CSD97394Q4M Description

Short technical summary and product information.

The CSD97394Q4M from Texas Instruments is a NexFET Power Stage designed for high-power, high-density synchronous buck converters. This device integrates a driver IC with NexFET technology to provide a complete power stage switching function. It achieves up to 90% system efficiency at 15A and can handle a maximum rated continuous current of 20A, with a peak current of 45A. The device supports high-frequency operation up to 2 MHz.

 

Key features include an ultra-low inductance package with a 3.5 x 4.5 mm footprint, optimized for system performance. It offers an ultra-low quiescent current mode, reducing current to 130 µA with the PWM input in tri-state, and down to 8 µA when SKIP# is held in tri-state. The CSD97394Q4M is compatible with 3.3V and 5V PWM signals and includes a selectable diode emulation mode for improved light-load efficiency. It operates with input voltages up to 24V and features integrated bootstrap diode and shoot-through protection.

 

The CSD97394Q4M is housed in an 8-VSON (3.5x4.5 mm) package, suitable for surface mounting. Its design is optimized for applications such as Ultrabook/Notebook DC/DC converters, multiphase Vcore and DDR solutions, and point-of-load synchronous buck converters in networking, telecom, and computing systems.
