9.2.1.2.4 FB Voltage Divider for Adjustable Versions
The adjustable version of the LM53600RB-Q1 and LM53601RB-Q1 devices regulates output voltage to a level that results in the FB node being Vref which is approximately 1.0 V; see Section 7.5 Output voltage given a specific feedback divider can be calculated using the following equation:
Equation 2. 
See typical applications schematic for adjustable versions of the LM53600-Q1 and LM53601-Q1 devices. Since the value of RFBT is typically set by board leakage considerations, the above equation can be solved for RFBB, the remaining unknown:
Equation 3. 
Note that typically, 100 kΩ is used for RFBT.
