Product details
Overview
NCV6324CMTAATBG from onsemi is an automotive-grade synchronous buck converter optimized for point-of-load regulation in portable and battery-powered systems. It delivers up to 2 A output current with externally adjustable voltage (0.6 V to VIN), operates at 3 MHz switching frequency, and features external MODE pin control for forced PWM or automatic PFM/PWM mode selection. It is used in USB-powered devices and smart phone subsystems requiring high efficiency and compact power delivery.
For engineers reviewing the NCV6324CMTAATBG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, WDFN8 wettable flank package, 2.5–5.5 V input range, active discharge function, and MODE-controlled power-save behavior - all critical for automotive infotainment and ADAS sub-rail designs.
Technical Context
The NCV6324CMTAATBG implements voltage-mode control with input feedforward compensation to maintain regulation across a wide 2.5–5.5 V input range. Its 3 MHz fixed-frequency PWM operation ensures minimal output filter size, while adaptive PFM mode at light loads improves light-load efficiency without compromising transient response.
It integrates complementary P- and N-channel MOSFETs with typical RON_H = 160 mΩ and RON_L = 110 mΩ at 3.6 V, enabling high-efficiency conversion. The MODE pin directly selects between forced PWM (high) and automatic PFM/PWM (low), distinguishing it from the PG-equipped NCV6324B variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V) and triple-cell alkaline/NiMH (3.6–4.5 V) battery inputs without external regulators. |
| Output Current | Up to 2.0 A - sufficient for powering ARM Cortex-A cores, LPDDR memory rails, or camera sensor modules. |
| Switching Frequency | 3.0 MHz (±10%) - enables use of ≤1.0 µH inductors and 10 µF ceramic output capacitors, reducing solution footprint by >40% vs. 1 MHz converters. |
| Feedback Reference | 600 mV (±1%) - sets output voltage via external resistor divider; allows precise 0.6 V to VIN adjustment with <±1% line/load regulation. |
| Quiescent Current | 5.7 mA (PWM mode, no load) - balances low-power standby and fast wake-up response in always-on subsystems. |
| Thermal Shutdown | 150 °C (typical) with 25 °C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |
| Enable Threshold | VEN_H = 1.1 V, VEN_L = 0.4 V - compatible with 1.8 V/3.3 V GPIOs and supports clean power sequencing in multi-rail systems. |
Pinout & Package
NCV6324CMTAATBG uses a space-saving 2.0 mm × 2.0 mm × 0.75 mm WDFN8 package (Case 511BE) with wettable flanks for automated optical inspection (AOI) and enhanced solder joint reliability in automotive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - PGND | Power Ground | Primary return path for high-current switch node; must be connected to system ground plane with low-inductance layout. |
| 2 - SW | Switch Node | Drives external inductor; carries high di/dt pulses; requires short, wide copper pour to minimize EMI and voltage overshoot. |
| 3 - AGND | Analog Ground | Reference for feedback, error amplifier, and internal bias; isolated from PGND except at single-point star connection. |
| 4 - FB | Feedback Input | Monitors output voltage via resistor divider; 600 mV reference enables precise output programming and stable loop compensation. |
| 5 - EN | Enable Input | Active-high digital control; internal 10 nA pull-down enables direct connection to microcontroller GPIO without external pull-down. |
| 6 - MODE | Mode Selection | Digital input to force PWM (≥1.1 V) or enable automatic PFM/PWM (≤0.4 V); replaces PG functionality of NCV6324B variant. |
| 7 - AVIN | Analog Supply | Powers internal analog circuitry; requires local 1 µF ceramic bypass capacitor placed adjacent to pin. |
| 8 - PVIN | Power Input | Main input supply rail; requires ≥10 µF ceramic capacitor with low ESL/ESR placed as close as possible to pin. |
| Exposed Pad | Thermal & Electrical Ground | Internally unconnected but must be soldered to system ground plane for thermal dissipation and noise reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated P- and N-MOSFETs eliminate external diode losses, achieving >90% efficiency at 1 A with 3.6 V input / 1.8 V output. |
| External MODE pin control | Enables deterministic PWM mode for noise-sensitive applications (e.g., audio codecs) or automatic PFM/PWM for battery runtime optimization. |
| Active output discharge | 500 Ω internal discharge path from SW to PGND when disabled, ensuring rapid output voltage decay (<1 ms) for safe power-down sequencing. |
| AEC-Q100 qualified | Qualified to Grade 1 (−40 °C to +125 °C junction), PPAP-capable, and manufactured in onsemi's automotive-dedicated site - suitable for front-camera, telematics, and body control modules. |
| Wettable flank WDFN8 | Facilitates automated AOI of solder joints on bottom terminations, improving manufacturing yield and field reliability in automotive production environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2164GQZ-P | 4.5–16 V input, 3 A output, 2.2 MHz, no MODE pin, no AEC-Q100 rating | Designed for industrial 12 V systems; lacks automotive qualification and wettable flank package | Select when higher input voltage and output current are required, and automotive compliance is not mandatory. |
| TPS62864DLCR | 2.7–6.5 V input, 4 A output, 4 MHz, I2C programmable, QFN-16 package | Offers digital control and higher current; larger footprint and no MODE pin for analog mode selection | Choose when programmable voltage, telemetry, or >2 A output is needed - at cost of increased BOM complexity and layout area. |

FAQ
What is the function of the MODE pin on the NCV6324CMTAATBG?
The MODE pin on the NCV6324CMTAATBG selects the converter's operating mode: a logic-high signal (≥1.1 V) forces continuous PWM operation, while a logic-low signal (≤0.4 V) enables automatic PFM/PWM mode switching to optimize efficiency across load conditions. This distinguishes NCV6324CMTAATBG from the NCV6324B variant, which uses the same pin for Power Good output instead.
Does the NCV6324CMTAATBG have Power Good (PG) functionality?
No, the NCV6324CMTAATBG does not include Power Good functionality. Its pin 6 is designated as MODE for external mode selection. Power Good is exclusive to the NCV6324B variant (e.g., NCV6324BMTAATBG), where pin 6 serves as an open-drain PG output. Using NCV6324CMTAATBG in a design expecting PG signaling will require external monitoring circuitry.
What package type and dimensions does the NCV6324CMTAATBG use?
The NCV6324CMTAATBG uses a WDFN8 package (Case 511BE) measuring 2.0 mm × 2.0 mm × 0.75 mm with 0.5 mm pitch and wettable flanks. The exposed thermal pad must be soldered to the PCB ground plane to ensure proper thermal performance and mechanical reliability, especially under automotive thermal cycling conditions.
Is the NCV6324CMTAATBG suitable for automotive applications?
Yes, the NCV6324CMTAATBG is explicitly qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C junction temperature) and is PPAP-capable. Its NCV prefix denotes automotive-specific process controls, test coverage, and change management - making it appropriate for front-camera modules, telematics control units, and body electronics where functional safety and long-term supply stability are required.
What is the recommended output capacitor value for the NCV6324CMTAATBG?
The NCV6324CMTAATBG is optimized for a 10 µF ceramic output capacitor (X5R/X7R, 0603 or 0805 case) in combination with a 1.0 µH inductor. This combination yields ~50 kHz double-pole frequency, matching the internal compensation network. For lower ripple, parallel 10 µF + 4.7 µF capacitors are validated; values below 7 µF may compromise loop stability per the datasheet's recommended operating conditions.
