Electrolytic + polymer = the hybrid capacitor

832
 0

Electrolytic capacitor is often a common reason for device failure and replacement is necessary. But what if we could combine the benefits of electrolytics and polymer capacitors. Now you can have the best of both worlds: hybrid capacitors from have been designed to combine the advantages of electrolytic capacitors with those of solid polymer capacitors.

The supplier claims the use of hybrid technology offers low leakage current and long life in combination with low ESR (20 mΩ) in miniature case sizes. The EEH-ZE series (Type V-ZE) hybrid components offer a nominal capacitance range of 33 µF up to 330 µF, at voltage ranges from 25 VDC up to 63 VDC, and feature an operating temperature range of -55°C up to 145°C, as well low ESR and high ripple current. So think about using a hybrid capacitor in your next power converter input/output filter, voltage regulator, or clock circuit.

Export Eagle Libraries With SnapEDA

1116
 0

Although the new Eagle subscription model by Autodesk will bring much-needed features to the software, many users after the announcement had decided to move their work to other alternatives, such as KiCad, Altium, Cadence, etc.

One of the challenges was to convert the libraries made by Eagle to be compatible with other software programs. SnapEDA solved that by offering a new free tool that translates Eagle libraries to KiCad, Altium, OrCad and other formats.

SnapEDA is a parts library for circuit board design provides free symbols, footprints, and 3D models for millions of electronic components. The goal behind SnapEDA is to build one trusted, canonical source of electronics design content that everyone can benefit from.

To convert your Eagle library just upload your file here, then you can re-download it in any format through your uploaded models page. The video below demonstrates the converting process:

Currently, all the uploaded parts will be public on SnapEDA until the private version is released. All parts are clearly marked as user-generated content and attributed to the uploader, and can be deleted at any time.

“We are big fans of Eagle and the new changes they’re making, and are confident that the subscription model will bring much-needed features to the software. But we also understand that it is (for many) a showstopper. Hopefully this free tool is helpful to those for whom this is the case.” – SnapEDA

 0

If your application requires a changing supply voltage, then this new IC is ideal for you. Intersil announced the ISL91128, a new buck-boost regulator. The new regulator has an I2C interface to select a broad set of features including output voltage range and slew rate. This eliminates the need of feedback resistors and allows the reuse of the same design for multiple output voltage needs.

The input voltage range is from 1.8V to 5.5V, and the output voltage range is from 1.9V to 5.5V with output current up to 2.2A. ISL91128 has 2.5MHz switching frequency. It is fully protected for short-circuit, over-temperature and undervoltage, according to the datasheet.

isl91128_applicationISL91128 is available in a small 2.15mm x 1.74mm WLCSP package.

intersil_bbIntersil provides ISL91128IIN-EVZ, an evaluation board for ISL91128. ISL91128 is part of ISL911xx family of buck-boost/boost regulators.

If you have a single Li-Ion battery powered application, then you need to think about using AS1383 in your design.

AS1383 is a DC-DC boost converter comes in a 6-pin WL-CSP package with 0.4mm pitch, a very small package suits the limited space applications. In the below image, you can compare the WL-CSP package with the 0805 SMD capacitor to know how small it is.

AS1383 And 0805 Capacitors
AS1383 And 0805 Capacitors

AS1383 uses 3.5MHz switching frequency and this high frequency allows the usage of a low profile inductor with only 1μH.

The input voltage range is from 2.7V to 5.5V and The output voltage range is from 2.7V to 5.0V with 200mA output current. It has an enable input pin to reduce the supply current to < 1μA.

AS1383 is available in three options:

  • AS1383-BWLT-AD an adjustable Vout version.
  • AS1383-BWLT-45 a 4.5V fixed Vout.
  • AS1383-BWLT-50 a 5.0V fixed Vout.

The output voltage in the adjustable version can be selected with external resistor divider connected to the FB pin.

The AS1383 price is 0.25$ for 1K order. Also, an evaluation Kit for AS1383 is available for 49$.

I obtained the schematic and the BOM from the evaluation kit manual.
