recorders, white goods

Description

The device is an off-line converter with an 800 V

rugged power section, a PWM control, double

levels of overcurrent protection, overvoltage 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. The quasi-

resonant feature reduces EMI filter cost. Brown-

out and brown-in function protects the switch

mode power supply when the rectified input

voltage level is below the normal minimum level

specified for the system. The high voltage start-up

circuit is embedded in the device.
