TDA3683
Multiple voltage regulator with switch and ignition buffer
• The output voltage of regulator 7 can be adjusted between 2.4 V and 10 V using two
external resistors (R1 and R2); see Figure 10. The following equation can be used for
global calculations to determine the output voltage at a given value of R1 and R2:
To meet an overall accuracy of 5 % the external resistors should have a 1 % tolerance
and the total resistance of the external resistors should have a value maximum 2 kΩ.
In the event that no external resistors are used the output voltage will be determined only
by the internal feedback resistors. The output voltage will be as follows: V
o
= 10 V (±5 %).
