XRP7662

12A, 300kHz Step-Down Regulator
Data Sheet

Description

The XRP7662 is a synchronous voltage mode PWM step-down (buck) regulator capable of a constant output current up to 12Amps. A wide 5V to 22V single input voltage range allows for single supply operations from industry standard 5V, 12V and 18V power rails. Operations down to 3V are supported with an additional biasing voltage.

With a 300kHz constant operating frequency and integrated high and low side switch, the XRP7662 reduces the overall component count and solution footprint. In addition to a 1% output set-point accuracy, this device provides high efficiency, low ripple and excellent line and load regulation. An enable function and soft-start feature allow for controlled power up sequencing implementation.

Built-in current limiting, UVLO, output short-circuit and over temperature protection insure safe operation under abnormal operating conditions.

The XRP7662 is offered in a RoHS compliant, lead free 26-pin 7mm x 4mm DFN package.

Frequently Asked Questions

The best way to determine this is to go to exar.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. When you hover over it, it will turn grey and you can click anywhere in the grey box. This brings you to the product page. For example:

 
 

Click on Parts & Purchasing, highlighted in yellow 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:

 
 

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

 

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.
