Product overview
Description
VIPER35 is a high voltage converter, which smartly integrates an 800 V rugged power MOSFET with a quasi-resonant current mode PWM control. This IC meets severe energy saving standards as it has very low consumption and operates in burst mode under light load conditions.
The VIPER35 features the brown-out enabling the IC to set the switch-off and switch-on threshold independently one of each other. The quasiresonant operation reduces the level of EMI and the quantity of components in the application.
The quasi-resonant operation reduces the switching losses and improves power conversion efficiency. The device features high level protections such as: output overvoltage, shortcircuit and thermal shutdown with hysteresis.
After the removal of a fault condition, the IC is automatically restarted.
