CSD95373BQ5M

The CSD95373BQ5M from Texas Instruments is a highly optimized NexFET™ smart power stage for high-power, high-density synchronous buck converter applications. This device integrates the driver IC and power MOSFETs, enabling high-current, high-efficiency, and high-speed switching capabilities within a compact 5-mm × 6-mm outline package.

Key electrical features include a 45-A continuous operating current capability, achieving up to 92.7% system efficiency at 25 A with a low power loss of 2.6 W at the same current. It supports high-frequency operation up to 1.25 MHz and includes features like diode emulation mode with FCCM, temperature-compensated bi-directional current sense, and analog temperature output. Fault monitoring for high-side short, overcurrent, and overtemperature protection is also integrated.

The CSD95373BQ5M is compatible with 3.3-V and 5-V PWM signals and features a tri-state PWM input. It incorporates an integrated bootstrap diode and optimized dead time for shoot-through protection. The device is housed in a high-density SON 5-mm × 6-mm footprint with an ultra-low-inductance package, designed for system-optimized PCB layouts.

This smart power stage is suitable for multiphase synchronous buck converters, POL DC-DC converters, and synchronous converters for memory and graphic cards, as well as desktop and server VR11.x / VR12.x V-core and memory applications.
