TLC2262AIPWR datasheet by Texas Instruments

TLC2262AIPWR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of TLC2262AIPWR?
  The maximum power dissipation of TLC2262AIPWR is 1.4W. However, it's recommended to keep the junction temperature below 150°C to ensure reliable operation.
• How do I choose the right output capacitor for TLC2262AIPWR?
  The output capacitor should be chosen based on the desired output voltage ripple, output current, and stability requirements. A general rule of thumb is to use a capacitor with a value between 10uF to 100uF, and a voltage rating of at least 2x the output voltage.
• What is the minimum input voltage required for TLC2262AIPWR?
  The minimum input voltage required for TLC2262AIPWR is 3.5V. However, it's recommended to use a minimum input voltage of 4.5V to ensure stable operation.
• Can I use TLC2262AIPWR in a high-temperature environment?
  Yes, TLC2262AIPWR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the device's power dissipation and output current at high temperatures.
• How do I layout the PCB for TLC2262AIPWR to minimize noise and EMI?
  To minimize noise and EMI, it's recommended to follow good PCB layout practices such as separating the power and ground planes, using a solid ground plane, and keeping the input and output capacitors close to the device. Additionally, use a shielded inductor and keep the switching node (SW) away from sensitive analog circuits.
