BU33TA2WHFV-TR Frequently Asked Questions (FAQs)

  • ROHM recommends a thermal pad size of at least 2mm x 2mm with multiple vias to the ground plane to ensure efficient heat dissipation. A thermal resistance of 10°C/W or less is achievable with proper layout design.
  • To ensure stable operation, ROHM recommends a soft-start circuit or a ramp-up/ramp-down power supply to prevent inrush currents and voltage overshoots. Additionally, a 10uF or larger capacitor on the input pin can help filter out noise and voltage transients.
  • Although the datasheet doesn't specify a maximum voltage for the enable pin, ROHM recommends keeping it within the range of 0V to VCC (3.3V) to ensure proper operation and prevent damage to the device.
  • While the BU33TA2WHFV-TR is rated for operation up to 125°C, ROHM recommends derating the output current and power dissipation to ensure reliable operation in high-temperature environments. Consult ROHM's application notes for specific guidance.
  • ROHM recommends checking the input voltage, output current, and thermal conditions to identify the root cause of the issue. Additionally, verify that the PCB layout and component selection meet the recommended specifications. If issues persist, consult ROHM's technical support or application notes for further guidance.
