Key Differentiators
- Low 1/f noise due to filtered reference (vs TPS63700DRVR)
- Synchronous rectification for higher efficiency (vs LT8330)
- Wide input voltage range (3.1 V to 14 V) (vs TPS63700DRVR)
Design Notes
Place the input capacitor (10 Β΅F) close to the VIN pin and the output capacitor (22 Β΅F) close to VOUT. Use a solid ground plane and connect the exposed pad to the ground plane with multiple vias for thermal and electrical performance. Keep the switch node (SW) trace short and wide to minimize parasitic inductance.
The WSON package's exposed pad must be soldered to a copper area on the PCB to dissipate heat. For high output currents, ensure adequate copper area and thermal vias. The thermal resistance (ΞΈJA) is typically 40Β°C/W with proper layout; verify in the datasheet. At 1 A output, power dissipation can be significant, so monitor junction temperature.
Do not exceed the absolute maximum input voltage of 14 V. Ensure the inductor's saturation current rating is higher than the peak switch current. Use a Schottky diode across the inductor if the synchronous rectifier is not used, but the TPS63710 includes synchronous rectification, so an external diode is not needed. Verify the feedback resistor values for the desired output voltage.
