RQ6E035ATTCR - ROHM Semiconductor

RQ6E035ATTCR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
• How do I ensure the stability of the output voltage?
  To ensure stability, a minimum output capacitance of 10uF with an ESR of 1Ω or less is recommended. Additionally, a 1uF ceramic capacitor should be placed close to the VIN pin to filter out high-frequency noise.
• What is the maximum input voltage that can be applied to the VIN pin?
  Although the datasheet specifies a maximum input voltage of 6.5V, it's recommended to limit the input voltage to 6.2V or less to ensure reliable operation and prevent damage to the device.
• How do I protect the device from overcurrent conditions?
  A fuse or a current-limiting resistor can be added in series with the input voltage to prevent overcurrent conditions. Additionally, the device has a built-in overcurrent protection (OCP) feature that will limit the output current to 2.5A.
• What is the recommended input capacitor type and value?
  A low-ESR ceramic capacitor with a value of 4.7uF to 10uF is recommended for the input capacitor. This helps to filter out high-frequency noise and ensure stable operation.
