VIPER38LD Description

The VIPER38LD is a high-voltage converter that smartly integrates an 800 V rugged power MOSFET with PWM current-mode control. The power MOSFET VIPER38LD allows a very high input Vac to be applied, just limited by 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 VIPER38LD features an adjustable extra power timer (EPT) that enables the IC to sustain overload conditions for a few seconds.

VIPER38LD Features

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 a selectable threshold (IDlim) and 2nd

OCP with a 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

Extra power timer (EPT) blanks the overload current for a few seconds

VIPER38LD Applications

Auxiliary power supply for consumer and home equipment

Power supply for energy meters and data concentrators

Adapters

Automotive

Hybrid, electric & powertrain systems

Industrial

Aerospace & Defense

Enterprise systems

Enterprise machine
