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.
