Infineon Technologies ICL5101 | Demoboard Application Note
110 W / 54 V Power Supply Demo Board using ICL5101
Overview
| Topology | LLC Resonant Converter |
| Input voltage | 85-305 V |
| Switching frequency | 45-135 kHz |
| Output 1 | 54 V / 2.06 A |
| IC revision | 2.2 |
Description
This application note describes the characteristics and features of a 110 W SMPS demonstration board withconstant 54 V voltage output. High efficiency, high PF, low THD and very stable output voltage with lowripple at whole power range are the key features of this demonstration board, which makes it very suitableto be used as a primary power supply for low power systems, such as LED lighting. Its compact design andlow BOM cost is due to Infineon IC ICL5101 (CrCM PFC and resonant block are integrated together), which isused as main controller here. With this highly integrated smart IC, the circuit design is dramaticallysimplified, which results space and BOM cost saving. Furthermore, numerous monitor and protectionfeatures ensure highest reliability.
