General Description

The CRD1500-FB circuit has two stages: a digitally

controlled front-end PFC and a quasi-resonant flyback

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 quasi-resonant flyback converter uses the L6566A

flyback controller and is dedicated to controlling the

circuit’s standby/normal operation mode, which controls

the on/off state of the PFC stage by means of a

dedicated pin (Vcc_PFC), which helps to achieve an

excellent efficiency at light-load and no-load conditions.
