Part Number: LM3421 Other Parts Discussed in Thread: LM3423 , LM3423BS2LYEV Tool/software: Hello, Ti teams.
I intend to drive LEDs at 48 V and 1.2 A output via the LM3421 from a 24 V, 2.5 A input.
The LEDs are connected in series (15 LEDs × 2.8 V…
Part Number: LM3421 Dears,
Customer feedback that when they use the LM3421,then found the current is follow the voltage,attachfile is the schematic,pls kindly help to chekc it.
Thanks
Part Number: LM3421-Q1 Other Parts Discussed in Thread: LM3421 Hi team,
May I know the variance of continuous conduction switching frequency without Rt's variance and Ct's variance?
Best regards,

Part Number: LM3421 Hi Ti Team，
1， I use LM3421 to do a step-down parallel dimming. Figure 1 is my test PWM dimming and main switching waveforms. Is the following figure normal? The schematic diagram is refer to Figure 2
Figure 1：
Figure 2…
Part Number: LM3421 Hi ti team,
I tried to simulate the Boost Application circuit shown in the LM3421 datasheet but could not get a constant output.
I am sending you the simulation file and the obtained I_LED trace. It would be helpful if you could…
Part Number: LM3421 Dears,
I have an important customer who is looking for an LED controller that can provide boost/buck for common anode laser R/G/B.
Specific requirements are as follows:
1. The input voltage is 5V
2. The output voltage of R/G/B…
Part Number: LM3421-Q1 Other Parts Discussed in Thread: LM3421 Hi,
In my board I have two identical circuits that uses LM3421. The intention is to power up two chains of HBLED separately or simultaneously. My circuit was based on the circuit showed…
Part Number: LM3421-Q1 Hi,
I am using in a board the Boost driver circuit of the schematic showed here: https://1drv.ms/i/s!AhE6En32rx-MoJxQAjgxhmwvcS-G8w?e=F6BLIm There are two identical drivers sharing Vsystem bus.
It is working fine but when I…
