IMPORTANT SAFETY INSTRUCTIONS

Read and follow all safety instructions prior to using this demonstration board.

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 and metallic parts may be extremely hot to touch when electrically active.

INTRODUCTION

The CS1610A is a 120VAC quasi-resonant flyback mode dimmable LED controller IC. The CS1610A uses a digital control algorithm that is optimized for high efficiency and power factor over a wide input voltage range 108VAC to 132VAC . The CS1610A integrates a critical conduction mode CRM boost converter that provides power factor correction and dimmer compatibility with a constant output current, quasi-resonant flyback stage. An adaptive dimmer compatibility algorithm controls the boost stage and dimmer compatibility operation mode to enable flicker-free operation to <2% output current with leading-edge, trailing-edge, and digital dimmers.

The CDB1610A-8W board is optimized to deliver low system cost in a high-efficiency, flicker-free, phase-dimmable, solid-state lighting SSL solution for incandescent lamp replacement applications. The feedback loop is closed through an integrated digital control system within the IC. The variation in switching frequency also provides a spread-frequency spectrum, thus minimizing the conducted EMI filtering requirements. Protection algorithms such as output open/short, current-sense resistor open/short, and overtemperature thermistors protect the system during abnormal conditions. Details of these features are provided in the CS1610A/11A/12A/13A TRIAC Dimmable LED Driver IC data sheet.

The CDB1610A-8W board demonstrates the performance of the CS1610A. This reference board has been de-
signed for an output load of in series at 460mA 14.6V typical .

This document provides the schematic for the board. It includes oscilloscope screen shots that indicate various operating waveforms. Graphs are also provided that document the performance of the board in terms of Efficiency vs. Load and Power Factor vs. Load for the CS1610A dimmable LED controller IC.

Extreme caution needs to be exercised while handling this board. This board is to be used by trained professionals only.
