TL3843D-8 Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
  • To ensure stability, use a minimum output capacitor of 10uF, and ensure that the output capacitor's ESR (Equivalent Series Resistance) is less than 1 ohm. Also, use a minimum input capacitor of 10uF and ensure that the input voltage is within the recommended range.
  • The TL3843D-8 can provide up to 1.5A of output current, but this may vary depending on the input voltage, output voltage, and ambient temperature.
  • The output voltage of the TL3843D-8 can be calculated using the formula: Vout = Vref x (1 + R1/R2), where Vref is the internal reference voltage (2.5V), R1 is the resistance between the output and the adjust pin, and R2 is the resistance between the adjust pin and ground.
  • The thermal shutdown temperature of the TL3843D-8 is typically around 150°C to 170°C, but this may vary depending on the specific device and operating conditions.
