ISL9241HRTZ-TK - 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-TK 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 and ensure good thermal conductivity to the surrounding components.
  • Use a low-ESR output capacitor (e.g., ceramic or polymer) and ensure the capacitor is placed close to the output pins. Additionally, use a low-inductance layout and minimize the loop area to reduce the ripple.
  • The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • Ensure the input voltage is stable and within the recommended range before enabling the device. Also, add a soft-start capacitor (e.g., 10nF) to the EN pin to prevent inrush currents.
  • Use a low-ESR capacitor (e.g., ceramic or polymer) with a value between 10uF to 22uF. The capacitor should be placed close to the VIN pin and have a voltage rating of at least 30V.
