The SP6652 is a high efficiency, synchronous buck regulator ideal for portable applications using one Li-ion cell, with up to 1A of output current. The 1.4MHz switching frequency and PWM control loop are optimized for a small value inductor and ceramic output capacitor for space constrained portable designs. The input voltage range of 2.7V to 5.5V, excellent transient response, output accuracy and ability to transition into 100% duty cycle operation extending the battery life makes the SP6652 a superior choice for a wide range of portable power applications. A logic level shutdown control, external clock synchronization and forced-PWM or automatic control inputs are provided. Other features include soft-start, overcurrent protection and 140°C over temperature shutdown.

Frequently Asked Questions
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.
