CS1500 90W, High-efficiency PFC
w/ LLC Resonant Converter Reference Design
General Description
 Universal Input
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 ontime, variable frequency, & DCM, which ensures unity
power factor.
– Mains Range: 90~265 VAC
– Line Frequency: 45~65 Hz
 Rated Output Specification: 19 V, 90 W
 EN6100-3-2 Class-D Compliance
 Efficiency: 91% @ 90 W, 230 VAC
 Low No-load Power Dissipation
 Low PFC Component Count
 Board Dimension: 61 mm x 135 mm
The resonant LLC converter uses the L6599A controller
in the second stage.
