Part Number: LM3429-Q1 Other Parts Discussed in Thread: LM3429 , TPS92691 , TPS92690 , TPS92692 Usually how we design a π EMI filter and how to choose the size, value of the inductor and capacitors? Do we design the EMI filter before finishing the schematic…
Other Parts Discussed in Thread: LM3429-Q1 Hi Team
TI LM3429-Q1 SPEC have show " The internal PWM controller is designed for adjustable switching frequencies of up to 2 MHz "
Could you help to check the PWM frequencise range are ? to 2Mhz ? ,
Part Number: LM3429-Q1 Hello,
I'm configuring my already built board using the LM3429-Q1 in the buck-boost topology with parallel LED strings. Baring any failed strings or thermal issues (I've solved those issues) here's my specs (My FET & Diode have…
Other Parts Discussed in Thread: LM3429-Q1 , LM3409HV-Q1 Hi Sir,
below is my conditions for design of LM3429-Q1. I just used WEBENCH for calculation, but it always showed the result by buck-boost topology. how can I setup it to obtain the result by…
Part Number: LM3429-Q1 Other Parts Discussed in Thread: LM3429 Hello,
I've designed a boost driver with the LM3429 that's to drive 4 strings of 16 LEDs/string (VF ranging 55V to 64V) from on 48VDC. The designed current range is 1.1A/string down to…
Hi Clint, thank you for wanting to help.
I can only give you a waveform from webench as I don't have the tools to capture that information from my prototype.
I was in a hurry yesterday and missed the schematic, sorry.
Here is it:

Hello,
Since I couldn't get reply yet, I post again about this. I can find the tpulse calculation from datasheet p.19 equation(26). Then, tpulse is 3us by my calculation on the below conditions. Thus, I can use this device with 3~10us on time.
Vin…
Other Parts Discussed in Thread: LM3429 I have some question fort LM3429 Dimming frequency.
What Hz can you input to in nDIM?
Can it input 10kHz into nDIM?
