CS1600 Datasheet Low-cost Pfc Controller

Manufacturer: Cirrus Logic

Overview: CS1600 www.DataSheet4U.com Low-cost PFC Controller for Electronic.

General Description

 Lowest PFC System Cost for Electronic Ballasts  Variable Frequency Discontinuous Conduction Mode  Improved Efficiency Due to Variable Switching Frequency  EMI Signature Reduction from Digital Noise Shaping  Integrated Feedback Compensation  Overvoltage Protection with Hysteresis  Overpower Protection with Shutdown  UVLO with Wide Hysteresis  Thermal Shutdown with Hysteresis Description CS1600 is a high-performance Variable Frequency Discontinuous 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.
