TPS60502DGS Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the input and output capacitors placed close to the device, and the feedback resistors placed close to the output pin. A star-ground configuration is also recommended to minimize noise and EMI.
  • To ensure stability, use a minimum output capacitance of 1uF, and ensure that the output capacitor's ESR is less than 1 ohm. Additionally, place a 10nF to 100nF capacitor in parallel with the feedback resistors to prevent oscillations.
  • Although the datasheet specifies a maximum input voltage of 5.5V, the device can handle up to 6V for short durations (less than 1 second) without damage. However, it's recommended to operate within the specified range for optimal performance and reliability.
  • The TPS60502DGS is rated for operation up to 125°C, but its performance may degrade at high temperatures. Ensure that the device is properly heatsinked, and consider derating the output current and voltage to prevent overheating.
  • The output voltage can be calculated using the formula: Vout = (R1 / R2) * (Vref - Vfb), where R1 and R2 are the feedback resistors, Vref is the internal reference voltage (1.2V), and Vfb is the feedback voltage (typically 0.8V).
