TLC7135CDW datasheet by Texas Instruments

TLC7135CDW Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the TLC7135CDW?
  The TLC7135CDW can operate from -40°C to 125°C, making it suitable for a wide range of applications.
• How do I ensure the TLC7135CDW is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the input and output pins with capacitors, and use a minimum of 10uF capacitor at the output pin. Also, ensure the PCB layout is well-designed to minimize parasitic inductance and capacitance.
• What is the maximum input voltage that the TLC7135CDW can handle?
  The TLC7135CDW can handle input voltages up to 15V, but it's recommended to operate within the specified range of 7V to 12V for optimal performance.
• Can I use the TLC7135CDW in a high-current application?
  The TLC7135CDW is designed for low-power applications, and its maximum output current is limited to 150mA. For high-current applications, consider using a different device or adding an external transistor to boost the output current.
• How do I adjust the output voltage of the TLC7135CDW?
  The output voltage of the TLC7135CDW can be adjusted by using a resistive divider network between the output pin and the adjust pin. The ratio of the resistors determines the output voltage, which can be calculated using the formula provided in the datasheet.
