TL497ACD datasheet by Texas Instruments

TL497ACD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TL497ACD can handle?
  The TL497ACD can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I ensure the TL497ACD is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a minimum ESR of 0.1 ohms. Also, keep the input and output capacitors close to the IC and use a good quality PCB layout.
• What is the maximum output current that the TL497ACD can provide?
  The TL497ACD can provide up to 1A of output current, but it's recommended to keep it below 0.8A for reliable operation and to prevent overheating.
• How do I adjust the output voltage of the TL497ACD?
  The output voltage of the TL497ACD can be adjusted by changing the ratio of the resistors R1 and R2 in the feedback network. A higher ratio will give a higher output voltage, and a lower ratio will give a lower output voltage.
• What is the purpose of the compensation pin (pin 7) on the TL497ACD?
  The compensation pin (pin 7) is used to add an external capacitor to improve the stability of the regulator. It's recommended to use a 10nF to 100nF capacitor between pin 7 and ground to ensure stability.
