Texas Instruments provides a recommended layout and placement guide in the TPS65279 datasheet, which includes guidelines for component placement, thermal vias, and PCB routing to ensure optimal performance and thermal management.
The TPS65279VRHHR is a configurable power management IC, and the output voltage can be set using external resistors. Texas Instruments provides a voltage selection guide in the datasheet, which includes a formula to calculate the required resistor values for the desired output voltage.
The TPS65279VRHHR has an absolute maximum input voltage rating of 18V, but the recommended operating input voltage range is 2.7V to 15V. Exceeding the absolute maximum rating can damage the device.
The TPS65279VRHHR has a built-in power sequencing feature that allows for controlled startup and shutdown of the output rails. Texas Instruments provides application notes and examples in the datasheet and related documentation to help implement power sequencing in various applications.
The TPS65279VRHHR has a thermal junction-to-ambient resistance (RθJA) of 30°C/W. To ensure proper thermal management, it is recommended to use a heat sink, thermal vias, and a PCB design that allows for good airflow and heat dissipation.
