ST VIPER27LN

隔离8.5V ~ 23.5V20 W

Overview

The VIPER27LN is an offline High Voltage Converter with an 800V 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. 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.
