Product details
Overview
CSD95372BQ5MCT from Texas Instruments is a synchronous buck NexFET™ Smart Power Stage integrating driver IC and dual Power MOSFETs in a single VSON-CLIP (DMC) 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 frequency for high-density VR11.x/VR12.x voltage regulator applications in server and desktop CPUs.
For engineers reviewing the CSD95372BQ5MCT datasheet, CSD95372BQ5MCT pinout, CSD95372BQ5MCT application, or CSD95372BQ5MCT equivalent, key selection criteria include its integrated bidirectional current sensing with temperature compensation, tri-state PWM input compatibility, Diode Emulation Mode with FCCM control, and DualCool™ thermal performance in a 5 mm × 6 mm footprint.
Technical Context
The CSD95372BQ5MCT implements a high-frequency synchronous buck power stage with integrated gate driver, high-side and low-side NexFET™ MOSFETs, and analog current-sense amplifier (IOUT/REFIN). Its internal bootstrap diode, optimized deadtime control, and shoot-through protection enable robust operation up to 1.25 MHz.
It features analog temperature output (TAO/FAULT) with 600 mV at 0°C, fault monitoring for high-side short, overcurrent, and overtemperature events, and supports both forced continuous conduction mode (FCCM = HIGH) and diode emulation mode (FCCM = LOW) for light-load efficiency optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 60 A - Sustained phase current capability under VIN = 12 V, VDD = 5 V, VOUT = 3.3 V, fSW = 500 kHz, LOUT = 0.47 µH |
| Peak Output Current | 90 A - Short-duration (tp = 50 µs) current handling before thermal or overcurrent shutdown |
| Switching Frequency | Up to 1250 kHz - Enables compact magnetics and fast transient response in POL converters |
| System Efficiency | 93.4% at 30 A - Measured at VIN = 12 V, VOUT = 1.2 V, fSW = 500 kHz, LOUT = 0.225 µH, TA = 25°C |
| Power Loss | 2.8 W at 30 A - Total conduction + switching loss enabling low thermal rise in multiphase stacks |
| Junction-to-Board Thermal Resistance | 1.5 °C/W - Low RθJB enables direct PCB copper thermal spreading without heatsink in most layouts |
| Operating Junction Temperature | –55°C to 150°C - Supports industrial and server environments with extended thermal margins |
Pinout & Package
VSON-CLIP (DMC) package, 12-pin, 5 mm × 6 mm outline with exposed thermal pad (DualCool™ structure). Package height: 1.000 mm nominal; wettable flank side terminals for solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IOUT | Current sense amplifier output | Voltage proportional to phase current (IOUT – REFIN ∝ IPHASE); enables accurate real-time current monitoring |
| REFIN | Current sense reference input | External reference point for differential current sensing; sets zero-current baseline for IOUT |
| VDD | Gate driver supply | 4.5–5.5 V supply for internal driver logic and level-shifting; powers BOOT circuitry |
| ENABLE | Global enable control | Logic HIGH enables operation; internal 100 kΩ pulldown ensures safe default OFF state |
| PGND (pins 4, 13) | Power ground return | Dual PGND pins minimize ground loop inductance and improve current-sense accuracy |
| VSW | Switch node | Connects HS FET source and LS FET drain; ties directly to output inductor; critical for EMI and layout integrity |
| PWM | Tri-state PWM input | Logic HIGH → HS ON / LS OFF; Logic LOW → HS OFF / LS ON; High-Z → both FETs OFF after t3HT hold-off |
| FCCM | Mode select for conduction | LOW = Diode Emulation Mode (discontinuous); HIGH = Forced Continuous Conduction Mode (FCCM) |
| TAO/FAULT | Temp analog output / fault indicator | Analog voltage ∝ die temperature (600 mV @ 0°C); pulled to 3.3 V during thermal shutdown |
| BOOT & BOOT_R | Bootstrap supply path | Integrated bootstrap diode; BOOT_R is internal return to VSW; requires ≥0.1 µF ceramic capacitor |
| VIN | Main input supply | 16 V max input; connects to bulk capacitors; high dV/dt tolerance (27 V/10 ns) reduces snubbing needs |
