Description
General part information
VIPER38 Series
The device is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control. The power MOSFET allows a very high input Vacto be applied, just limited from its breakdown voltage. This IC is capable of meeting more stringent energy-saving standards as it has very low consumption and operates in burst mode under light load.
The device features an adjustable extra power timer (EPT) that enables the IC to sustain overload conditions for a few seconds.
The integrated HV startup, sense FET and oscillator with jitter allow the advantage of using minimal components in the application.
