ILD8150/ILD8150E LED driver IC for high power LEDs with hybrid dimming down to 0.5% Functional description
IOUT [A] ILED,AVG,TARG ILED,AVG,2 ILED,AVG,1 time [s] 0.025 0.025 tss
Figure 10 Digital soft-start Figure 10
shows the output current soft-start in case of 100% dimming or DIM pin open (internally pulled-up). IOUT [A] ILED,AVG,DIM ILED,AVG,2=ILED,AVG,ANA,MIN ILED,AVG,1 time [s] 5/fINPUT 5/fINPUT tss
Figure 11 Digital soft-start in dim-mode Figure 11
shows the output current soft-start in case of PWM dimming signal applied at the DIM pin. Note: Output current smoothing does not affect the output current for small variations of the dimming signal e.g. to create light fading effects.
