TL3843BP Frequently Asked Questions (FAQs)

  • The TL3843BP can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, make sure to follow the recommended component values and PCB layout guidelines in the datasheet, and add a compensation capacitor (CC) between pins 5 and 4.
  • The soft-start pin (SS) allows for a controlled startup of the converter, reducing inrush current and electromagnetic interference (EMI). Connect a capacitor from SS to GND to set the soft-start time.
  • Yes, the TL3843BP can be used in a synchronous rectification configuration, but it requires additional external components and careful design to ensure proper operation.
  • The output voltage (Vout) can be calculated using the formula: Vout = (R2 / R1) * (Vref), where R1 and R2 are the feedback resistors, and Vref is the internal reference voltage (2.5V).
