JAJSFC9B September 2017 – June 2018 TPS560430
UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The output voltage of the TPS560430 device is externally adjustable using a resistor divider network. The divider network is comprised of 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 22.1 kΩ. With the desired output voltage set to 5 V and the VREF = 1.0 V, the RFBT value can then be calculated using Equation 7. The formula yields to a value 88.4 kΩ, a standard value of 88.7 kΩ is selected.
