The CSD95373AQ5M is a NexFET™ power stage module from Texas Instruments. It features a 12-pin SON (5x6mm) package and integrates a high-side and low-side MOSFET with a driver IC.
Key Functions:
- Inputs (PWM, Enable, VIN): Controls switching and operation.
- Power Stage: Combines two MOSFETs (synchronous buck topology).
- Bootstrap (BOOT): Powers the high-side driver.
- PHASE Node: Connects to the inductor.
- VIN (4.5V–18V): Supply voltage range.
- Thermal Pad (GND): Enhances heat dissipation.
Designed for high-efficiency DC/DC converters, it simplifies power supply designs.

The CSD95373AQ5M, a NexFET™ power stage, is primarily used in:
- Voltage Regulator Modules (VRMs): For CPUs, GPUs, and ASICs in servers, PCs, and data centers.
- Point-of-Load (PoL) Converters: Efficient power delivery in telecom, networking, and industrial systems.
- Embedded Systems: Power management in automotive, medical, and IoT devices.
- High-Frequency DC-DC Converters: Optimized for compact, high-efficiency designs.
Its integrated MOSFET and driver reduce footprint and improve thermal performance, making it ideal for space-constrained, high-performance applications.
