VIPER27LDTR Converter Offline Flyback Topology 60kHz 16-SO 800V 20
WDescriptionThe 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.
