Product details
Overview
ADP3416JR-REEL from Analog Devices is a dual N-channel MOSFET driver optimized for synchronous buck converters, featuring bootstrapped high-side drive, integrated overlap protection, 7 V max VCC supply, 4 Ω typical high-side sourcing resistance, and 8-lead SOIC packaging. It enables efficient CPU core power delivery in mobile and desktop computing platforms.
For engineers reviewing the ADP3416JR-REEL datasheet, ADP3416JR-REEL pinout, ADP3416JR-REEL application, or ADP3416JR-REEL equivalent, key selection criteria include bootstrap-compatible high-side gate drive capability, shoot-through prevention via SW-node voltage monitoring, propagation delay matching between DRVH/DRVL paths, and thermal performance in 0°C to 70°C ambient environments.
Technical Context
The ADP3416JR-REEL implements adaptive nonoverlap timing: high-side turn-on is delayed until DRVL falls to ~10% VCC plus 20 ns, while low-side turn-on waits for SW node voltage to drop below 1 V. Its high-side driver operates from a floating BST–SW rail, supporting up to 26 V bootstrap voltage with internal 5 V logic-level input compatibility.
Both drivers deliver ≤40 ns rise/fall times into 3 nF loads at 7 V VCC, with sourcing/sinking output resistances of 2.0–4.0 Ω (high-side) and 2.0–4.0 Ω (low-side). The device uses internal PGND-referenced biasing for DRVL and bootstrap-referenced biasing for DRVH, enabling operation across 4.15–7.5 V VCC and –0.3–30 V BST ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.15 V to 7.5 V - supports standard 5 V and 7 V supply rails without external regulation |
| High-Side Sourcing RDS(ON) | 2.0 Ω (typ) at VBST–VSW = 7 V - enables fast turn-on of high-side N-MOSFETs with <40 ns rise time into 3 nF |
| Low-Side Sinking RDS(ON) | 1.0 Ω (typ) at VCC = 7 V - ensures rapid discharge of synchronous rectifier gate capacitance |
| Propagation Delay (DRVH) | 65–90 ns (tpdh), 25–35 ns (tpdl) - tightly matched timing critical for minimizing dead-time uncertainty |
| Overlap Protection Threshold | SW node monitored at 1 V threshold - guarantees Q1 fully off before Q2 turns on, independent of temperature/voltage drift |
| Package | 8-Lead SOIC (R-8) - industry-standard footprint compatible with automated PCB assembly and thermal relief design |
| Operating Temperature | 0°C to 70°C ambient - qualified for commercial-grade CPU VRM and point-of-load applications |
Pinout & Package
ADP3416JR-REEL is housed in an 8-lead narrow-body SOIC package (JEDEC MS-012AA, R-8 outline) with 1.27 mm lead pitch and exposed thermal pad not present. Pin 3 is NC; all other pins are electrically functional per datasheet specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BST (Pin 1) | Floating bootstrap supply rail | Provides gate drive voltage referenced to SW node; requires 100 nF–1 µF ceramic capacitor to sustain high-side conduction during switching cycles |
| IN (Pin 2) | TTL-compatible PWM input | Accepts 0.8 V / 2.3 V logic thresholds; single signal controls both DRVH (in-phase) and DRVL (180° out-of-phase) outputs |
| NC (Pin 3) | No connection | Unbonded die pad; must remain unconnected on PCB to avoid parasitic coupling or latch-up risk |
| VCC (Pin 4) | Main supply input | Powers low-side driver and logic; requires local 1 µF MLCC bypass to PGND for transient current support |
| DRVL (Pin 5) | Low-side MOSFET gate driver | Drives synchronous rectifier (Q2); output held low when disabled to prevent shoot-through |
| PGND (Pin 6) | Power ground reference | Must be connected directly to source of low-side MOSFET to minimize ground bounce affecting overlap protection |
| SW (Pin 7) | Switching node monitor | References high-side driver and triggers low-side enable only after voltage drops below 1 V - core of adaptive overlap protection |
| DRVH (Pin 8) | High-side MOSFET gate driver | Outputs bootstrapped gate drive for upper N-MOSFET (Q1); held low when disabled to ensure safe startup |
Key Features
| Feature | Design Value |
|---|---|
| All-in-one synchronous buck driver | Integrates matched high/low-side drivers, overlap logic, and bootstrap interface in single SOIC-8 - eliminates discrete timing components and layout complexity |
