Trim Function (continued)
Method 2: External DC Source
By connecting an external DC supply across P4 (Enable) and P3 (GND) through a limiting resistor Rt, (see Figure 5),
output voltage adjustment can also be achieved. Equation 3 provides the relationship between the External DC supply, Vt,
and Vo (where Vo is the desired output voltage).
Given: Rt = 10k
Vo Adjustment to Lower Voltages. This method does not limit the recommended lower Vo adjustment to 2% as
mentioned on previous sections re: Vo adjustment through external trim resistor.
Example:
Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).
Requiring to adjust the output voltage from Vo = 2.5V to 1.8V
Vo = 1.8V, Vr = 0.87V, R1 = 3.09k, R2 = 1.69k (from Table 1). Based on Equation (3), Vt = 3.0V.
Example:
Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).
Requiring to adjust the output voltage from Vo = 2.5V to 0.9V
Vo = 0.9V, Vr = 0.87V, R1 = 3.09k, R2 = 1.69k (from Table 1). Based on Equation (3), Vt = 5.9V.
Vo Adjustment to Higher Voltages
Example:
Module version: APC08G03-9 (3V to 6Vin, 2.5Vo).
Requiring to adjust the output voltage from Vo = 2.5V to 3.3V
Vo = 3.3V, Vr = 0.87V, R1 = 3.09k, R2 = 1.69k (from Table 1). Based on Equation (3), Vt = -1.84V.
If application of negative voltage is not desired, the limiting resistor Rt can either be changed to a lower value (Rt = 1k
,
such that Vt = 0.60V per Equation 3), or use Method 1.
