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 evaluation board passes EMI conductive, radiated and is CE certificated. 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 94 %, 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 evaluation board is designed to evaluate the performance and flexibility of the ICL5101. It supports an output power of 110 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 2.2, 2015-09-22 110 W / 54 V Power Supply Demo Board using ICL5101 Table of Contents Table of Contents 1 Introduction ............................................................................................................... 3 2 Technical Specification ................................................................................................ 4 3 Schematic .................................................................................................................. 5 4 Key Measurements and Waveforms ............................................................................... 6 4.1 Line Regulation, Startup Time, Load Regulation, PF and THD .......................................................... 6 4.1.1 Line Regulation ............................................................................................................................. 6 4.1.2 Startup Time .................................................................................................................................. 7 4.1.3 Load Regulation ............................................................................................................................ 9 4.1.4 PF and THD vs. P ....................................................................................................................... 9 OUT 4.2 Surge Protection ............................................................................................................................... 12 4.3 Harmonics ......................................................................................................................................... 13 4.4 System Efficiency and Standby Power ............................................................................................. 14 4.4.1 System Efficiency ........................................................................................................................ 14 4.4.2 Power Consumption at Output Open Loop (Standby Power) ................................................... 15 4.5 EMI Test .............................................................................................................................................. 16 5 Surge, Flicker & Burst Test Results .............................................................................. 20 5.1 Surge .................................................................................................................................................. 20 5.2 Flicker ................................................................................................................................................ 21 5.3 Burst ................................................................................................................................................... 23 6 Power Transformer Specification ............................................................................... 24 6.1 Common Mode Choke Spec L1 ......................................................................................................... 24 6.2 PFC Choke Spec T1 ............................................................................................................................ 25 6.3 LLC Resonant Choke Spec L2 ............................................................................................................ 26 6.4 LLC Transformer Spec T2 .................................................................................................................. 27 7 Board Layout ............................................................................................................ 28 8 Bill of Material (BOM)................................................................................................. 29 9 References ............................................................................................................... 33 Application Note 2 Revision 2.2, 2015-09-22
