Design of DC-DC chip FB divider resistor circuit

Time:2024-04-07 Views:183
    In the use of DCDC chip circuit design will encounter the problem of calculating the partial voltage resistance, the following is a brief introduction to how to calculate
    The output voltage of the following circuit is Vout=1.8V
    Query the VFB voltage of the chip
    VFB voltage VFB=0.5V is found on the datasheet
    The calculation formula is as follows
    R1 usually uses adjustable resistors, 50K or 200K, etc. After R1 selects the value, R2 is calculated as follows:
