The CRD1500-90WLLC circuit has two stages: a
digitally controlled front-end PFC and a resonant LLC
converter. The CS1500 is a high-performance power
factor correction (PFC) controller for universal AC input
that uses a proprietary digital algorithm with variable on-
time, variable frequency, & DCM, which ensures unity
power factor.
The resonant LLC converter uses the L6599A controller
in the second stage.
