The IRAC1150-300W Demo Board is a demo board featuring the IR1150S Power Factor Correction control IC. The document describes the features and characteristics of the demo board.
The IRAC1150-300W Demo Board demonstrates the performance of the IR1150S Power Factor Correction control IC in a 300 W continuous‑conduction‑mode boost converter. The board accepts universal AC input (85‑264 VAC) and delivers a regulated 387 VDC output.
The guide includes detailed specifications, schematic diagrams, PCB layout, bill of material, step‑by‑step operating procedures, performance data such as power factor and EMI, and extensive safety warnings for handling the high‑voltage circuitry.
| AC Line Voltage Range | 90–264 VAC |
|---|---|
| Output Voltage | 387 VDC ±2.5% |
| Maximum Output Power | 300 W |
| Efficiency @ 90 VAC / 300 W | 92 % |
| Power Factor @ 115 VAC / 300 W | 0.999 |
| Operating Ambient Temperature Range | 0 °C – 40 °C |
| Converter Switching Frequency | 100 kHz ±11% |
The recommended voltage is 14 V, and a maximum of 22 V can be applied without damaging the IC.
Use an isolation transformer on the AC side, avoid personal contact with the board while AC voltage is present, wear safety glasses, and monitor input and output voltages.
The board provides a regulated 387 VDC output with a tolerance of ±2.5 %.
The demo board is designed for continuous operation at a load of up to 300 W.
