VIPER06XN

The VIPER06 is an offline converter with an 800 V avalanche rugged power section, a PWM controller, a user-defined overcurrent limit, open-loop failure protection, hysteretic thermal protection, soft startup and safe auto-restart after any fault condition. The device is able to power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. Advanced frequency jittering reduces EMI filter cost. Burst mode operation and the device’s very low power consumption both help to meet the standards set by energy-saving regulations.5 V/0.8 W wide-range 30 kHz buck converter based...Auxiliary power supply in buck-boost topology ba...3W, 5V output, isolated flyback converter using ...Wide range single-output demonstration board bas...12 V, 150 mA non-isolated buck converter using V...4 W, 12 V output, isolated flyback converter usi...
