RSQ035P03HZGTR - ROHM Semiconductor

RSQ035P03HZGTR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  ROHM recommends a PCB layout with a thermal pad connected to a large copper area to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal via array under the IC can help to reduce thermal resistance.
• How do I ensure the device is properly biased for optimal performance?
  The RSQ035P03HZGTR requires a stable input voltage (VIN) between 2.5V to 5.5V. Ensure the input voltage is well-regulated and decoupled with a 10uF ceramic capacitor. Also, the EN pin should be pulled high to enable the device.
• What is the maximum allowable power dissipation for this device?
  The maximum power dissipation (PD) for the RSQ035P03HZGTR is 1.5W. However, this value can be derated based on the ambient temperature and PCB layout. ROHM recommends following the thermal derating curve in the datasheet to ensure safe operation.
• Can I use this device in a high-temperature environment?
  The RSQ035P03HZGTR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at higher temperatures. ROHM recommends following the recommended operating conditions and derating the power dissipation accordingly.
• What is the recommended ESD protection for this device?
  ROHM recommends using a TVS diode or a transient voltage suppressor to protect the RSQ035P03HZGTR from electrostatic discharge (ESD). The TVS diode should be connected between the VIN pin and the GND pin.
