Description
CS1600 is a high-performance Variable Frequency Discontinu-
ous Conduction Mode (VF - DCM), active Power Factor
Correction (PFC) controller, optimized to deliver the lowest PFC
system cost for electronic ballast applications.
A variable ON time / variable frequency algorithm is used to
achieve near unity power factor. This algorithm spreads the EMI
frequency spectrum, which reduces the conducted EMI filtering
requirements. The feedback loop is closed through an integrated
compensation network within the IC, eliminating the need for
additional external components. Protection features such as
overvoltage, overcurrent, overpower, open- and short-circuit pro-
tection, overtemperature, and brownout help protect the device
during abnormal transient conditions.
