• Manufacturer Part Number: ISL6144
• Description: High Voltage ORing MOSFET Controller
• Manufacturer: Intersil Corporation

General Application Circuit
NOTES:
5. AC/DC 1 through (N + 1) are multistage AC/DC converters which include AC/DC rectification stage and a DC/DC Converter with a +48VDC
6. DC/DC Converter 1 through (N + 1) are DC/DC converters to provide additional Intermediate Bus
7. Load “+12V” and Load “+48V” might include other DC/DC converter stages to provide lower voltages such as ±15V, ±5V, +3.3V, +2.5V,
8. Fuse location might vary depending on power system architecture.
