Description

The STEVAL-ILL055V1 is an isolated SMPS

designed in high power factor flyback topology. It

generates a 640 mA nominal output current,

delivering up to 11 W of output power and

provides a cost-effective and space-saving

solution. This product evaluation board is based

on the HVLED815PF, a monolithic converter

integrating both an 800 V avalanche-rugged

MOSFET and PWM controller in a single

package.
