8A34045E-000NLG Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN4393EJ0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
  • Renesas recommends following the thermal design guidelines, using a heat sink if necessary, and ensuring proper airflow around the device. Additionally, the device's thermal protection feature can be enabled to prevent overheating.
  • Renesas recommends using a low-ESR capacitor (e.g., ceramic or film capacitor) for CIN, with a value between 1-10uF. For COUT, a capacitor with a value between 10-100uF is recommended, depending on the output voltage and load requirements.
  • Renesas recommends using a higher value for the input capacitor (CIN) and ensuring that the input voltage is above the minimum specified voltage (VIN_MIN) to maintain stable operation. Additionally, the device's UVLO (Under-Voltage Lockout) feature can be adjusted to optimize performance at low input voltages.
  • Renesas recommends using a ceramic capacitor with a value between 10-100nF for CBST, and a fast-recovery diode (e.g., Schottky diode) for DBST, with a voltage rating that exceeds the maximum output voltage.
