Hi Yousuff,
R_LX means the resistance across LX and GND when main switch turned on. Please refer to below parameter from Section 6.5 Electrical Characteristics from the datasheet.

Part Number: LM3414HV Tool/software: Hi Steven,
The minimum inductor value calculation equation is incorrect on the datasheet.
Please see below screenshot:
VIN is 48V and not 35V as entered into the equation.
Can this please be amended and up-issued…

Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , TPS922052 , TPS922053 Hi,
about LM3414, on the datasheet i can read that thermal protection is 170°C, but in the absolute maximum rating, the Tj is 125°C
I think there is a mistake on…
Part Number: LM3414HV Other Parts Discussed in Thread: LM3414 , Hi,
Since the procurement of LM3414MR is not good, we are considering using LM3414HVMRX as an alternative product. When comparing the current values, it was confirmed that the LM3414HVMRX output…
It's an industrial, not an automotive, application. However, because the ambient temperature is often high, we tend to prefer automotive-grade parts. The LM3414HV is part of a potted module, which I've only partially reverse engineered. Some of the…
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 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…
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 , 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…
