Datasheet	VIPER38 Datasheet

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 Vac to 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.

VIPER38 VIPerPlus family: peak power high-voltage converter Figure 1.

800 V avalanche-rugged power MOSFET allowing ultra wide range input Vac to be achieved.
Embedded HV start-up and sense FET.
PWM current-mode controller.
OCP with selectable threshold (IDlim) and 2nd OCP with higher value (IDMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode.
30 mW no-load consumption at 230 Vac.
Two operating frequencies:.
60 kHz (L type) or 115 kHz (H type).
Jittered frequency reduces the EMI.
