Design Notes
For optimal performance, place the input and output capacitors as close as possible to the VIN and VOUT pins. Use short, wide traces for high-current paths (SW, VIN, VOUT) to minimize parasitic inductance and resistance. The exposed pad (EP) should be soldered to a large copper area on the PCB to enhance thermal dissipation and provide a low-impedance ground connection.
Select an inductor with a saturation current rating higher than the peak switch current (5 A) to avoid saturation and efficiency loss. A typical inductor value for 1.5 MHz operation is 2.2 Β΅H to 4.7 Β΅H. Ensure the inductor has low DCR to minimize conduction losses. The output capacitor should have low ESR to reduce voltage ripple; a 22 Β΅F ceramic capacitor is recommended.
The TPS61230 can dissipate significant power at high load currents. Ensure adequate thermal relief by connecting the exposed pad to a large ground plane and using multiple vias to the bottom layer. The thermal resistance (ΞΈJA) of the VQFN-10 package is approximately 40Β°C/W; at 2 A output, power dissipation is around 0.5 W, resulting in a temperature rise of 20Β°C. For higher loads, consider the TPS61230A with lower RDS(on).
