ISL6144IRZA - Renesas Electronics

Description: The ISL6144 ORing MOSFET Controller and a suitably sized N-Channel power MOSFET(s) increases power distribution efficiency and availability when replacing a power ORing diode in high current applications. In a multiple supply, fault tolerant, redundant power distribution system, paralleled similar power supplies contribute equally to the load current through various power sharing schemes. Regardless of the scheme, a common design practice is to include discrete ORing power diodes to protect against reverse

ISL6144IRZA Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power and ground connections.
  • Ensure that the output capacitor is properly sized and placed close to the IC. Also, add a small ceramic capacitor (e.g., 10nF) in parallel with the output capacitor to improve stability.
  • The maximum input voltage is 18V, but it's recommended to keep it below 15V to ensure reliable operation and prevent overheating.
  • While it's possible to use a different inductor, it's not recommended. The recommended inductor value and type are optimized for the IC's internal compensation network. Using a different inductor may affect stability and performance.
  • Use the equations provided in the datasheet to calculate the output voltage ripple and noise. Additionally, consider using a post-regulator or additional filtering components to reduce output noise and ripple.
