The maximum input voltage that can be applied to the TPS61030RSAR 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 EN (enable) pin is used to turn the device on or off. To enable the device, connect the EN pin to VIN or a voltage higher than 1.4V. To disable the device, connect the EN pin to GND or a voltage lower than 0.4V. The EN pin can also be used to implement a power-saving mode or to sequence the power-up of multiple devices.
The output voltage of the TPS61030RSAR can be calculated using the following formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (1.2V), and R1 and R2 are the resistors connected to the FB pin. The output voltage range is from 1.2V to 5.5V.
The maximum output current that the TPS61030RSAR can deliver is 300mA. However, the actual output current may be limited by the input voltage, output voltage, and the internal power dissipation of the device.
