TPS65263-1QRHBTQ1 Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65263-1QRHBTQ1 involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • When choosing output capacitors for the TPS65263-1QRHBTQ1, consider the output voltage, output current, and ripple requirements. A good starting point is to use ceramic capacitors with a capacitance value of 10uF to 22uF and a voltage rating of 2x the output voltage. The capacitor's ESR should be low enough to minimize voltage ripple.
  • The TPS65263-1QRHBTQ1 can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The output voltage of the TPS65263-1QRHBTQ1 can be adjusted by using a resistor divider network between the FB pin and the output voltage. The resistor values can be calculated using the formula provided in the datasheet.
  • The thermal derating curve for the TPS65263-1QRHBTQ1 is provided in the datasheet. It shows the maximum output current that the device can handle at different ambient temperatures. The curve is based on a maximum junction temperature of 150°C.
