Part Number: LM3410 Other Parts Discussed in Thread: TPS61500 Hello,
i need a driver just like the LM3410, but with a higher switch current.
I want to drive a 10W LED (measured: 9,8V / 1A) with a single 18650 cell.
Part Number: LM3410 Hello Team,
While using LM3410, what will happen when feedback resistor will fail-open?
How to handle this condition so that device is not damaged?
Regards,
Mahendra.

Hi Support,
Using the LM3410 as the LCD backlight driver on the IVG, and attached is the switching voltage captured on the SW pin pin 6. The undershoot is below 0V by more than 3V.
Could you help to advise whether his would cause…
Part Number: LM3410 Hi, Could you tell me about LM3410 behavior when EN=High? Please confirm the attached file. LM3410.pdf After the EN pin ON, momentarily SW terminal will be OFF. Is this in the specifications? Could you give me your advice? Best Regards…
Part Number: LM3410 Other Parts Discussed in Thread: LM3405A , LM3405
Is it possible to create analog dimming with LM3410, by adding an analog offset to the feedback?
(see attached sketch)
The step-down LM3405A can be handled this way, but there…
Part Number: LM3410 Hello,
I build a boost driver using the typical boost application circuit from page 1 of the datasheet.
Given these inputs :
input voltage from 2.7V to 4.2V
output current : 750 mA at around 6.6 volts ( led in series)
Leds…
Part Number: LM3410 Hi, Customer is troubled to undershoot voltage of the SW pin. (-1V＠5ns to 10ns) Customers want to suppress undershoot voltage. Could you give me advice on the countermeasure circuit? For example, is it effective to insert a pF order…
Part Number: LM3410 Hello,
I have LM3410Y in my design with LCD backlight.
Parameters:
IN: 5V
OUT: 22Vmax @300mA LED
The IC is driven by PWM signal on DIM pin. Every rise edge of PWM cause over current situation. Screenshot below is inductor…
Other Parts Discussed in Thread: LM3410 Looking at the LM3410 datasheet, figure 32
Am I calculating correctly? The inductor mentioned in this example seems like it has too small of an Isat(1.1A) for the application… I calculate something closer to…
Other Parts Discussed in Thread: LM3410 , LM3429 Hi,
I'm checking my customer's circuit using LM3410.
However it seems that the input voltage may be higher than output voltage.
Can LM3410 work correctly above condition?
Or should I suppose buck…
