Copyright Cirrus Logic, Inc. 2010 (All Rights Reserved) Cirrus Logic, Inc. http://www.cirrus.com CS1500 Digital Power Factor Correction IC Features & Description Digital EMI Noise Shaping Excellent Efficiency Under All Load Conditions Minimal External Devices Required Optimized Digital Loop Compensation Comprehensive Safety Features • Undervoltage Lockout (UVLO) • Output Overvoltage Protection • Input Current Limiting • Output Overpower Protection • Input Brownout Protection • Open/short Loop Protection for IAC & FB Pins • Thermal Shutdown Description The CS1500 is a high-performance power factor correction (PFC) controller for universal AC input, which uses a proprietary digital algorithm for discontinuous conduction mode (DCM) with variable on-time and variable frequency control, ensuring unity power factor. The CS1500 incorporates all the safety features necessary for robust and compact PFC stages. In addition, it has burst mode control to lower the light-load/standby losses to a minimum. Protection features such as overvoltage, overcurrent, overpower, open- and short-circuit protection, overtemperature, and brownout help protect the device during abnormal transient conditions. The digital controller optimizes the system stability and transient performance, simplifies the PFC design, reduces the external component count and BOM costs. The simple design and minimum cost makes CS1500 the ideal choice for PFC up to 300 watts.
