BD6142AMUV-E2 - ROHM Semiconductor

BD6142AMUV-E2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the BD6142AMUV-E2?
  A good PCB layout for the BD6142AMUV-E2 involves placing the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
• How do I ensure the stability of the output voltage in the BD6142AMUV-E2?
  To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF, and to place the output capacitor close to the IC. Additionally, the output voltage can be stabilized by adding a 10nF capacitor between the FB pin and the output pin.
• What is the maximum input voltage that the BD6142AMUV-E2 can handle?
  The maximum input voltage that the BD6142AMUV-E2 can handle is 18V. Exceeding this voltage may damage the IC.
• How do I adjust the output voltage of the BD6142AMUV-E2?
  The output voltage of the BD6142AMUV-E2 can be adjusted by using a resistive divider network between the output pin and the FB pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
• What is the thermal derating curve for the BD6142AMUV-E2?
  The thermal derating curve for the BD6142AMUV-E2 is not explicitly stated in the datasheet, but it can be estimated based on the package thermal resistance (Rth) and the maximum junction temperature (Tj). A general rule of thumb is to derate the output current by 1% for every 1°C increase in temperature above 25°C.
