AEC-Q100 Qualified 600mA High Voltage Adjustable Current Regulator with Enable Control
Data Sheet


The XR46004-Q is a high voltage, low dropout current regulator of output current up to 600mA in maximum. Users can adjust the output current from 100mA to 600mA through an external resistor, RSET, which gives users flexibility in controlling the light intensity of the LEDs. Further, the LED brightness is adjustable via the OE pin with a Pulse Width Modulation signal.
The thermal protection function protects the IC from over temperature damage. Also, the exposed thermal pad enhances the package power dissipation.

Frequently Asked Questions

The best way to determine this is to go to maxlinear.com and type the part into the search function. At or near the top of the results you should see something that looks like:

In this example, we looked for XRA1201. Click on part number header or on the link at the bottom of the result.  This brings you to the product page. For example:


Click on Parts & Purchasing, highlighted with the blue arrow above. The screen changes to:


Notice the status column and the “Show obsolete parts” link.  A legend tells you the definition of the different statuses. Click on the “Show obsolete parts” link to see EOL or OBS part numbers along with the Active part numbers, the legend still present:


Another method to find out if a part is OBS or EOL is to click on SUPPORT at the top:


And then Product Change Notifications:


Type the part into the search, and click on one of the part numbers from the drop down menu. Then you can look for the Product Discontinuation Notice, which generally is at the top of the list, for example:


If you see this, it tells you that this particular orderable part has been discontinued and when the last order date is, or was. If you click on the file, then you can view the notice we sent about this if you purchased the part in the recent past. It may also advise of a replacement part. When an orderable part first becomes discontinued, Product Discontinuation Notices are sent are sent to those who have purchased the parts in the recent past, if purchased directly, with a dated opportunity to place a last order.
