Design Notes
For the TPS63710, select an inductor with a saturation current rating at least 20% higher than the peak switch current. The peak current depends on the input-to-output voltage ratio; for a 12V input and -5V output, the duty cycle is approximately 29%, and the peak current can be calculated using the datasheet formula. Use a low-DCR inductor to minimize losses and improve efficiency.
Place the input and output capacitors as close to the IC pins as possible to minimize parasitic inductance. Use a 10uF ceramic capacitor on the input and a 22uF ceramic capacitor on the output, with a 0.1uF high-frequency bypass capacitor. The exposed pad should be soldered to a large copper area for thermal dissipation, as the WSON package relies on the PCB for heat sinking.
Do not exceed the absolute maximum input voltage of 14V. Ensure the feedback resistor divider uses 1% tolerance resistors to maintain output voltage accuracy. The soft-start pin should have a capacitor to limit inrush current; omitting it can cause output overshoot. Also, verify the bootstrap capacitor is placed correctly for the high-side driver.
