Description
The device is an off-line converter with an 800 V
rugged power section, a PWM control, two levels
of over-current protection, over-voltage and
overload protections, hysteretic thermal
protection, soft-start and safe auto-restart after
any fault condition removal. Burst mode operation
and device very low consumption helps to meet
the standby energy saving regulations. Advance
frequency jittering reduces EMI filter cost. The
extra power timer allows the management of
output peak power for a designed time window.
The high voltage start-up circuit is embedded in
the device.
