5.12 X-capacitor discharge time
The power line was unplugged at no-load. The discharge time was measured at the X-
capacitor (470 nF + 470 nF).

5.13 ElectroMagnetic Compatibility (EMC)
The conducted ElectroMagnetic Interference (EMI) of the TEA1916DB1262 prototype
demo board was measured under the following conditions:
•
Load resistor: 0.6 Ω; V
out
= 12.1 V; I
out
=20.1 A
•
V
line
= 230 V/50 Hz or 120 V/50 Hz
The conducted EMI was measured both in the Line and Neutral. The product complies
with the EMC standard.
