■ NOTES ON USE
5. Torex places an importance on improving our products and its reliability.
4. Notes on setting output voltage externally (C type) Ta=25℃
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
●Setting Resistance-Dependant of XC6216 Series C type’s Output Voltage
The output voltage can be set externally by the following equation:
If the equation (3) is assigned to the equation (2), the equation becomes as below:
For this, the following equation can be used for setting output voltage externally:
And the equation (4) will be;
The second term of the equation (6), R
