Description
This stand alone controller provides several special
enhancements to satisfy the needs for low power standby
and protection features. 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.
