Product details
Overview
NCV3063PG from onsemi is an automotive-grade monolithic DC-DC switching regulator supporting step-down, step-up, and inverting topologies with 1.5 A internal Darlington switch, 150 kHz oscillator frequency, 1.25 V ±2% precision reference, and thermal shutdown at 160°C. It operates from 0–40 V input and targets cost-sensitive power conversion in vehicle subsystems.
For engineers reviewing the NCV3063PG datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, confirmed automotive temperature range (−40°C to +125°C), real-world efficiency data (up to 85.5% in boost), and two rigorously cross-checked alternative parts for design continuity.
Technical Context
The NCV3063PG implements a hysteretic gated-oscillator control architecture with cycle-by-cycle current limiting via a 200 mV peak-sense threshold and internal thermal shutdown with 10°C hysteresis. Its Darlington output stage supports up to 40 V VSWCE and 1.5 A continuous switch current.
It integrates a temperature-compensated 1.25 V reference (±2% over −40°C to +125°C), comparator with 100 nA bias current, and oscillator timing capacitor interface (Pin 3) enabling frequency setting from ~110–190 kHz depending on CT. The exposed pad must be connected to GND for thermal performance and EMI control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0 V to +40 V - supports wide automotive battery transients including cold-crank (≥4.5 V) and load-dump (≤40 V). |
| Switch Current Rating | 1.5 A - enables direct drive of medium-power converters without external MOSFETs in many applications. |
| Oscillator Frequency | 150 kHz (typ.) - balances efficiency, component size, and EMI; adjustable via timing capacitor (CT = 2.2 nF typical). |
| Reference Voltage | 1.25 V ±2% - ensures stable feedback across full automotive temperature range (−40°C to +125°C). |
| Current Limit Threshold | 200 mV (typ.) - sets peak switch current via external sense resistor (RSC = 0.15 Ω yields ~1.33 A limit). |
| Thermal Shutdown | 160°C activation with 10°C hysteresis - protects against sustained overload or poor heatsinking without latch-up. |
| Junction Temperature Range | −40°C to +125°C - qualified per AEC-Q100 for under-hood and infotainment power rails. |
Pinout & Package
NCV3063PG is supplied in Pb-free SOIC-8 (Case 751) package with exposed pad (EP) requiring connection to GND (Pin 4) for thermal and electrical integrity. Pin 8 is not connected (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SWC) | Switch Collector | Collector of internal Darlington transistor; connects to inductor/switching node in buck/boost/inverting topologies. |
| 2 (SWE) | Switch Emitter | Emiter of internal Darlington; serves as return path for switch current and gate drive reference for external transistor configurations. |
| 3 (TCAP) | Timing Capacitor | Oscillator timing input; charges/discharges via internal 1:6 current ratio to set fOSC; max voltage 1.4 V. |
| 4 (GND) | Ground | Common reference for all internal circuits and exposed pad anchor point; mandatory for thermal dissipation. |
| 5 (COMP) | Comparator Inverting Input | Feedback node for output voltage regulation; connected to resistor divider from VOUT to set regulated voltage. |
| 6 (VCC) | Voltage Supply | Main power input (0–40 V); powers internal circuitry and drives external components like Schottky diodes. |
| 7 (IPK) | Ipk Sense | Peak current sensing input; monitors voltage drop across RSC to enforce cycle-by-cycle current limiting. |
| 8 (N.C.) | No Connect | Internally unconnected; must remain floating or tied to GND per layout guidelines - no functional role. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | NCV prefix indicates AEC-Q100 compliance and controlled change management for safety-critical systems. |
| Triple topology support | Single IC implements buck, boost, and inverting converters - reduces BOM count and simplifies platform design. |
| Cycle-by-cycle current limiting | Prevents switch failure during short-circuit or overload by terminating conduction each oscillator cycle above 200 mV sense threshold. |
| Internal thermal shutdown | Self-protecting operation at 160°C with 10°C hysteresis avoids catastrophic failure while allowing recovery at ≥150°C. |
| Pb-free SOIC-8 with EP | Exposed pad improves thermal resistance (RJA = 180°C/W) and EMI performance; requires GND tie-down per layout rules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC-DC controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV3063DR2G | Same die, identical SOIC-8 package and pinout; differs only in tape-and-reel packaging (2500 pcs vs. NCV3063PG's tube format). | No functional difference; suitable for automated SMT assembly where reel feed is required. | Select NCV3063DR2G for high-volume production lines using pick-and-place machines. |
| NCP3063BDR2G | Industrial-grade variant (0°C to +70°C), same electrical specs but lacks AEC-Q100 qualification and automotive change control. | Not approved for automotive use; acceptable in industrial or consumer power supplies where extended temperature is not required. | Choose NCP3063BDR2G only for non-automotive designs - NCV3063PG remains mandatory for vehicle applications. |
Compared with NCV3063DR2G, NCV3063PG offers identical performance in tube packaging for prototyping and low-volume builds, while NCP3063BDR2G provides cost savings outside automotive contexts but forfeits temperature rating and qualification traceability.

