Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , TPS92640 Hello guys,
One of my customers is interested in LM3414HV. But the device output current capability is 1A.
They want to drive 100V~150V Vf LED with higher current than 1A and…
Part Number: LM3414 Hi team,
Since LM3414 is not available, I am considering changing to LM3414HV. Is it possible to change from LM3414 to LM3414HV without changing the circuit?
Best Regards,
Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , LM3414HV is Current LED Driver and range from 350 ma to 1A for output current. If I add a resistor which is serial with LED, output current through LED will be changed, it will drop down…
Part Number: LM3414HV Hi all,
I'm working on a Board where we have 16 circuits with LM3414HV. Each circuit
is dirivng 3 LEDs the Input Voltage is 12V.
L1 is 100µH
ILED is 0.5A
D1 is 2A Vf 0.56V
I have tried 450 kHz for fsw what was aweful…
Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 Hi;
İ use LM3414 regulator. İ need input EMI fikter
My regulator spec is ;
input =48V DC , Output =Vmax=42V I=500mA
Could you help me what should i desgn for EMI filter ?

İ made design LM3414HV as datasheeet. There is a problem. İf i touch Riadj resistor with my finger output current a bit get high and remove it current get normal. What happeningg…
Part Number: LM3414HV What is the minimum current requirement for the DIM pin to operate, Also what is the minimum and maximum capacitance on the Dim pin. the mode of operation is PWM, Also is this, effected by the frequency used for dimming.

Hi,
I use the lm3414hv in a pwm dimmed application. When i drive it at 20 kHz pwm i get led light visible artifacts (flicker) during the dim process.
Led current is 580mA, fsw 295kHz, L 100 uH, Vin 48 V, Vled 28V, Cin 6,8 uF…
Part Number: LM3414HV Other Parts Discussed in Thread: TPS92512 , LM3414 , TPS92641 hi,
A question arose to whether it would be possible to parallel two (or more) LM3414HV led drivers.
Each LM3414HV would have its own current set resistor, freewheel…
Part Number: LM3414HV I am trying to use the LM314HV for a home lighting system where the Vf could be as low as 5.32 and as high as 44.3. Vin max would be 53 v. I led is 1000ma. After going through all the calculations, this does not seem to be possible…
