Part Number: LM3410 Hi Support,
Please help clarify the output capacitor calculation with TI for the LM3410. The equation in page 20 doesn’t result in 1.9uF. Please clarify this.
Thanks.
Other Parts Discussed in Thread: LM3410XBSTOVPEV , LM3410 Hi,
My customer is evaluating LM3410 on EVM (LM3410XBSTOVPEV) and troubled by audible noise.
Could you tell countermeasure and what we should confirm?
Condition are followings;
- Noise…
Part Number: LM3410 Hi Team,
Our customer would like to use the following conditions(separate “VIN” and " regulation voltage(VREG)").
Because, Maximum VREG is 6.5V so this voltage is higher than the recommended operating conditions of VIN.
Could…
Hysteretic type converters do have other considerations, but the LM3410 is a constant frequency current mode converter. It also uses an output capacitor so the FB pin is really just regulating to a mostly DC signal of 190mV. So you do not want all of…
Part Number: LM3410 Hi,
I am testing on evaluation board LM3410XBSTOVPEV. I have replaced on board X type driver with LM3410Y type which has 525KHz switching frequency. And 3.3uH has been replaced with 100uH inductor.
I have set the feedback resistor…
Hey Clinton,
I tried your sugestion with a thick wire between Cout and the current sense ground, this showed massive performance improvement.
I looked closely to my design and found i have a break in the ground plane hidden with one of the component…
First of all it would be a good idea to use a 1A diode. The pulses each switch off cycle will be quite a bit more than 700mA but the average will be 700mA. You will have failures eventually and this might be the issue if it were to start leaking, it could…
Thanks John for quick reply. We have 50 PCB's in stock. We can do it for few PCB's but not for all. :( My question is is there any TI part with OPEN LED Fault Protection (similar to LM3410)? Or any other scheme with min changes?
( PS: To be very frank…
You can use the LM3410 in SEPIC configuration and there is an EVM already with the specs you need and it should be able to do 1A with a current sense resistor change (you may need to increase the output cap some for stability and may even need to reduce…
Other Parts Discussed in Thread: LM3410 Hi,
I use the LM3410X Constant Current Boost, to create a constant current of 225 mA (Rsense=0.83 ohm)
Inductor 10 uH/1A, test circuit as in datasheets
With an resistor as load the start-up, regulation etc…
