Overview
The CS1601 and CS1601H are digital power factor correction
(PFC) controllers designed to deliver the lowest PFC system
cost in electronic ballast applications. The controller operates
in a variable frequency discontinuous conduction mode (VF-
DCM) with zero-current switching (ZCS) optimized to deliver
best-in-class THD and minimize the size and cost of magnetic
components. The CS1601 operates at switching frequencies
up to 70 kHz while the CS1601H operates at frequencies
extending to 100kHz.
The VF-DCM control algorithm varies both duty cycle and
frequency. This spreads the EMI frequency spectrum, thus
reducing conducted EMI filtering requirements. In addition, the
maximum switching frequency is reached at the peak of the AC
input, which allows for use of a smaller, more cost-effective
boost inductor.
Th e fee dback loop is closed through an integrated
compensation network within the controller, eliminating the
need for additional external components. Protection features
such as overvoltage, overcurrent, open and short-circuit
protection, overtemperature, and brownout protect the system
during abnormal transient conditions.