FAQ
What is the maximum input voltage supported by the NCV3063PG?
The NCV3063PG supports a maximum input voltage of +40 V on its VCC pin (Pin 6), making it compatible with automotive battery systems subject to load-dump transients. This rating is absolute maximum - sustained operation above 28 V should include thermal derating per the SOIC-8 RJA = 180°C/W specification. The NCV3063PG maintains regulation down to 0 V input, enabling cold-crank operation.
Does the NCV3063PG require an external MOSFET for 1 A output current?
No, the NCV3063PG integrates a 1.5 A Darlington switch capable of delivering up to 1 A continuously in properly heatsinked buck or boost configurations. Application data shows stable 800 mA output at 3.3 V (12 V input) and 350 mA at 24 V (12 V input) without external FETs. External transistors are optional enhancements for higher current (>1.5 A), higher efficiency, or wider input ranges - not required for basic 1 A operation. The NCV3063PG's internal switch eliminates gate-drive complexity in cost-sensitive designs.
How is the output voltage set on the NCV3063PG?
The NCV3063PG uses a resistor divider from VOUT to GND connected to Pin 5 (COMP), with the internal 1.25 V reference (±2%) serving as the regulation threshold. Output voltage is calculated as VOUT = 1.25 V × (1 + R1/R2), where R1 connects to VOUT and R2 connects to GND. For example, R1 = 2.4 kΩ and R2 = 3.9 kΩ yields 3.3 V. The NCV3063PG's comparator input bias current (±1000 nA) ensures minimal divider error - critical for automotive-grade accuracy.
What is the purpose of the exposed pad on the NCV3063PG SOIC-8 package?
The exposed pad beneath the NCV3063PG SOIC-8 package must be soldered to a GND plane to serve dual roles: (1) thermal dissipation - reducing junction-to-air thermal resistance (RJA) from 180°C/W to ~120°C/W with proper copper area, and (2) EMI suppression - providing low-inductance return path for high-frequency switch currents. Per onsemi layout guidelines, the pad connects directly to Pin 4 (GND) and requires ≥4 thermal vias to inner ground layers. Failure to connect the pad degrades both thermal performance and noise immunity in the NCV3063PG.
Can the NCV3063PG be used in a voltage-inverting configuration?
Yes, the NCV3063PG is explicitly designed for voltage-inverting (negative-output) applications, as confirmed by Figure 22 in its datasheet. In this topology, the internal switch controls current through an inductor, and a Schottky diode (e.g., 1N5819) steers energy to a negative output capacitor. The NCV3063PG achieves −12 V @ 100 mA from +5 V input with 49.8% efficiency and <300 mVpp ripple. Feedback is applied to Pin 5 using a resistor divider referenced to the negative rail, maintaining regulation accuracy across the −40°C to +125°C automotive range.
