5 Summary

TPS61287 device can be used to create efficient Boost converter systems for many kinds of applications. The efficiency of these systems can vary based on the operating conditions of the system and BOM selection, especially the MOSFET selection. The data sheet parameters of the MOSFET need to be reviewed and considered carefully. Engineers must ensure the voltage of the MOSFET and current ratings exceed the application requirements with sufficient margin. Crucially, the dynamic parameters, particularly gate charge and capacitances, must be compatible with the gate drive strength of the controller and dead time to minimize switching losses and prevent shoot-through. Thermal calculations are mandatory to validate the reliability of the design. Utilizing the calculation tool for our TPS61287 devices streamlines this process, enabling a swift and preferred MOSFET choice, leading to efficient and robust boost designs.
