CSD97376Q4M

The CSD97376Q4M from Texas Instruments is a highly optimized NexFET™ power stage for high-power, high-density synchronous buck converter applications. This integrated solution combines a driver IC with NexFET technology to provide a complete power stage switching function.

Key electrical specifications include a maximum continuous current rating of 20 A and a peak current rating of 45 A. It supports high-frequency operation up to 2 MHz, enabling smaller component sizes and improved system performance. The device achieves up to 90% system efficiency at 15 A load, with ultra-low quiescent current modes for improved light-load efficiency. It supports 3.3-V and 5-V PWM signals and features tri-state PWM input for reduced quiescent current.

Designed for ease of integration, the CSD97376Q4M utilizes a high-density 3.5-mm x 4.5-mm SON footprint with an ultra-low inductance package. The PCB footprint is optimized to simplify overall system design. It operates over a wide input voltage range of 4.5 V to 24 V and includes essential fault protection features like shoot-through protection and undervoltage lockout (UVLO).

Applications for this power stage include Ultrabook/Notebook DC/DC converters, multiphase Vcore and DDR solutions, and point-of-load synchronous buck converters in networking, telecom, and computing systems.
