Key Differentiators
- Higher switch current (1A) compared to TPS61040/041 (400mA) (vs TPS61040)
- Wider input voltage range (2.7V-14V) vs TPS61040 (1.8V-6V) (vs TPS61040)
- Higher output voltage capability (40V) vs TPS61040 (28V) (vs TPS61040)
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 for 1.6 MHz operation. Use a Schottky diode with a reverse voltage rating above the output voltage and a current rating of at least 1A to handle the switch current.
The SOT-23 package has limited thermal dissipation capability. At high output power, ensure adequate copper area on the PCB to dissipate heat. The junction-to-ambient thermal resistance is typically 250Β°C/W; calculate the power dissipation and verify the junction temperature stays within the operating range.
