3 Description
The CSD87331Q3D NexFET™ power block is an
optimized design for synchronous buck applications
offering high-current, high-efficiency, and highfrequency
capability in a small 3.3-mm × 3.3-mm
outline. Optimized for 5-V gate drive applications, this
product offers a flexible solution capable of offering a
high-density power supply when paired with any 5-V
gate drive from an external controller/driver.
