Part Number: LM3549 Reg 0x14
Enables soft start feature and selects soft start time.
What is the purpose of the Soft Start feature? Why would I want a short Soft Start time? Why would I want to have any Soft Start time?
How does this effect the…
Part Number: LM3549 Reg 40h EEPROM CONTROL
When Reg 0x40 is set to 0x04 does the PROM get set with the default register values or does it clear the EEPROM (all zero/ones)?
Regards,

Part Number: LM3549 When I enable the chip (EN=H) how long must I wait for the chip to come alive? (How long does it take to get to Standby?)
How do I know when the part is ready for use? (EEPROM-> reg is complete,... I can now enable an LED)
Regards…
Part Number: LM3549 Reg 0x15
ILIMIT register sets the buck-boost converters current limit values.
The datasheet makes no mention of the use of these values? i.e. Why would I limit the current to 2Amps when the part can only deliver 700mA max?
Please…
Part Number: LM3549 Hi Team,
My customer's application is AR glasses. We use BRC to control the brightness while the R/G/B Iset are the same, but we found the color temperature are different in different brightness level.
Also, we tried to keep…
Part Number: LM3549 Other Parts Discussed in Thread: LP5036 Hi Team,
My customer would like to find a solution for gaming keyboard. The LED spec is as below picture. LM3549 is that I found the solution closest to the customer's needs. But its minimum…
Part Number: LM3549 Dear Sir/Ms.
My customer uses LM3549 to light up RGB LEDs, and the specifications are as follows. Max. 500mA / per ch, Min. 20mA/ Per ch. The circuit board was washed out, but found that the minimum output current can only reach…
Part Number: LM3549 Hello , I have an RGB LED which need 1.5 A total output current and each LEDs(R,B and G) needs different voltages. So I have decided to select LM3549 as driver IC. But the problem is that the maximum output current of the IC is 720…
Part Number: LM3549
Hello!
I am working with a customer who will be using this for a projection application like the chip is designed for. A few questions we have that aren't addressed in the datasheet:
What is the minimum on time for any particular…
