Part number: LTM8071IY
Input voltage (Vin): +5V
Output voltage (Vout): -9V, -4V
The data sheet includes [Table 1. Recommended Component Values and Configuration]. There is no example for the case where the output voltage (Vout) is '-9V, -4V'. There are no calculation formulas in the data sheet.
In the simulation program (LTpowerCAD II V2.7.5), only ['+' output voltage] is calculated.
*** inquiry ***
1. Is there a formula to calculate ['-' output voltage]?
Vout: -9V, -4V
2. Is there a way to calculate [ '-' output voltage ] in simulation?
