TLC14CD datasheet by Texas Instruments

TLC14CD Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of TLC14CD?
  The TLC14CD can operate up to 100 kHz, but it's recommended to limit the frequency to 50 kHz for optimal performance and to avoid oscillations.
• How do I ensure stability and prevent oscillations in my TLC14CD circuit?
  To ensure stability, use a compensation capacitor (Cc) between pins 1 and 16, and a bypass capacitor (Cb) between pin 14 and ground. Also, keep the input and output capacitors as close to the IC as possible, and use a low-ESR capacitor for Cb.
• What is the minimum ESR required for the output capacitor (Cb)?
  The minimum ESR required for the output capacitor (Cb) is 0.5 ohms. Using a capacitor with a lower ESR can cause instability and oscillations.
• Can I use the TLC14CD as a voltage regulator?
  While the TLC14CD can be used as a voltage regulator, it's not recommended due to its limited current capability (up to 1.5A) and lack of short-circuit protection. Instead, consider using a dedicated voltage regulator IC.
• How do I calculate the output voltage of the TLC14CD?
  The output voltage (Vout) of the TLC14CD can be calculated using the formula: Vout = (1 + R2/R1) * Vref, where R1 and R2 are the feedback resistors, and Vref is the reference voltage (typically 2.5V).
