Product details
Overview
CSD95378BQ5MT from Texas Instruments is a synchronous buck NexFET™ Smart Power Stage integrating driver IC and dual power MOSFETs in a single LSON-CLIP (DQP) package. It delivers 60-A continuous output current, achieves 93.4% system efficiency at 30 A (VIN = 12 V, VOUT = 1.2 V, fSW = 500 kHz), and supports up to 1.25 MHz switching for high-density POL DC-DC converters in server VR12.x and GPU power delivery.
For engineers reviewing the CSD95378BQ5MT datasheet, CSD95378BQ5MT pinout, CSD95378BQ5MT application, or CSD95378BQ5MT equivalent, key selection criteria include tri-state PWM compatibility, temperature-compensated bi-directional current sense, integrated bootstrap diode, fault monitoring (HS short/overcurrent/overtemperature), and 5 mm × 6 mm ultra-low-inductance footprint.
Technical Context
The CSD95378BQ5MT implements a high-speed synchronous buck power stage with integrated gate driver, control FET, and sync FET. Its architecture supports diode emulation mode via FCCM pin control and forced continuous conduction mode, enabling optimized light-load efficiency and transient response in multiphase VR applications.
It features analog temperature output (400 mV at 0°C), accurate current sensing referenced to REFIN, and active shoot-through protection via optimized dead time. The device operates with 4.5–5.5 V VDD supply and accepts 3.3-V or 5-V PWM inputs, making it compatible with TI's TPS40428 and other VR controllers.

FAQ
What is the maximum recommended switching frequency for CSD95378BQ5MT?
The CSD95378BQ5MT supports up to 1.25 MHz switching frequency with stable operation and validated thermal performance. At this frequency, the device maintains 93.4% efficiency at 30 A (VIN = 12 V, VOUT = 1.2 V) and requires appropriate gate drive strength and PCB layout optimization to manage switching losses. Operation above 1.25 MHz is not characterized and may compromise reliability or efficiency in the CSD95378BQ5MT.
Does CSD95378BQ5MT require an external bootstrap diode?
No, the CSD95378BQ5MT integrates a bootstrap diode internally, eliminating the need for an external component. A minimum 0.1-µF, 16-V X7R ceramic capacitor must still be placed between BOOT and BOOT_R pins to ensure reliable high-side FET turn-on. This integration reduces BOM count, improves reliability, and simplifies layout for the CSD95378BQ5MT.
How does the TAO/FAULT pin function in multiphase configurations with multiple CSD95378BQ5MT devices?
In multiphase systems, the TAO/FAULT pins of all CSD95378BQ5MT units are wire-OR'd together using their integrated ORing diodes. Only the highest die temperature among the phases pulls the shared node low; during thermal shutdown, the affected CSD95378BQ5MT pulls TAO to 3.3 V, signaling fault to the controller. This enables centralized thermal monitoring without additional circuitry for each CSD95378BQ5MT.
What is the purpose of the FCCM pin on CSD95378BQ5MT, and how should it be configured?
The FCCM pin on CSD95378BQ5MT selects between diode emulation mode (FCCM = LOW) for improved light-load efficiency and forced continuous conduction mode (FCCM = HIGH) for stable loop control under all load conditions. An internal 5-µA current source pulls FCCM to 3.3 V if left floating, defaulting to CCM. For VR12.x applications requiring FCCM, tie the pin to GND via a resistor; for VR11.x or fixed-frequency designs, leave it open or pull HIGH for CCM operation in the CSD95378BQ5MT.
Can CSD95378BQ5MT operate with a 3.3-V PWM input signal?
Yes, the CSD95378BQ5MT is explicitly designed for 3.3-V and 5-V PWM signal compatibility. Its PWM input threshold is logic-level compatible, accepting standard CMOS signals without level shifting. This ensures interoperability with TI's TPS40428, IR35201, and other contemporary VR controllers that output 3.3-V PWM, making the CSD95378BQ5MT suitable for mixed-voltage control environments.
