Description:Switching Voltage Regulators 4.3-V output voltage, synchronous boost converter with integrated LDO and VSUB active discharge 6-WSON -40 to 85
Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency layout guidelines, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
The selection of the inductor depends on the specific application requirements, such as the input voltage, output voltage, and output current. TI provides an inductor selection guide in the datasheet, and it's recommended to use an inductor with a high saturation current, low DC resistance, and high self-resonant frequency.
The TPS610987DSET is rated for operation up to 85°C ambient temperature, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation. TI provides a thermal derating chart in the datasheet.
To ensure EMC compliance, it's recommended to follow good design practices, such as using a shielded inductor, keeping the layout compact, and using a common-mode choke or ferrite bead on the input and output lines. TI also provides EMC guidelines in the datasheet.
The recommended input capacitor type is a ceramic capacitor with a value of 10uF to 22uF, depending on the input voltage and output current requirements. The capacitor should have a low equivalent series resistance (ESR) and be rated for the input voltage.
