ADVANCE INFORMATION
The output voltage of the LMR51635 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 10.2kΩ. 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 53.55kΩ, a standard value of 53.6kΩ is selected.
