The SP34063A is a monolithic switching regulator control circuit containing the primary functions required for DC/DC converters.
This device consists of an internal temperature compensated reference, voltage comparator, controlled duty cycle oscillator with active current limit circuit, driver and high current output switch. This device was specifically designed to be used in buck, boost, and voltage-inverting applications with a minimum number of external components.
The SP34063A cis available in an 8-pin NSOIC package.
- Supply voltage: 3V to 36V
- Current limiting output switch current to 1.5A
- Adjustable output voltage
- Operation frequency up to 110kHz
- Low quiescent current
- Precision 2% reference
- Available in an 8-pin NSOIC package

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.
