Features
Description
The architecture of the EVL6699-90WADP is
based on a two-stage approach; a front-end PFC
pre-regulator based on the L6563H TM PFC
controller and a downstream LLC resonant half
bridge converter using the new L6699 resonant
controller. Thanks to the chipset used, the main
features of this design are very high efficiency,
compliant with ENERGY STAR eligibility criteria
(EPA rev. 2.0 EPS) and very good efficiency at
light load too, compliant with the new ErP Lot 6
Tier 2 requirements. No-load input power
consumption is also very low, well within the
international regulation limits.
The controller of the LLC stage is the L6699,
integrating innovative functions such as self-
adjusting adaptive deadtime, anti-capacitive

mode protection and proprietary “safe-start”
procedure preventing hard switching at startup.
The PFC stage works as pre-regulator and
powers the resonant stage with a constant
voltage of 400 V. The downstream converter
operates only if the PFC is working and regulating
its output voltage. In this way, the resonant stage
can be optimized for a narrow input voltage range
improving the efficiency of the primary side power
components.
The transformer uses the integrated magnetic
approach, incorporating the resonant series
inductance. Therefore, no external, additional coil
is needed for the resonance. The transformer
configuration chosen for the secondary winding is
centre tap.
