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 I have a design which uses multiple LM3414HV channels, but they all need to be set to the same LED current, and that needs to be adjustable.
Can a common variable resistor or a resistor ladder with DIP switches, be used to feed the…

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 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 220V…
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.

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 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 , 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…
