MxL7204

Dual 4A Power Module

Description

The MxL7204 power module is a complete dual 4A or single 8A output switch mode DC/DC power supply with an input voltage of 4.5V to 20V. It offers higher efficiency and improved thermal performance than the competition while matching pinout and functionality.
 
Power modules integrate the switching controller, power FETs, inductors and all supporting components.The MxL7204 supports two outputs each with an output voltage range of 0.6V to 5.0V, set by a single external resistor. Its high efficiency design delivers up to 4A continuous current (5A peak) for each output. Only a few input and output capacitors are needed.
 
The device supports frequency synchronization, multiphase operation, and output voltage tracking for supply rail sequencing. High Switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability.
 
Fault protection features include overvoltage, overcurrent and over temperature protection. The power module is offered in a space saving and thermally enhanced 15mm × 15mm × 2.82mm LGA package.

Frequently Asked Questions

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.

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.
