Other Parts Discussed in Thread: TPS92510 Hi,
there is a question inSchnieder for TPS92510. they do some test with our EVM.
and they get some waveform. please see attached waveform.
The oscillogram of LED driver as following, 1. Normal oscillogram Test…
Other Parts Discussed in Thread: TPS92510 , LM3405 , LM3401 Hello
I'm looking for an LED PSU device with either internal or external FETs to power a 3.5V 700mA LED from a nominal 5V supply (so working down to 4.5V). It must be suitable for external shunt…
Hello Jenny,
For the LM3414HV: Low side MOSFET, no issue
For the TPS92510, from the datasheet: The TPS92510 is designed to operate up to 100% duty cycle as long as the BOOT to PH voltage is greater than 2.1V. If the BOOT capacitor voltage drops below…
Yeah since it is a protection type of mechanism in the LM5166, there is no loop that tightly regulate the current.
Unless you want to use a current sense resistor and drive your load like an LED

Part Number: TPS92511 Other Parts Discussed in Thread: LM3466 , , TPS92512 , TPS92513 , TPS92510 Hi,
Is it possible to use TPS92511 with LM3466?
If yes how would the LM3466 SEN and SRC pin be connected to the TPS92511?
Please see the below mockup. I am connecting…
Part Number: TPS92640 Other Parts Discussed in Thread: TPS92510 Tool/software: WEBENCH® Design Tools Hi everyone!
As for TPS92640, there are two questions.
Q1: WEBENCH simulation is not possible with TPS92640. Is TPS92640 not compatible with WEBENCH…
Hello,
Since Red, Amber, Green and Blue all have different forward voltage drops I would go with four separate converters, I probably would even if they were close. I would look at the TPS92510, TPS92513HV or the TPS92515HV depending on how fast you are…
The product line I work on only has boost switchers. Although it looked liek the TPS92510 is one of the best fit. I also saw the LM3405 which looks like it could work.
Thanks
Travis
Other Parts Discussed in Thread: LM46002 , TPS92510 , TPS92512 , TPS92513 This is the continuation of a discussion that started in the Simple Switcher forum. I asked about using the LM46002 as a constant-current LED driver, and was directed to this document…
