The maximum input voltage that can be applied to the TPS61027DRCRG4 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, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
The TPS61027DRCRG4 is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
The output voltage of the TPS61027DRCRG4 can be calculated using the formula: Vout = 1.21V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The recommended ratio of R1 to R2 is 1:1 for a 3.3V output and 2:1 for a 5V output.
The EN (enable) pin is used to turn the device on and off. When the EN pin is pulled high, the device is enabled and the output voltage is regulated. When the EN pin is pulled low, the device is disabled and the output voltage is disconnected from the input voltage.
