Other Parts Discussed in Thread: LM3102 Hello,
I would like to do something similar to what’s been described on this site a few times. I would like to produce +-5V from +-15V lines. I was going to use a LM3102 (or something similar) to produce +5V from…
Other Parts Discussed in Thread: LM3102 We did made some samples using the LM3102 part for wide range Input (8-36V) and fixed Output (5V). Our Circuit has a Super Capacitor ( to provide required burst current) . The overall design works good but the Inductor…
Other Parts Discussed in Thread: LM3102 , LM5009 , LM3100 Hi everyone,
we use the LM3102 voltage regulator for 5V and 3.3V supplies and are having quite a hard time with it. Below you can see the schematics of the 5V supply with some measurements in…
Other Parts Discussed in Thread: LM3100 , LM3102 , LMR24220 , LM3103 , LMZ14203H I'm looking at using the LM3100 for a 15V output buck converter. The IC selection matrix lists the maximum output voltage at 7V max (and the WEBENCH design tool won't let…
Part Number: LM25184 Other Parts Discussed in Thread: LM3102 , LMP8646 , TL431
Hello,
What's the lowest-parts-count way to add current limiting to the LM25184 standard circuit?
I don't want to eliminate the existing voltage regulation. I want…
Part Number: LM5146 Other Parts Discussed in Thread: LMP8646 , LM3102 Hi,
I have simulated LM5146 with below schematic for CV-CC operation . At 7A i am trying to enter in CC mode ,for me looks ok to me but this is with ideal OPAMP. Request the TI team…
Hello Sakhi,
As kai noted, the LMP8646 by itself does not limit the current. It simply measures the current through the shunt resistor. Alternatively, you could view the LMP8646 as a device that generates an output voltage based upon its gain setting…
Part Number: LM25085 Other Parts Discussed in Thread: LM3102 , LM25011 , LM3100 Hi, I have an urgent issue about the LM25085:
Circuit Description: LM25085, as the first-stage Buck chip, is connected to the supercapacitor through the MOS driven by the…
Part Number: LMP8646EB Other Parts Discussed in Thread: LM3102 , LMP8646 Hi, I'm working with LMP8646EB evaluation board suggest from TI engineer Amy Le with his very interest video, anyway connect and test the board something seem not to work properly…

Here are some comments/explanations.
First, the high frequency/spikes are noise pickup from probe, need to probe directly across a Vout capacitor for reliable measurement.
Low frequency ripple (<100mV) in no load condition is expected…
