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, 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.
Contacting Cirrus Logic Support

1. INTRODUCTION
The CS1501 is a high-performance Variable Frequency Discontinuous Conduction Mode (VF-DCM), active Power Factor Correction (PFC) controller, optimized to deliver the lowest system cost in switched
mode power supply (SMPS) applications. The CS1501 uses a digital control algorithm that is optimized
for high efficiency and near-unity power factor over a wide input voltage range (90-265 VAC).
Using 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 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. Burst mode control minimizes the light-load/standby losses. 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
CS1501 data sheets.
The CDB150x-01 board demonstrates the performance of the CS1501 with input voltage range of 90-265
VAC, typically seen in universal input applications. This board has been designed for 400V Vlink, 90
Watts, full load.
Extreme caution needs to be exercised while handling this board. This board is to be used by trained professionals only. Prior to applying AC power to the CDB150x-01 board, the CS1501 needs to be biased
using an external 13 VDC power supply.
This document provides the schematic for the board. It includes oscilloscope screen shots that indicate
operating waveforms. Graphs are also provided that document the performance of the board in terms of
Efficiency vs. Load, Total Harmonic Distortion vs. Load, and Power Factor vs. Load for the CS1501 PFC
controller IC.
