The maximum input voltage that can be applied to the TPS61058DRCR is 12V, but it's recommended to keep it below 10V to ensure reliable operation and to prevent damage to the internal components.
When choosing an inductor for the TPS61058DRCR, consider the inductor's value, saturation current, and DC resistance. A good starting point is to use an inductor with a value between 1uH and 10uH, and a saturation current that is at least 1.5 times the maximum output current. Also, make sure the inductor's DC resistance is low to minimize power losses.
The EN (enable) pin on the TPS61058DRCR is used to turn the converter on and off. When the EN pin is high, the converter is enabled and operates normally. When the EN pin is low, the converter is disabled and the output voltage is turned off. This pin can be used to implement power-saving modes or to shut down the converter when not in use.
To minimize noise and EMI with the TPS61058DRCR, follow good PCB layout practices such as keeping the input and output capacitors close to the IC, using a solid ground plane, and keeping the inductor and switch node traces short and away from sensitive analog signals. Also, consider using a shielded inductor and adding EMI filters to the input and output lines.
The minimum output capacitance required for the TPS61058DRCR is 10uF, but it's recommended to use a higher value such as 22uF or 47uF to ensure stable output voltage and to filter out ripple and noise.
