Description
General part information
EVL400W-80PL Series
The EVL400W-80PL demonstration board is a 12 V - 400 W converter, tailored to the typical specifications of an AC/DC adapter with wide input mains range, very low power consumption at light load and good average efficiency.
It is composed by a motherboard mounting the high voltage power devices, the primary control board mounting the IC controllers L4985A and L6699 and the secondary control board for the synchronous rectification.
The architecture is based on a two-stage approach: a front-end PFC pre-regulator based on a CCM (Continuous Conduction Mode) boost PFC controller using the L4985A, and a downstream LLC resonant half-bridge converter, designed around the L6699.
