JAJSOR1D june 2022 – august 2023 LM5177
PRODUCTION DATA
The feedback voltage divider is found with Equation 19:
For the 16-V output, an upper resistor of 71.5 kΩ and a lower resistor of 4.7 kΩ have been selected.
Table 9-2 shows an overview of a possible selection for the feedback divider resistors over common output voltages.
