ILED = VSET - 200mV

8 RFB

If VSET is 200 mV (typ.) the LED current is only determined by the internal offset voltages of the

comparators. To assure the switching activity is stopped and IOUT = 0, VSET has to be < 100 mV.

FIG.34 Analog Dimming

Soft Start Setting:

The soft start ramp is defined by a capacitor placed at the Soft_Start pin. Selection of the

capacitor can be done according to the following approximate formula. Vss_th_eff is the soft

start effectiveness threshold that depends on load condition. Its value is about 0.7 V for the

buck mode and 1.4 V for the boost mode
