Description

The device is an off-line converter with an 800 V

avalanche ruggedness power section, a PWM

controller, user defined overcurrent limit,

protection against feedback network

disconnection, hysteretic thermal protection, soft

start up and safe auto restart after any fault

condition. It is able to power itself directly from the

rectified mains, eliminating the need for an

auxiliary bias winding.

Advance frequency jittering reduces EMI filter

cost. Burst mode operation and the devices very

low consumption both help to meet the standard

set by energy saving regulations.
