LM5141RGER datasheet by Texas Instruments

LM5141RGER Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the LM5141RGER to minimize EMI?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output capacitors close to the IC. Additionally, the datasheet provides a recommended PCB layout and thermal pad connection.
• How do I ensure the LM5141RGER is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended component values and PCB layout. Additionally, the datasheet provides a stability analysis and a list of recommended components to ensure stability.
• What is the maximum input voltage that the LM5141RGER can handle?
  The LM5141RGER can handle up to 42V input voltage, but it's recommended to keep the input voltage below 40V to ensure reliable operation.
• Can I use the LM5141RGER in a high-temperature environment?
  The LM5141RGER is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It's recommended to use a heat sink or thermal pad to ensure reliable operation in high-temperature environments.
• How do I calculate the output voltage of the LM5141RGER?
  The output voltage of the LM5141RGER can be calculated using the formula: Vout = (1 + R2/R1) * Vin, where R1 and R2 are the feedback resistors, and Vin is the input voltage.
