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
