Other Parts Discussed in Thread: LM3100 Hi everyone,
I am using F28M36P63C2 Concerto MCU and I had a short circuit between 3.3 V and gnd. I did a custom board taking into account the F28M36 evaluation board . I used the same schematics that the evaluation…
Other Parts Discussed in Thread: LMH0307 , LM3100 We have a design that uses the LMH0307 SDI cable driver. On our second batch of boards we have discovered that the SDI output pin (pin 12) on some of the cable drivers is shorted to the 3V3 supply rail. …
Good night Anston!!
I received the samples and I did the board with lm3100 --> 5V@1A - ok, LM3481 -> 18V@1A - ok, you sent me an schematic with cuk converter with lm3481, I did and without load the out is --> -18V, but when I put @500mA the…
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…
Other Parts Discussed in Thread: LM25575 , LM3100 , TPS54140A I'm using a LM25575 to deliver 3.3 Volts with a average load of 1A.
It's all ok, but if the load shrinks to aprox. 100 uA the input current is still 8mA.
Is there any possiblility to…
Other Parts Discussed in Thread: LM3100 , LM5574 I have been using the LM3100MH to convert 26V to 6.5V at 250mA in a textbook application for several years. Recently I am seeing a large number of regulators that have pins 4 and 5 (Vin) blown off the board…
hi Fabien,

After some more researching I found the datasheet of the LM3100 of National (which seems to be the same part). They suggest to connect EN to Vcc via a pullup-resistor and give a warning about not connecting any voltages exceeding 7V. If one closely examines…
