- High efficiency up to 90% (vs TPS82695 (500mA))
- Low quiescent current of 17Β΅A (vs TPS82676)
Design Notes
Place the TPS826711 close to the load to minimize trace inductance and resistance. Use wide traces for input and output connections to handle the 600mA current. Ensure adequate ground plane for thermal and electrical performance. Follow the recommended layout in the datasheet for optimal performance.
Although the TPS826711 is highly efficient, at maximum load and high input voltage, power dissipation can be significant. Ensure the PCB has adequate copper area for heat dissipation. The MicroSiP package has a small thermal footprint, so consider thermal vias to a ground plane to improve heat spreading.
Do not exceed the absolute maximum input voltage of 4.8V. Ensure the enable pin is properly driven; floating it may cause unpredictable operation. Use appropriate input and output capacitors as specified in the datasheet to maintain stability. Avoid routing sensitive analog traces near the switching node to prevent noise coupling.
Compliance Information
