The maximum input voltage that can be applied to the TPS72618DCQR is 5.5V, as specified in the datasheet. However, it's recommended to keep the input voltage below 5V to ensure reliable operation and to prevent damage to the device.
To ensure the output voltage is stable and accurate, make sure to follow the recommended layout and decoupling guidelines in the datasheet. Additionally, use a high-quality output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value (e.g., 10uF or higher) to filter out noise and ripple.
The minimum input capacitance required for the TPS72618DCQR is 1uF, as specified in the datasheet. However, it's recommended to use a higher capacitance value (e.g., 4.7uF or higher) to ensure stable operation and to filter out noise and ripple on the input voltage.
The TPS72618DCQR is rated for operation up to 125°C (TJ). However, it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure proper heat sinking and follow the recommended thermal design guidelines to prevent overheating and ensure reliable operation.
The output current capability of the TPS72618DCQR depends on the input voltage, output voltage, and ambient temperature. Use the following formula to estimate the output current: Iout = (Vin - Vout) / (Rds(on) * (1 + (ΔT / Tj))) , where Rds(on) is the on-state resistance, ΔT is the temperature rise, and Tj is the junction temperature.
