Description

The STEVAL-ISA142V1 product evaluation board

implements a 50 W, wide-range mains input,

power factor-corrected power supply suitable for

all low power applications requiring a high power

factor, such as lighting applications and LED

power supplies. Use of the low-cost L6564

combined with simple flyback topology provide a

very competitive solution.
