MagI3C Power Module

VDRM – Variable Step Down Regulator Module

For this power module a minimum value of 200µF is recommended to keep the loop stable.

In order to choose the value of the output capacitor, the following steps should be utilized:

1. Start with the minimum COUT recommended (200µF), essential for a stable operation.

2. Measure td.

3. Calculate the appropriate value of COUT for the maximum voltage drop Vdischarge allowed at a defined load step,

using the following equation (12), derived from equation (11):

COUT≥

∆IOUT∙td

2∙Vdischarge

(12)

4. As mentioned above, changing COUT affects also td. Therefore, step 2 and step 3 should be repeated to find the

best performance.
