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.
Contacting Cirrus Logic Support

CRD1615A-8W
1. INTRODUCTION
The CS1615A is a 120VAC quasi-resonant flyback mode dimmable LED controller IC. The CS1615A uses a digital
control algorithm that is optimized for high efficiency and > 0.99 power factor over an input voltage range (108VAC
to 132VAC). The CS1615A integrates a dimmer compatibility circuit with a constant output current, quasi-resonant
flyback stage. An adaptive dimmer compatibility algorithm controls the dimmer compatibility operation mode to enable flicker-free operation from 0% to 100% output current with leading-edge, trailing-edge, and digital dimmers.
The CRD1615A-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. Protection algorithms such as output open/short,
current-sense resistor open/short, and overtemperature thermistors protect the system during abnormal conditions.
When using the CS1615A for a design that does not require active clamp circuitry, the CLAMP pin should be left
floating. Details of these features are provided in the CS1615A/16A data sheet DS1033 Single Stage Dimmable
Controller for LED Lamps.
The CRD1615A-8W board demonstrates the performance of the CS1615A. This reference board has been designed for an output load of 10  LEDs in series at 250mA (  30.0V typical).
This data sheet provides the schematic and PCB layout for the reference design board. The performance graphs
demonstrate the performance of the CS1615A dimmable-controller reference design in terms of Efficiency vs. Line
Voltage, Power Factor vs. Line Voltage, THD vs. Line Voltage, Output Current vs. Line Voltage, and Output Current
vs. Dim Angle.
Extreme caution needs to be exercised while handling this board. This board is to be used by trained professionals
only.

CRD1615A-8W
7. TRANSFORMER CONSTRUCTION
The CRD1615A-8W provides power factor correction and dimmer compatibility with a constant output current, quasiresonant flyback stage. The following sections describe the flyback transformer installed on the CRD1615A-8W.
7.1
Flyback Transformer
The flyback transformer stage is a quasi-resonant peak current-regulated DC-DC converter capable of delivering
the highest possible efficiency with constant current output while minimizing line frequency ripple. The auxiliary winding is used for zero-current detection and overvoltage protection.
