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 turn ON…
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 in…

Part Number: TPS92601-Q1 Other Parts Discussed in Thread: LM3421-Q1 , TPS92692-Q1 Hi Expert,
TPS92601-Q1 ia automotive headlights application, VIN max voltage is 40V in datasheet, but I search other multi-topology in headlights application VIN max is 65V…
LM3475 is not recommended for your application because VIN absolute maximum rating is 16V.

Hi Tuan,
I totally agreed with you that it is a system level. But I just want to check if the special device meets these standards. Anyway, thanks for your confirmation. And one more thing, my customer is considering on TPS92691-Q1 and LM3421-Q1 for this…
hi switch
Do you have any idea why customer does not use LM3409 or TPS92641? they are also buck controller that can provide current up to 5A. The reason is that LM3409 and TPS92641 are more popular and commonly used. So I am wondering if there is any specific…
Part Number: LM3421 Other Parts Discussed in Thread: TIDA-050002 Hi all, I try to reach a target of 3.6 Amps to supply a high power COB LED (LED voltage up to 38V) but I stay under 3 Amps. Do you have any idea?
As the input voltage is from 16V to 48V…
