Hi,

Sorry, we don't provide the calculation tool. BTW, what parameters do you want to calculate?

BR,

Robin

Dear Robin, Thanks for your quick reply!!

In the Circuits Design for VCC= 48V

Output for LED for +29.12V / 10.36A

How to Cal. Resistor value of the IADJ, RON and CS use Resistor to match the Circuits .

Hi,

RON is used to set the switching frequency, please refer to section 8.2.1.2.3 and 8.2.2.2.3 of datasheet.

IADJ is used to set the current sense voltage, please refer to section 8.2.1.2.3 and 8.2.2.2.4 of datasheet.

CS is the current sense pin and once you have set the current sense voltage, you can calculate the Rcs= current sense voltage/10.36A. Rf can be set 1kOhm.

BR,

Robin
