The recommended PCB layout for the TPS5110PWR is to place the input capacitors (CIN) close to the VIN pin, and the output capacitors (COUT) close to the VOUT pin. Additionally, it is recommended to use a solid ground plane and to keep the high-current paths short and wide to minimize voltage drops and noise.
The selection of input and output capacitors for the TPS5110PWR depends on the specific application requirements. In general, it is recommended to use low-ESR capacitors with a high ripple current rating. The input capacitor should be able to handle the input voltage and current, while the output capacitor should be able to handle the output voltage and current. A good starting point is to use capacitors with a capacitance value of 10uF to 22uF and a voltage rating of 6.3V to 16V.
The maximum output current that the TPS5110PWR can deliver is 1A. However, the actual output current may be limited by the input voltage, output voltage, and the thermal performance of the device. It is recommended to check the device's thermal performance and to derate the output current accordingly to ensure reliable operation.
The output voltage of the TPS5110PWR can be adjusted by using a resistive divider network between the VOUT pin and the GND pin. The resistors should be chosen such that the output voltage is set to the desired value. The formula to calculate the output voltage is VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
The EN (enable) pin on the TPS5110PWR is used to enable or disable the device. When the EN pin is high, the device is enabled and the output voltage is regulated. When the EN pin is low, the device is disabled and the output voltage is turned off. The EN pin can be used to implement power sequencing or to turn off the device when it is not in use.
