XRP7613

1.2A, 36V Step-Down High Brightness LED Driver
Data Sheet

Description

The XRP7613 is a non-synchronous step-down converter with integrated FET optimized to drive high power LEDs at up to 1.2A of continuous current. A wide 7.0V to 36V input voltage range allows for single supply operations from industry standard 12V, 18V or 24V power rails.

Based on a hysteretic PFM control scheme, the XRP7613 can operate at switching frequency of up to 1MHz and allows for small external components selection while providing very fast transient response and achieving excellent efficiency. The output current is programmable from 150mA to 1.2A through an external sense resistor.

Output current dimming is supported through an analog signal or PWM logic signal at up to 40kHz. A dynamic LED current thermal control further enhances the reliability of the end application by linearly reducing the LED current as temperature raises.

An open LED, LED short-circuit, over temperature and undervoltage lock out protection insures safe operations under abnormal operating conditions.

The XRP7613 is offered in RoHS compliant, "green"/halogen free 8-pin exposed pad SOIC package.

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.

Find the product page of the part that you want to get an evaluation board for and click on Parts & Purchasing. Example:

 

Find the icons under Buy Now or Order Samples:

 
 

Click on the Buy Now icon and see who has stock and click on the Buy button:

 
 
 

Alternatively, you can click on the Order Samples

 
 

If the icons are missing, then contact Customer Support.
