PTZTFTE252.4B Frequently Asked Questions (FAQs)

  • ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • ROHM recommends derating the power dissipation according to the temperature derating curve in the datasheet. Additionally, ensure good airflow and thermal management around the device.
  • The maximum allowable voltage for the input pins is the supply voltage (VCC) + 0.3V. Exceeding this voltage may cause damage to the device.
  • Yes, the PTZTFTE252.4B is suitable for switching regulator applications. However, ensure that the device is properly bypassed and decoupled to minimize noise and voltage spikes.
  • Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Refer to the datasheet for the maximum allowable power dissipation and thermal resistance values.
