UCR10EVHFSR082 - ROHM Semiconductor

UCR10EVHFSR082 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A recommended PCB layout for optimal thermal performance would be to have a large copper area on the bottom layer connected to the thermal pad, and to use thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended.
• How do I ensure reliable operation at high temperatures?
  To ensure reliable operation at high temperatures, it is recommended to derate the power dissipation according to the temperature derating curve provided in the datasheet. Additionally, ensure that the device is properly mounted and connected to a heat sink or thermal pad to dissipate heat efficiently.
• What is the maximum allowable voltage on the input pins?
  The maximum allowable voltage on the input pins is the absolute maximum rating of 6V, exceeding which may cause damage to the device. It is recommended to keep the input voltage within the recommended operating range of 2.7V to 5.5V.
• How do I handle ESD protection for this device?
  To handle ESD protection for this device, it is recommended to use a human body model (HBM) ESD protection circuit at the input pins, and to follow proper handling and storage procedures to prevent ESD damage.
• What is the recommended capacitor value for the output capacitor?
  The recommended capacitor value for the output capacitor is 10uF to 22uF, with an ESR of less than 100mΩ. The output capacitor should be a low-ESR ceramic capacitor, such as an X5R or X7R type.
