potentially affect yields  Ultimately will cost the company money as problems from manufacturing, field failures and reputation  Push testing to IC vendors will cause delay since most boards use different IC vendors (e.g. LT, Maxim, ADI, Infineon, International Rectifier, MPS, etc), same board will need to be passed between IC vendors to test, further adding additional delay  In addition, IC vendors will in turn bear the burden of test and will need to increase their resources

5. ABT

6. ABT is a high speed fully automated board level power test and report generation tool WHAT IS ABT

7.  Interacts and controls all test equipment  Gathers and stores data in database  Automatically generates report  Testing can be done at a fraction of the time as compared with manual testing ABT Overview

8. TESTs include:  Startup  Shutdown  Switch Node  Load Regulation  Transient  Short Circuit  Loop Response  Efficiency  Above tests done at both min and maximum input voltages TESTS

9.  Quick turn around confidence test results  Test report can be completed in DAYS rather than in weeks  Much money can be saved in terms of test time for the company doing the testing (design team or IC vendor)  Time saved better used to focus on other design challenges BENEFITS TO CUSTOMERS

10.  One Power Supply Demo  From initiation to report generation less than 10 min Video Demo of ABT
