The maximum input voltage that can be applied to the TPS61042DRBT 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 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 TPS61042DRBT 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 on the input voltage.
The TPS61042DRBT is rated for operation up to 85°C, but it's essential to consider the device's power dissipation and thermal resistance when operating in high-temperature environments. Ensure that the device is properly heat-sinked and that the junction temperature is kept below 125°C.
The output voltage of the TPS61042DRBT can be calculated using the following formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.21V), and R1 and R2 are the resistors used to set the output voltage.
