It illustrates all necessary steps to get the board and related environment up and running, and provides all information to become familiar with this comprehensive solution. The ICL5101 is a mixed signal PFC + resonant controller for non-dimmable and dimmable LED light applications using LLC topology for highest efficiency levels exceeding 90 %, including a PFC stage for lowest THD < 5 % and high power factor correction figures > 95 % > 50 % load in a wide line input voltage range. The ICL5101 LLC CC evaluation board is designed to evaluate the performance and flexibility of the ICL5101. It supports an output power of 130 W, easily configurable by using only resistor settings without any user interface tool. Intended audience This document is intended for anyone who needs to use the ICL5101 evaluation board, either for their own application tests or to use it as a reference for a new ICL5101-based development. 1 Revision 1.0, 2016-10-28130 W 76V CC LED Power Supply Demo Board using ICL5101 Table of Contents Table of Contents 1 Order Code / Board Connection / Operation Setup ..........................................................3 1.1 Order Code ..........................................................................................................................................3 1.2 Connection Diagram ...........................................................................................................................3 1.3 Line Input Voltage ...............................................................................................................................3 1.4 Load Output.........................................................................................................................................3 1.5 0 10V Dimming Interface ..................................................................................................................3 2 Introduction ...............................................................................................................4 3 Technical Specification................................................................................................5 4 Schematic ..................................................................................................................6 5 Key Measurements......................................................................................................7 5.1 U I Characteristic, Dimming Performance, PF and THD..................................................................7 5.1.1 U I Characteristic ........................................................................................................................7 5.1.2 Dimming Performance..................................................................................................................8 5.1.3 PF vs. P ......................................................................................................................................9 OUT 5.1.4 THD vs. P .................................................................................................................................10 OUT 5.2 Surge Protection ...............................................................................................................................11 6 Power Magnetic Specification .................................................................................... 12 6.1 Common Mode Choke Spec L1 .........................................................................................................12 6.2 Common Mode Choke Spec L2 .........................................................................................................13 6.3 PFC Choke Spec L6 ............................................................................................................................14 6.4 LLC Resonant Choke Spec L7............................................................................................................15 6.5 LLC Transformer Spec TR1................................................................................................................16 7 Board Layout............................................................................................................ 17 8 Bill of Material (BOM)................................................................................................. 18 Application Note 2 Revision 1.0, 2016-10-28
