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 help 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.
