ISL9241HRTZ-T7A - Renesas Electronics

Description: The ISL9241 is a digitally configurable buck-boost battery charger that can support both Narrow Voltage Direct Charging (NVDC) and Hybrid Power Buck-Boost (HPBB/Bypass) charging and switch between the modes using firmware control. Bypass mode is also supported using the firmware of the controller, which allows the adapter to provide power directly to the system. The ISL9241 provides charging functionality, system bus regulation, and protection features using only NFETs for tablet, Ultrabook, and notebook pl

ISL9241HRTZ-T7A Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
  • Ensure proper thermal design, use a low-ESR output capacitor, and follow the recommended PCB layout guidelines. Also, consider using a thermistor or thermocouple to monitor the temperature.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this may affect the converter's stability and reliability.
  • While possible, it's not recommended. The recommended inductor value and type are optimized for the converter's performance and efficiency. Using a different inductor may affect the converter's stability and efficiency.
  • Check the input voltage, output load, and feedback resistors. Verify that the feedback pin is properly connected and that the output voltage is within the specified range. Consult the datasheet and application notes for troubleshooting guidelines.
