The maximum input voltage that can be applied to the TPS61085DGKT is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent damage to the device.
To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A minimum capacitance value of 10uF is recommended, and the capacitor should be placed as close to the output pin as possible.
The minimum input capacitance required for the TPS61085DGKT is 1uF, but it's recommended to use a higher capacitance value (e.g., 4.7uF) to ensure stable operation and to filter out noise and ripple on the input voltage.
The TPS61085DGKT is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's essential to ensure proper thermal management and to follow the recommended operating conditions to prevent overheating and damage to the device.
The output voltage of the TPS61085DGKT can be calculated using the following formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors connected to the FB pin, Vin is the input voltage, and Vref is the internal reference voltage (1.21V).
