Select the proper ratio of the two feedback resistors R_FB1and R_FB2based on the output voltage. Adding a

capacitor in parallel with R_FB1helps the system stability. Typically, use R_FB2≈10kΩ and determine R_FB1from

the following equation:

CC Current Setting

A7330 constant current value is set by a resistor connected between the I_SETpin and GND. The CC output

current is linearly proportional to the current flowing out of the I_SETpin. The voltage at I_SETis roughly 1V and

the current gain from I_SETto output is roughly 100000 (100mA/1μA). To determine the proper resistor for a

desired current, please refer to figure below.

Output Current vs. R_ISET

CC Current Line Compensation

When operating at constant current mode, the current limit increase slightly with input voltage. For wide input

voltage applications, a resistor R_Cmay be added to compensate line change and keep output high CC

accuracy, as shown figure below.
