The second genera
tion CoolSET?-F2 provides several special enhancements to satisfy the needs f
or low power standby and pro
tection features。 In standby mode frequency reduction is used to lower the power consumption and support a stable output voltage in this mode。The frequency reduction is limited to 20kHz/21.5 kHz to avoid audible noise。 In case of failure modes like open loop, overvoltage or overlo
ad due to short circuit the device switches in Auto Restart Mode which is control
led 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 sized lower which leads to more cost effective for the overall system。
