Hello ADI/Linear folk!
We are planning to use the LT3579 x2 in a design that needs the following specs:
- Input voltage: Li-ion battery, 3.1V - 4.2V, but willing to consider ~3.4V - 4.2V.
- Output voltage ±12V
- output current per rail: 600mA
- output…
Hi,
For the LT3579 DC/DC converter I'm interested in the dual output as shown in the image below. I would like to be able to control the output voltage with 5V room (e.g. from 15V to 20V) with a DAC or digital pot. Would it be possible?
I tried adding…
I have designed SEPIC/CUK from ADISIMpower Excel Sheet with 2.7-4.5 Vin to +/-5.5 at 0.4A. Due to low ripple requirements and low Vstep, Output caps are large like 3x 100u for each.
Similarly, just for study purpose I simulated LT3579 SEPIC Converter…
In addition to this, you may want to try the LT3579 (LT3579 Datasheet and Product Info | Analog Devices).
The application you want is something like the one in page 36 of the datasheet.
The LT8364 has a guaranteed switch current of 4A. If used as a SEPIC for 5V out from a 3.0V source, the max load available will be about 1A. If this power is enough for you, the LT8364 should be fine. If not, the LT3579 is a much better option.
Hi Sss,
You may also want to check LT3863 and LT3579. These products also fit your given specifications.
Best Regards,
Alex
