ISL6742AAZA - Renesas Electronics

Description: The ISL6742 is a high-performance double-ended PWM controller with advanced synchronous rectifier control and current limit features. It is suitable for both current- and voltage-mode control methods. The ISL6742 includes complemented PWM outputs for Synchronous Rectifier (SR) control. The complemented outputs may be dynamically advanced or delayed relative to the main outputs using an external control voltage. Its advanced current sensing circuitry employs sample and hold methods to provide a precise avera

ISL6742AAZA 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 high-current paths.
  • Ensure that the output capacitor has a low ESR and is properly sized for the output current. Also, add a small ceramic capacitor (e.g., 10nF) in parallel with the output capacitor to improve stability.
  • The input voltage ripple should be kept below 1% of the nominal input voltage to ensure reliable operation. Excessive ripple can cause the regulator to malfunction or oscillate.
  • While it's possible to use a different inductor value or type, it's not recommended. The recommended inductor value and type are optimized for the regulator's performance and stability. Using a different inductor may affect the regulator's performance, efficiency, or stability.
  • Implement overcurrent protection using a fuse or a current-sensing resistor. Also, ensure good thermal design and heat sinking to prevent overheating. Monitor the junction temperature and shut down the regulator if it exceeds the maximum allowed temperature.
