Output voltage programming
Adding a resistor Rx between FB (pin L9) and SGND (L8) or between FB and VSENSE (pin
L2), it is possible to change the output voltage.
Connecting the resistor to SGND the output voltage increase (see
Connecting the resistor to VSENSE the output voltage decrease (see
Calculate the resistor for increasing output voltage with the following formula:
R
Calculate the resistor for decreasing output voltage with the following formula:
R
The module output voltage is 1.2 V with R

Additional loop compensation
If required by particular load condition, it is possible to change the feedback loop
compensation, adding a pole with an external R-C network between FB (pin L9) and COMP
(pin L10) (see
