4 Circuit Performance for Surge Tests
Figure 4-1 to Figure 4-4 shows the performance of the TPS2660 for positive and negative 500-V, 2-Ω, 8/20-µs surge pulses. The output voltage waveform shows that the device shuts-down and re-starts without operator intervention after all of the surge related oscillations are over and provides criteria B performance. For circuits to give criteria A performance, contact the application engineer on the E2E Forum.
