Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , LM3404HV Hi
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 I can measure a significant LED current overshoot during power up. The peak current is about 2.5A/50µs (Iset = 1A) with Vin=24V and a single LED (Vf=3V) for load.
As the number of LED is increased the peak current is reduced…
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 ?
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, Cout…
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 below…
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…
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 diode…
Part Number: LM3414HV Hello to all, Trying to figure out how to use the "foldback" feature on this part. Does anyone have component values for the reference circuit or have something that works? I'm trying to reduce the current automatically…
