FEATURES
DESCRIPTION
The CSD87384M NexFET™ Power Block II is a
highly optimized design for synchronous buck
applications offering high current and high efficiency
capability in a small 5.0-mm × 3.5-mm outline.
Optimized for 5 V gate drive applications, this product
offers an efficient and flexible solution capable of
providing a high density power supply when paired
with any 5 V gate drive from an external controller or
driver.
