VIPER37
Description Features This device is an offline converter with an 800 V rugged power section, a PWM control, two levels - 800 V avalanche-rugged power MOSFET allowing ultra wide range input Vac to be achieved of overcurrent protection, overvoltage and overload protection, hysteretic thermal protection, soft-start, and safe auto-restart after the removal of any fault condition. Burst mode operation and - PWM operation with adjustable limiting current very low device consumption help to meet the - 30 m W standby power at 265 Vac - Operating frequency: standby energy saving regulations. Advance frequency jittering reduces EMI filter costs. Brownout function protects the switch mode - 60 k Hz (L type), 115 k Hz (H type) power supply when the rectified input voltage - Frequency jittering for low EMC - Output overvoltage protection level is below the normal minimum level specified for the system. The high voltage startup circuit is embedded in the device. Table 1. Device...
