■ NOTES ON USE
1． Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be
2． Where wiring impedance is high, operations may become unstable due to the noise and/or phase lag depending on output
3. Phase compensation inside the IC is performed in the XC6216/XE6216 series. Therefore, an abnormal oscillation does not
4. Notes on Setting Output Voltage Externally (C type) Ta=25℃
●Setting Resistance-Dependant of XC6216 Series’ 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;
