7.3.2 Adjustable Output Voltage

The regulated output voltage (VOUT) can be programmed by connecting external resistors to FB pin. Calculate the feedback resistor values using Equation 1.

Equation 1. TPS7A6201-Q1 eq_vout_adj_lvsaa0.gif

where

  • VOUT = desired output voltage
  • VREF = reference voltage (VREF = 1.23 V typically)
  • R1, R2 = feedback resistors (see the Functional Block Diagram)

The overall tolerance of the regulated output voltage depends on the tolerance of internal reference voltage and external feedback resistors, and is given by Equation 2.

Equation 2. TPS7A6201-Q1 eq_tolvout_lvsaa0.gif

where

  • tolVOUT = tolerance of output voltage
  • tolVREF = tolerance of internal reference voltage (tolVREF = ±1.5% typically)
  • tolR1,tolR2 = tolerance of feedback resistors R1, R2

For a tighter tolerance on VOUT, select lower-value feedback resistors. TI recommends selecting feedback resistors such that the sum of R1 and R2 is between 20 kΩ and 200 kΩ.
