Hello Ilyas,
For your second question. Look at LM2735; a SOT23-5 device with a 2A / ~20V switch. (There are also other package choices.) I think if you put a capacitor voltage doubler on the switch node, you can get there. Most of our offerings will…
Hello Andreas,
it may be a layout issue, could you provide your layout?
You can also try to mount the LM27313 on a LM2731/3 EVAL BOARD since they are pin to pin compatible.
Regards,
Giuseppe
Hello Jeferson,
Please cosider also the LM2731
1. two version at 1.6MHz and 600kHz
2. ISW max 2A
3. smal package SOT-23
furthermore you can use WEBENCH for the selection.
Regards,
Giuseppe
Hello,
I agree that 90% efficiency is hard to reach from such a low input voltage. This application really begs for a synchronously rectified solution to reach that efficiency. But few such devices are available that support 12V output.( There might…
Other Parts Discussed in Thread: LMR62421 , LM3224 , LM2733 , LM2731 , LM27313 Hi,
I'm considering using the LMR62421 DC/DC converter in a design, requiring +/- 10V dual output rails. I was wondering if one can create the -10V rail in the exact same…
Hi Dave, WEBENCH is designing the circuit to work in Constant Current Mode which leads it to choose the large output cap for stability reasons. If you decrease the inductor value and work in discontinuous mode you can probably also get away with decreasing…
Hello Gamin,
You might also consider the LM2731 boost converters. I think you should just use a conventional boost topology to 10V output. Then rather than follow the boost with an LDO, just use a series resistor with a 1uF bypass cap to ground. Budget…
Hello Chad
Could you repost the EMG schematic in PDF, or tell me how to open a .TSC file? I'm interested in seeing your circuit. (I've designed these in the past.)
It sounds like you will need several supplies.
A) Supply one: That generates a +…