| PGND (pin 13) | Secondary power ground | Second dedicated PGND terminal improves thermal and electrical separation for sensing paths |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck power stage applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CSD95490RWER | 60-A rated, but uses different MOSFET die (lower Qg), higher Rds(on) HS FET (1.7 mΩ vs 1.3 mΩ), no analog TAO output | Lacks temperature reporting and bidirectional current sense; suited for cost-sensitive VRs without telemetry | Choose when system-level thermal monitoring is handled externally and efficiency at 30–60 A is secondary to BOM cost |
| ISL99390HRZ-T | 60-A rated, integrated current sense, but no FCCM/Diode Emulation mode; fixed 5-V-only PWM interface | Requires external diode emulation circuitry; less flexible for light-load optimization in VR12.x systems | Prefer when using Renesas controllers with native ISL99xxx support and no need for tri-state PWM or analog TAO |
Compared with CSD95372BQ5MCT, CSD95490RWER trades telemetry and precision sensing for lower unit cost, while ISL99390HRZ-T offers comparable current capability but lacks the flexible conduction-mode control and analog thermal feedback essential for adaptive server VRs.

FAQ
What is the maximum switching frequency supported by the CSD95372BQ5MCT?
The CSD95372BQ5MCT supports up to 1250 kHz switching frequency, verified under recommended operating conditions with CBST ≥ 0.1 µF. This enables compact magnetic design and fast transient response in high-density VR applications. Operation above 1 MHz requires careful attention to PCB layout, gate drive strength, and thermal management to maintain reliability and efficiency. The CSD95372BQ5MCT's optimized deadtime and low-inductance package help sustain stable switching at these frequencies.
Does the CSD95372BQ5MCT require an external bootstrap diode?
No, the CSD95372BQ5MCT integrates a bootstrap diode internally-no external diode is needed. The BOOT and BOOT_R pins form a self-contained bootstrap circuit; a minimum 0.1 µF, 16 V X7R ceramic capacitor must be placed between them. This integration reduces component count, improves reliability, and eliminates routing complexity associated with discrete bootstrap diodes in high-frequency designs using the CSD95372BQ5MCT.
How does the current sensing work on the CSD95372BQ5MCT?
The CSD95372BQ5MCT provides bidirectional, temperature-compensated current sensing via differential inputs REFIN and output IOUT. The voltage difference (IOUT – REFIN) is proportional to phase current magnitude and direction. This analog output enables precise per-phase current monitoring and balancing in multiphase VRs without external amplifiers or calibration. The CSD95372BQ5MCT's sensing architecture maintains accuracy across –40°C to 125°C ambient, supporting dynamic load steps in CPU/GPU power delivery.
What thermal performance can be expected from the CSD95372BQ5MCT in a typical 4-layer board?
In a standard 4-layer PCB with 2-oz copper on inner layers and recommended land pattern, the CSD95372BQ5MCT achieves RθJB = 1.5 °C/W (junction-to-board). At 60 A continuous load, this yields ~85°C junction rise above board temperature-well within the 150°C max TJ rating. DualCool™ packaging enhances heat transfer through both bottom thermal pad and top-exposed clip, making the CSD95372BQ5MCT suitable for thermally constrained server and graphics card layouts without additional heatsinking.
Can the CSD95372BQ5MCT operate with a 3.3-V PWM signal?
Yes, the CSD95372BQ5MCT accepts 3.3-V and 5-V PWM signals natively. Its tri-state PWM input is compatible with common controller logic levels, and internal level-shifting ensures reliable gate drive regardless of PWM voltage. The ENABLE pin also functions correctly with 3.3-V logic, and the device includes internal pull-downs and current sources (e.g., 5 µA on FCCM) to ensure deterministic behavior when interfacing with 3.3-V microcontrollers or PMBus controllers-no level shifters required for CSD95372BQ5MCT integration.
