Product details
Overview
NCP4060AMNTXG from onsemi is a 30 V, 5 A synchronous buck DC-DC converter with integrated high- and low-side MOSFETs, 1.8 MHz fixed switching frequency, internal compensation, and ±1.5% output voltage accuracy over temperature and line/load conditions. It delivers up to 95% peak efficiency in compact 3 mm × 3 mm DFN-10 package for point-of-load regulation in industrial power supplies.
For engineers reviewing the NCP4060AMNTXG datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage range (4.5–30 V), output adjustability via external resistor divider (0.6 V to VIN), thermal shutdown, overcurrent protection, and enable control with precise 0.6 V threshold.
Technical Context
The NCP4060AMNTXG integrates dual PowerTrench® MOSFETs with RDS(on) of 22 mΩ (high-side) and 12 mΩ (low-side), enabling high-efficiency conversion without external gate drivers. Its current-mode PWM control architecture provides fast transient response and stable operation with ceramic output capacitors.
It supports forced PWM mode for low-noise operation across load range and includes internal soft-start (1.2 ms), power-good indicator, and hiccup-mode overcurrent protection. The device operates from –40 °C to +125 °C junction temperature and meets AEC-Q100 Grade 1 stress testing requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 30 V - supports wide industrial input rails including 12 V, 24 V, and unregulated battery-derived supplies. |
| Output Voltage Range | 0.6 V to VIN - adjustable via external resistor divider; enables precise core voltage regulation for microcontrollers and FPGAs. |
| Max Output Current | 5 A continuous - sufficient for powering SoCs, DSPs, and ASICs in space-constrained embedded systems. |
| Switching Frequency | 1.8 MHz fixed - allows use of small external inductors (typically 1–2.2 µH) and ceramic capacitors, reducing board area. |
| Output Voltage Accuracy | ±1.5% over line, load, and temperature - ensures reliable logic-level compliance for sensitive digital loads. |
| Thermal Shutdown | 150 °C with hysteresis - protects against sustained overload or poor heatsinking in sealed enclosures. |
| Enable Threshold | 0.6 V typical - compatible with standard GPIOs and logic-level control signals without level-shifting. |
Pinout & Package
Package: 3 mm × 3 mm, 10-pin DFN with exposed thermal pad (MN package code). Pin 1 marked by dot; thermal pad soldered to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Connects to main DC supply (4.5–30 V); requires local 10 µF ceramic bypass capacitor. |
| SW | Switch node | Drives external inductor; high dv/dt node requiring tight layout and minimal trace length. |
| VOUT | Regulated output | Delivers up to 5 A; connects directly to output capacitor and load. |
| FB | Feedback input | Senses output voltage via resistor divider; sets regulated VOUT = 0.6 V × (1 + R1/R2). |
| EN | Enable control | Active-high logic input; pulls below 0.3 V to disable converter and reduce quiescent current to 1.5 µA. |
| PG | Power-good indicator | Open-drain output asserts high when VOUT is within ±10% of target; used for system sequencing. |
| GND | Ground reference | Common return for power and signal paths; must be connected to thermal pad for thermal and electrical integrity. |
| NC | No connect | Pins 8 and 10 are internally unused; leave floating or tie to GND per layout best practice. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP2451DT-LF-Z (Monolithic Power Systems) | 36 V max input, 2 A output, 2 MHz switching, no PG output, different pinout. | Limited to lower-current applications; lacks power-good signaling for sequenced systems. | Choose when input voltage exceeds 30 V and PG is not required. |
| TPS54332DR (Texas Instruments) | 28 V max input, 3.5 A output, adjustable frequency (100 kHz–2.5 MHz), external compensation. | Requires additional compensation components; higher BOM cost and layout effort. | Prefer when design flexibility (frequency tuning, loop optimization) outweighs integration benefits. |
Compared with MP2451DT-LF-Z and TPS54332DR, the NCP4060AMNTXG offers higher output current (5 A), integrated PG signaling, and AEC-Q100 qualification-making it optimal for space-constrained, thermally demanding industrial and automotive point-of-load designs where reliability and simplicity are prioritized.

FAQ
What is the maximum recommended operating temperature for the NCP4060AMNTXG?
The NCP4060AMNTXG has a maximum junction temperature rating of +125 °C and is specified to operate continuously over –40 °C to +125 °C. Thermal derating begins above +105 °C ambient depending on PCB copper area and airflow; the device includes thermal shutdown at +150 °C with 20 °C hysteresis to prevent damage. For reliable long-term operation, keep TJ ≤ 125 °C using appropriate thermal pad soldering and copper pour.
Does the NCP4060AMNTXG require external compensation components?
No, the NCP4060AMNTXG features an internally compensated current-mode control loop. Only two external components-an output inductor and output capacitor-are required for basic operation. This eliminates the need for external compensation resistors and capacitors, reducing design time and BOM count while ensuring stability across all valid operating conditions.
Can the NCP4060AMNTXG be used in automotive applications?
Yes, the NCP4060AMNTXG is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C), making it suitable for automotive body electronics, infotainment power rails, and ADAS subsystems. Its integrated MOSFETs, power-good output, and thermal protection align with automotive functional safety expectations, though it is not ASIL-rated and should be used in non-safety-critical power domains.
What is the minimum output voltage achievable with the NCP4060AMNTXG?
The NCP4060AMNTXG has a fixed 0.6 V internal reference voltage at the FB pin, enabling output voltages as low as 0.6 V when configured in standard resistor-divider feedback. With proper layout and low-ESR output capacitors, stable regulation down to 0.6 V is achievable-sufficient for powering modern low-voltage cores such as ARM Cortex-M7 or RISC-V SoCs.
How does the power-good (PG) pin function on the NCP4060AMNTXG?
The PG pin on the NCP4060AMNTXG is an open-drain output that goes high (pulled up externally) when the regulated output voltage is within ±10% of its target value. It remains low during startup, fault conditions, or shutdown. This signal enables precise power sequencing in multi-rail systems-for example, asserting processor reset release only after stable VDD is established-without adding external monitoring ICs.
