Ripple and noise measurement method: using a 12 "twisted pair, while the terminal to be parallel 0.1uf and 47uf capacitor measured at 20MHz of bandwidth.
Accuracy: includes set up tolerance, line regulation and load regulation.
Linear adjustment rate measuring method: rated load from low voltage to the high voltage test.
Load regulation measurement methods: from the rated load of 0% to 100%.
Over temperature protection is decided by the control functionality of the IC (U1), IC sensitivity specifications provided by the supplier.
