overview:
The CS1501/1601 are high-performance Variable
Frequency Discontinuous Mode, active digital power
factor correction (PFC) controllers. They feature Cirrus
Logic’s EXL Core
digital energy control which elevates performance
and reduces total solution size.
The unique digital architecture of our PFC controllers
enables a reduction in the boost inductor value (L
the size of the EMI filter stage and many external
passive components.
FeatureS:
Mains
AC
Superior light-load efficiency, top-end power factor
correction, unsurpassed THD
Smaller boost inductance needed versus critical
conduction mode (CRM)
Digital EXL Core enables intelligent and adaptive
switching
Pin-out similar to top analog CRM solutions
Current sense and zero crossing detect (ZCD)

Variable on-time/ variable frequency algorithm is
used in achieving close to unity power factor and
spreading the EMI frequency spectrum, thus reducing
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 protection, over
temperature, and brownout) help protect the device
during abnormal transient conditions.
