The XRP7725 is a quad channel Digital Pulse Width Modulated (DPWM) step-down (buck) controller. A wide 4.75V to 5.5V and 5.5V to 25V input voltage dual range allows for single supply operation from standard power rails.
With integrated FET gate drivers, two LDOs for standby power and a 105kHz to 1.23MHz independent channel to channel programmable constant operating frequency, the XRP7725 reduces overall component count and solution footprint and optimizes conversion efficiencies. A selectable Digital Pulse Frequency Mode (DPFM) and low operating current result in better than 80% efficiency down to 10mA load provides support for portable and Energy Star compliant applications. Each XRP7725 output channel is individually programmable down to a minimum 0.6V with a resolution of 2.5mV, and configurable for precise soft-start and soft-stop sequencing, including delay and ramp control.
The XRP7725 operation is fully controlled via an SMBus-compliant I2C interface allowing for advanced local and/or remote reconfiguration, full performance monitoring and reporting as well as fault handling.
Built-in independent output overvoltage, over temperature, overcurrent and undervoltage lockout protections insure safe operation under abnormal operating conditions.
The XRP7725 is offered in a RoHS compliant, “green”/halogen free 44-pin TQFN 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.
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.
