TL3844D Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for TL3844D is 8.5V to 40V. However, it can operate up to 45V with reduced performance.
  • The value of CT depends on the desired oscillator frequency. A higher value of CT results in a lower frequency. A good starting point is to use the formula: CT = 10nF to 100nF for frequencies between 20kHz to 200kHz.
  • The maximum output current that the TL3844D can handle is 1A. However, it's recommended to derate the output current based on the ambient temperature and the package type.
  • No, the TL3844D is not designed to be used as a voltage regulator. It's a pulse-width modulation (PWM) controller IC, and it's intended to be used in switching power supplies, DC-DC converters, and other applications that require PWM control.
  • To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet. Also, use a compensation network (R3, R4, C2, and C3) to stabilize the feedback loop. Additionally, ensure that the input voltage is well-regulated and decoupled.
