PRODUCTION DATA
The output voltage of the LMR516xx-Q1 device is externally adjustable using a resistor divider network. The divider network is comprised of a top feedback resistor RFBT and bottom feedback resistor RFBB. Equation 7 is used to determine the output voltage of the converter:
Choose the value of RFBB to be 22.1kΩ. With the desired output voltage set to 5V and the VREF = 0.8V, the RFBT value can then be calculated using Equation 7. The formula yields to a value 116kΩ, a standard value of 118kΩ is selected.
