Infineon Technologies IR1155 | Demoboard DEMO_200W_12VD
Design of 200 W boost PFC plus HB LLC resonant converter with IR1155, IRS27952 and IR11688
Overview
| Topology | Power Factor Correction |
| Input voltage | 85-265 V |
| Switching frequency | 50-60 kHz |
| Output 1 | 12 V / 16 A |
| IC revision | 2.2 |
Description
The DEMO_200W_12VDC_LLC evaluation board is an off-line isolated power supply designed to provide a 12 V DC output up to amaximum load of 16 A operating from a 50/60 Hz AC-line input voltage between 85 and 265 V AC. The output of this evaluation board is protected against over-load and short-circuit. An over-voltage protection circuit is also included to limit the output voltage. At light loads. This application note gives a detailed description of a 192 W (12 V/16 A) two-stage isolated constant voltage regulated PFC boost plus resonant LLC half-bridge SMPS evaluation board with synchronous rectification based on the IR1155, IRS27952 and IR11688 controllers. Detailed test results and operating waveforms are provided. The board meets an average efficiency of at least 89 percent to meet the European Code of Conduct (EU COC) and US Department of Energy (US DOE) standards for 25 percent, 50 percent, 75 percent and 100 percent loads.
