Description
The VIPER06 is an offline converter with an
800 V avalanche rugged power section, a PWM
controller, a user-defined overcurrent limit,
open-loop failure protection, hysteretic thermal
protection, soft startup and safe auto-restart after
any fault condition. The device is able to power
itself directly from the rectified mains, eliminating
the need for an auxiliary bias winding. Advanced
frequency jittering reduces EMI filter cost. Burst
mode operation and the device’s very low power
consumption both help to meet the standards set
by energy-saving regulations.
Features
800 V avalanche rugged power section
PWM operation with frequency jittering for
low EMI
Operating frequency:
30 kHz for VIPER06Xx
60 kHz for VIPER06Lx
115 kHz for VIPER06Hx
No need for an auxiliary winding in
low-power applications
Standby power < 30 mW at 265 VAC
Limiting current with adjustable set point
On-board soft-start
Safe auto-restart after a fault condition
Hysteretic thermal shutdown
