ISL81802FRTZ-T7A - Renesas Electronics

Description: The ISL81802 is a dual synchronous buck controller that generates two independent outputs or one output with two interleaved phases for a wide variety of applications in industrial and general purpose segments. With a wide input and output voltage ranges, the controller is suitable for telecommunication, data center, and computing applications.The ISL81802 uses peak current mode control with phase interleaving for the two outputs. Each output has a voltage regulator, current monitor, and average current reg

ISL81802FRTZ-T7A Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
  • Use a twisted pair cable, keep the cable length under 4000 feet, and terminate the bus with a 120-ohm resistor at each end. Also, ensure that the transmitter and receiver are properly configured and synchronized.
  • The maximum cable length is dependent on the baud rate and the specific application. As a general guideline, the maximum cable length is 4000 feet at 9600 bps and 1000 feet at 115200 bps.
  • Use a common-mode choke or a TVS diode to protect the transceiver from voltage transients. Also, ensure that the system is properly grounded and that the cable is properly shielded.
  • Power up the VCC pin first, followed by the VDD pin. Ensure that the VCC pin is stable before applying a signal to the VDD pin.
