BD69830FV-GE2 - ROHM Semiconductor

BD69830FV-GE2 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 solid ground plane on the bottom layer, and to use thermal vias to connect the exposed pad to the ground plane. This helps to dissipate heat efficiently.
• How do I ensure stable operation with a high-ESR output capacitor?
  To ensure stable operation with a high-ESR output capacitor, it's recommended to add a small ceramic capacitor (e.g. 10nF) in parallel with the output capacitor to improve the overall ESR and reduce oscillation risk.
• What is the maximum allowed voltage on the EN pin?
  The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
• Can I use the BD69830FV-GE2 in a high-temperature environment?
  While the BD69830FV-GE2 is rated for operation up to 105°C, it's recommended to derate the output current and voltage to ensure reliable operation in high-temperature environments (above 85°C).
• How do I calculate the output voltage ripple?
  The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESR) / (fsw * Cout), where Iout is the output current, ESR is the output capacitor's equivalent series resistance, fsw is the switching frequency, and Cout is the output capacitance.
