USR1021 Datasheet

3A SYNCHRONOUS BUCK REGULATOR  
 
 
 
DESCRIPTION
 
The UTC USR1021 is a high efficiency, 3A synchronous buck
regulator. The UTC USR1021 works from a 6V to 18V input
voltage range, and provides up to 3A of continuous output current
with an output voltage adjustable down to 0.8V.  
The UTC USR1021 comes in an SOP-8 packages and is rated
over a -40°C~+85°C ambient temperature range.
 
 
FEATURES
 
 
* 6V~18V operating input voltage range
