In standby mode frequency reduction is used to lower the power consumption and provide a stable output voltage in this mode. The frequency reduction is limited to 20kHz / 21.5 kHz (typ.) to avoid audible noise. In case of failure modes like open loop, overvoltage or overload due to short circuit the device switches in Auto Restart Mode which is controlled by the internal protection unit. By means of the internal precise peak current limitation the dimension of the transformer and the secondary diode can be lower which leads to more cost efficiency. |
