DCP020509U Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane and a separate power plane for the DC-DC converter. The input and output capacitors should be placed close to the IC, and the feedback resistors should be placed close to the FB pin.
  • The inductor selection depends on the output current, switching frequency, and output voltage. A good starting point is to use an inductor with a value between 1.5uH to 3.3uH, and a saturation current rating above the maximum output current. The inductor should also have a low DCR (DC resistance) to minimize power loss.
  • The DCP020509U can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and minimize power loss.
  • The output voltage of the DCP020509U can be adjusted by changing the feedback resistors (R1 and R2) according to the formula: Vout = 0.8V * (1 + R2/R1). The resistors should be chosen to ensure a stable output voltage and minimize output voltage ripple.
  • The DCP020509U has a thermal derating of -1.5%/°C above 25°C. This means that the maximum output current will decrease as the ambient temperature increases above 25°C.
