Hi
VIN=12V, LED= 10S x 6Ch, ILED/CH=160mA. VOUT=32.5V=3.2x10 + 0.5V
In this case how to calculate soft start time ?
Fig13 is showing 15ms and 200ms time. what is this condition ?

Hi
*Whch is correct ?
(Vout+VIFB(200mV))*R3/(R3+R4) or (Vout+VIFB(200mV))*R4/(R3+R4).
*Where comes from VIFB(200mV) value ?
*How to caluclate VOUT ?
VOUT= VF*N+VFB = VF*N+0.5
N is number of LEDs per strings, VFB is diode foward voltage
