Part Number: LM3404HV Hello. I cannot use the LM3404HV IC I bought from you efficiently. Can you help me with this? My e-mail address for contact: furkan@osaaydinlatma.com
Part Number: LM3404HV Other Parts Discussed in Thread: TPS92640 Hi Team,
We have received this inquiry from our customer,
I have string of LEDs, which can reach 900mA at 44.4V (measured). In our design with LM3404HVMRX/NOPB, no matter what values…
Hello,
Frequency mis-match between the switching frequency and PWM frequency shouldn't cause issues. What is probably happening is the LM3404HV is in an environment that causes it to run on the higher temperature side, this causes the RDSon to be higher…
Part Number: LM3404HV I am Roger Peterson with PMMI Lighting. We are currently prototyping LED drivers to replace the MeanWell LDD-1000H. We manufacture Smart Lighting Systems and our system is capable of running up to 160 led drivers, each controlling…
Part Number: LM3404HV Other Parts Discussed in Thread: LM3404 Hi support team, Please let us know about the specification and operation of the LM3404HVMR.
I am prototyping based on "Design Example 1" of the data sheet.
If the input voltage (24V) is…
Part Number: LM3404HV Other Parts Discussed in Thread: LM3404 , LM3404FSTDIMEV Hi,
We have worked with the now fairly old LM3404HV part for many years. Works fine. We also have dimmed using 20kHz PWM, also works fine.
Recently we have added one dimming…
Other Parts Discussed in Thread: LM3404HV , TPS92512 , TPS92513 Hi, how far can I push the LM3404HV? 60W? or is it set to 1A maximum. Can I run it at 1.4A constant current at 38V if I have good thermal management?
Best regards.
Marcos
Hello, What switching frequency are you running? (the part has a minimum off time). Have you watched the input voltage when it is doing this? The LM3404HV should be able to do this so getting as much information about your design will help. The person…
Part Number: LM3404HV Other Parts Discussed in Thread: LM3409 , LM3414HV , TPS92510 , TPS92513HV Hi e2e team,
I received a inquiry from a customer who used LM3404HV, and also made me confused about it.
The lm3404HV is used to output DC42 volts in…
Part Number: LM3404HVEVAL Other Parts Discussed in Thread: LM3404HV , LM3404 , TPS92515 Hello,
I need to design a simple constant current source which is not intended to drive LEDs but instead a water electrolysis.
I thought I could use the LM3404HV…
