CSD87334Q3D Synchronous Buck NexFET™ Power Block  
1 Features  
3 Description  
The CSD87334Q3D NexFET™ power block is an  
optimized design for synchronous buck and boost  
applications offering high current, high efficiency, and  
high frequency capability in a small 3.3 mm × 3.3 mm  
outline. Optimized for 5-V gate drive applications, this  
product offers a flexible solution in high duty cycle  
applications when paired with an external controller or  
driver.
