Key Differentiators
- Higher output voltage capability (40V) (vs TPS61040DBVR)
- Higher switch current (1A) (vs TPS61041DBVR)
- Wider input voltage range (2.7V-14V) (vs MIC2288YM5)
Design Notes
For optimal performance, keep the switch node (SW) trace short and wide to minimize parasitic inductance and capacitance. Place the input capacitor close to the VIN pin and the output capacitor close to the diode cathode. Use a solid ground plane to reduce noise and improve thermal performance.
Select an inductor with a saturation current rating higher than the peak switch current (1A) to avoid core saturation. A typical value is 10uH to 22uH for 1.6MHz operation. Use a Schottky diode with a reverse voltage rating above the output voltage and a current rating at least 1.5 times the average output current.
The SOT-23 package has limited thermal dissipation. For high output power, ensure adequate copper area on the PCB to dissipate heat. The junction-to-ambient thermal resistance is typically around 200C/W; calculate the power dissipation (approximately VOUT*IOUT*(1-efficiency)) and ensure the junction temperature stays below 125C.
