This Engineering Evaluation Unit or Demonstration Board must only be used for assessing IC performance in a laboratory setting. This product is not intended for any other use or incorporation into products for sale. This product must only be used by qualified technicians or professionals who are trained in the safety procedures associated with the use of demonstration boards. Risk of Electric Shock • The direct connection to the AC power line and the open and unprotected boards present a serious risk of electric shock and can cause serious injury or death. Extreme caution needs to be exercised while handling this board. • Avoid contact with the exposed conductor or terminals of components on the board. High voltage is present on exposed conductor and it may be present on terminals of any components directly or indirectly connected to the AC line. • Dangerous voltages and/or currents may be internally generated and accessible at various points across the board. • Charged capacitors store high voltage, even after the circuit has been disconnected from the AC line. • Make sure that the power source is off before wiring any connection. Make sure that all connectors are well connected before the power source is on. • Follow all laboratory safety procedures established by your employer and relevant safety regulations and guidelines, such as the ones listed under, OSHA General Industry Regulations - Subpart S and NFPA 70E. Suitable eye protection must be worn when working with or around demonstration boards. Always comply with your employer’s policies regarding the use of personal protective equipment. All components, heat sinks or metallic parts may be extremely hot to touch when electrically active. Heatsinking is required for Q1. The end product should use tar pitch or an equivalent compound for this purpose. For lab evaluation purposes, a fan is recommended to provide adequate cooling.

DS904DB4 CDB1600-120W INTRODUCTION The 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. The CS1600 uses a digital control algorithm that is optimized for high efficiency and near unity power factor over a wide input voltage range 108-305 VAC . The CS1600 uses an adaptive digital control algorithm. Both the ON time and the switching frequency are varied on a cycle-by-cycle basis over the entire AC line to achieve close to unity power factor. The variation in switching frequency also provides a spread frequency spectrum, thus minimizing the conducted EMI filtering requirements. The feedback loop is closed through an integrated digital control system within the IC. Protection features such as overvoltage, overcurrent, overpower, open circuit, overtemperature, and brownout help protect the device during abnormal transient conditions. Details of these features are provided in the CS1600 data sheet. The CDB1600-120W board demonstrates the performance of the CS1600 over a wide input voltage range of 108 to 305 VAC, typically seen in universal input ballast applications. This board has been designed for a 460 V, 115 W full load output application. Extreme caution needs to be exercised while handling this board. This board is to be powered up by trained professionals only. Prior to applying AC power to the CDB1600-120W board, the CS1600 needs to be biased using an external 13 VDC power supply, applied across pins 1 and 2 of terminal block J9. Terminal block J6 is used to connect the AC line. The load is connected to J7. As a safety measure, jumper J1 is provided as a means to apply a small resistive load 200 kΩ minium to rapidly discharge the output capacitors. Other jumpers and test points are provided to evaluate the behavior of the IC and the various sections of the design.
