Product details
Overview
NCV6323FELMTW10TBG from onsemi is a 3 MHz, 1.6 A synchronous buck converter with fixed 1.0 V output voltage, optimized for automotive ADAS sub-systems powered from 2.8–5.5 V pre-regulator rails. It integrates high-side P-MOSFET (RON ≤ 250 mΩ at 3.3 V) and low-side N-MOSFET (RON ≤ 180 mΩ), delivers ±2% DC output voltage accuracy, and features Power Good (PG) monitoring and thermal shutdown at 150°C.
For engineers reviewing the NCV6323FELMTW10TBG datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (WDFNW8, 2×2 mm), confirmed pin functions (EN, PG, SW, FB, PVIN, AVIN, AGND, PGND), thermal performance data (θJA = 40°C/W on demo board), and automotive-grade reliability (AEC-Q100 qualified).
Technical Context
The NCV6323FELMTW10TBG implements voltage-mode PWM control with fixed 3.0 MHz switching frequency and integrated compensation. Its dual-MOSFET architecture uses complementary gate drive with built-in dead-time control to prevent shoot-through, enabling synchronous rectification without external diodes.
It operates across 2.8–5.5 V input range with UVLO rising threshold of 2.8 V (150 mV hysteresis), supports soft-start timing of 415 µs (TSS) and 502 µs (TSTART) per datasheet Figure 62/63, and provides open-drain PG output with 90% nominal VOUT trip point and 2.5% hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V ±2% DC accuracy over −40°C to +125°C junction temperature |
| Max Output Current | 1.6 A DC at TA ≤ 85°C; derated to 1.2 A at TA ≤ 105°C |
| Switching Frequency | 3.0 MHz ±10%; enables use of 1.0 µH inductor and compact 10 µF ceramic output capacitor |
| Input Voltage Range | 2.8 V to 5.5 V; supports direct connection to automotive 3.3 V or 5.0 V pre-regulator rails |
| Quiescent Current | 5.7 mA typical at no load, VOUT = 1.0 V, enabling low-power standby operation |
| Thermal Shutdown | 150°C threshold with 25°C hysteresis; protects against irreversible junction damage |
| Power Good Accuracy | Monitors VOUT at 90% nominal level (0.9 V) with 2.5% hysteresis for reliable system sequencing |
Pinout & Package
NCV6323FELMTW10TBG is housed in a wettable flank DFN-8 (WDFNW8) package: 2.0 × 2.0 mm body, 0.5 mm pitch, 0.8 mm max height, exposed thermal pad (EPAD) internally connected to AGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - PGND | Power Ground | High-current return path for switch node; requires local ground plane to minimize noise coupling |
| 2 - SW | Switch Node | Drives inductor; must be routed with short, wide copper to reduce EMI and conduction loss |
| 3 - AGND | Analog Ground | Reference for feedback and internal bias; connects to system ground at single point near EPAD |
| 4 - FB | Feedback Input | Direct connection to output rail near capacitor anode; critical for regulation stability and noise immunity |
| 5 - EN | Enable Control | Digital input (1.1 V high threshold); internal 5 µs filter prevents false triggering from noise |
| 6 - PG | Power Good Output | Open-drain signal; pulled low when VOUT < 0.9 V; requires external pull-up for system monitoring |
| 7 - AVIN | Analog Supply | Bias supply for control circuitry; bypassed with ≥1 µF ceramic capacitor to AGND |
| 8 - PVIN | Power Supply | Main input power rail; requires ≥10 µF ceramic capacitor directly to PGND for transient response |
| 9 - EPAD | Thermal Pad | Exposed copper pad soldered to PCB ground plane; essential for achieving θJA = 40°C/W |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q100 Qualified | Qualified to Grade 1 (−40°C to +125°C) with PPAP capability; validated for automotive ADAS camera and telematics applications |
| 3 MHz Fixed-Frequency PWM | Enables ultra-compact filter design: 1.0 µH inductor + 10 µF ceramic output capacitor meet ripple and transient requirements |
| Integrated Feedback Network | Eliminates external resistor divider; ensures precise 1.0 V output without calibration or layout sensitivity |
| Power Good with Hysteresis | Open-drain PG output asserts low when VOUT drops below 0.9 V, with 2.5% hysteresis preventing chatter during marginal conditions |
| Thermal Protection | 150°C shutdown with 25°C hysteresis and dedicated thermal characterization (θJC-BOT = 43°C/W) enable robust thermal management in space-constrained modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ2171GJ-AEC1-P | 2.5–5.5 V input, 1.0 A max, 2 MHz switching, adjustable output (external resistors required) | Lacks integrated feedback for fixed 1.0 V; lower current rating limits use in 1.2+ A camera ISPs | Select when adjustable output or lower cost is prioritized over 1.6 A capability and fixed-voltage simplicity |
| TPS62865ARGRR | 2.7–6.5 V input, 4 A max, 3.4 MHz switching, fixed 1.0 V, but not AEC-Q100 qualified | Higher current and wider VIN support, but unsuitable for automotive production without additional qualification | Select for industrial or non-automotive designs needing higher headroom or extended input range |
Compared with MPQ2171GJ-AEC1-P and TPS62865ARGRR, the NCV6323FELMTW10TBG uniquely combines AEC-Q100 qualification, integrated 1.0 V feedback, 1.6 A capability at 85°C ambient, and wettable flank packaging-making it the only drop-in solution for space-constrained automotive camera modules requiring zero-resistor configuration and PPAP compliance.

FAQ
What is the fixed output voltage of the NCV6323FELMTW10TBG?
The NCV6323FELMTW10TBG delivers a factory-trimmed fixed output voltage of 1.0 V with ±2% DC accuracy over −40°C to +125°C junction temperature, as specified in the Electrical Characteristics table (VOUT10_200mA = 0.985–1.015 V at 200 mA load). This eliminates need for external feedback resistors and ensures consistent core voltage for image sensors and processors.
Does the NCV6323FELMTW10TBG support automotive qualification standards?
Yes, the NCV6323FELMTW10TBG is AEC-Q100 qualified (Grade 1, −40°C to +125°C) and PPAP capable. Its qualification covers thermal cycling, humidity testing, and ESD robustness (HBM ±2 kV, CDM ±500 V), making it suitable for production deployment in front/rear camera modules and ADAS electronic control units.
What package type does the NCV6323FELMTW10TBG use, and why is it important?
The NCV6323FELMTW10TBG uses a WDFNW8 (wettable flank DFN-8) package: 2.0 × 2.0 mm, 0.5 mm pitch, 0.8 mm max height, with exposed thermal pad. The wettable flanks enable automated optical inspection (AOI) of solder joints, critical for automotive manufacturing yield; the low profile supports ultra-thin camera modules.
How does the Power Good (PG) function work on the NCV6323FELMTW10TBG?
The NCV6323FELMTW10TBG PG pin is an open-drain output that goes low when VOUT falls below 90% of nominal (0.9 V), with 2.5% hysteresis. During startup, PG remains low until VOUT reaches regulation; once stable, PG pulls high via external pull-up. Delay from EN rising edge to PG high is 1.1 ms (TDPGH1), ensuring clean system sequencing.
What are the key thermal characteristics of the NCV6323FELMTW10TBG?
The NCV6323FELMTW10TBG achieves θJA = 40°C/W on demo board due to its exposed thermal pad (EPAD) soldered to PCB ground plane. Junction-to-case bottom (θJC-BOT) is 43°C/W, and thermal shutdown activates at 150°C with 25°C hysteresis. These values are measured per JEDEC JESD51-3 and validated in the Thermal Information section (page 5).
