Other Parts Discussed in Thread: LM3409
Tool/software:
I am trying to design a LED DIMMING CIRCUIT using LM3409 HV
Vin 61 VDC
Vo 52 VDC
I LED 3.7 amps
this light is used for video / photography so there should be no visible ripple in the camera / recording instrument
PWM SIGNAL 40 Khz
MOSFET USED CMD 5950
Please suggest what should be an ideal value for the Fsw
KIndly suggest what inductor value i must select to get a linear variation , what percentage of 3.7 amps would be an ideal choice for the ripple current calculation
Also if you have any other suggestion please guide
