Digital Power Factor Correction IC  
Features & Description  
Description  
Digital EMI Noise Shaping  
The CS1500 is a high-performance power factor correction  
(PFC) controller for universal AC input, which uses a proprie-  
tary digital algorithm for discontinuous conduction mode  
(DCM) with variable on-time and variable frequency control,  
ensuring unity power factor, shaping EMI noise, achieving ex-  
cellent efficiency especially at light load conditions.  
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  
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.  
The digital controller optimizes the system stability and tran-  
sient 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.  
• Output Overpower Protection  
• Input Brownout Protection  
• Open/short Loop Protection for IAC & FB Pins  
• Thermal Shutdown
