Hi Sudarsh,

PWM (pin 4) is an input to our part and the input impedance is 1 Meg Ohm and the specification for this pin is on page 6 of the data sheet.

Thanks Tuan

Hi Sudarsh,

I do not fully understand your question here. I'll try to explain the DDRV output for you.

DDRV is the series dimming FET gate driver output that can connect directly to a external NFET for series dimming on the lo side or level shifted to drive a PFET for high side PWM'ing. Please section 7.3.8 for more explanation on this along with figure 22.

Thanks Tuan

Sir,I ask.pwm dimming without using ddrv pin output connect NFET or PFET. Pwm signal using gate pin dimming possible..?

Hi Sudarsh,

Please send a schematic to us for what you are trying to do. I still do not fully understand your question here.

Thanks Tuan
