分享资料个
The device is an off-line converter with an 800 V rugged power section， a PWM control， two levels of over-current 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 help to meet the standby energy saving regulations. Advance frequency jittering reduces EMI filter cost. Brown-out 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.
