Bringing Up a Flyback Supply for the First Time
This course describes the complete procedure for properly bringing up your flyback supply for the first time. This test procedure will help you safely start-up your power supply without damaging components (or yourself), and will help you thoroughly evaluate your new design for basic functionality. Several often-overlooked performance tests will reveal hidden defects in your design that can lead to problems during later testing. Take this course to learn the correct way to bring up and test your power supply.

we make SMPS ckt using TNY280 As constant Voltage 12V/2A
But we found some following problem
1)some of SMPS generate audioable noise.
2)some SMPS trip by giving 2A load.
reply me about above problem