| Adaptive overlap protection | Monitors SW node voltage (not fixed delay) to guarantee Q1 OFF before Q2 ON - maintains shoot-through immunity across input voltage, temperature, and MOSFET gate charge variation |
| Single-PWM control architecture | Converts one TTL-level input into complementary, nonoverlapping DRVH/DRVL outputs - simplifies controller interface and reduces signal routing count |
| High-speed gate drive | ≤40 ns rise/fall into 3 nF load at 7 V - supports >1 MHz switching frequencies in compact VRMs without sacrificing efficiency |
| Robust bootstrap interface | Supports BST up to 30 V with –0.3 V to +8 V BST–SW rating - accommodates wide VIN ranges including 12 V and 19 V laptop adapters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2110SPBF | Higher voltage rating (600 V high-side), but requires separate logic and gate supplies; no integrated overlap protection | Suitable for high-voltage industrial half-bridge, not optimized for low-voltage CPU VRM timing precision | Select IR2110SPBF only when >100 V bus voltage or isolated level-shifting is required - ADP3416JR-REEL offers superior timing control for sub-24 V buck applications |
| LM5112MYX/NOPB | 3 A peak drive current, 12 V VCC max, no bootstrap circuit - designed for direct VCC-referenced high-side drive only | Requires external high-side level shifter; lacks SW-node monitoring for adaptive dead-time control | Choose LM5112MYX/NOPB for simpler, lower-cost 5–12 V systems where fixed dead-time suffices - ADP3416JR-REEL delivers tighter timing margin for high-efficiency VRMs |
Compared with IR2110SPBF and LM5112MYX/NOPB, the ADP3416JR-REEL uniquely integrates adaptive SW-sensing overlap protection and single-supply bootstrap operation in SOIC-8, making it the preferred choice for space-constrained, high-efficiency synchronous buck converters below 24 V input.

FAQ
What is the maximum allowable bootstrap voltage for the ADP3416JR-REEL?
The ADP3416JR-REEL supports a BST pin voltage up to +30 V absolute maximum, with BST-to-SW differential voltage limited to –0.3 V to +8 V. In practice, the bootstrap capacitor must be rated for at least 50 V to safely handle VIN + 5 V transients. This rating ensures reliable high-side gate drive in 12 V and 19 V adapter-powered systems where VIN can reach 24 V during surge events. The ADP3416JR-REEL's internal circuitry remains functional within these limits without derating.
Does the ADP3416JR-REEL require external components for overlap protection?
No, the ADP3416JR-REEL implements fully integrated adaptive overlap protection without external components. It monitors the SW pin voltage to delay low-side turn-on until the node falls below 1 V, and uses internal timing to delay high-side turn-on after low-side turn-off. This eliminates the need for external RC networks or comparators used in discrete solutions. The ADP3416JR-REEL's overlap circuit is self-calibrating across temperature and supply voltage, ensuring robust shoot-through prevention in all operating conditions.
Can the ADP3416JR-REEL drive MOSFETs with gate charges exceeding 50 nC?
Yes, the ADP3416JR-REEL can drive MOSFETs with gate charges above 50 nC when paired with appropriate external bootstrap capacitance. Its 2.0 Ω typical high-side sourcing resistance and 40 ns rise time into 3 nF indicate strong drive strength. For a 50 nC gate charge at 7 V, a minimum 100 nF bootstrap capacitor is recommended to limit droop to <200 mV. The ADP3416JR-REEL's robust output stage sustains this performance without thermal throttling in its specified 0°C to 70°C ambient range.
What is the purpose of the NC pin (Pin 3) on the ADP3416JR-REEL?
Pin 3 of the ADP3416JR-REEL is designated NC (No Connection) and contains no internal bond wire or circuit connection. It must remain unconnected on the PCB layout to prevent unintended coupling, noise injection, or potential latch-up. Unlike some "no-connect" pins that serve as thermal pads or test points, the ADP3416JR-REEL's Pin 3 is electrically isolated - leaving it floating is mandatory per Analog Devices' layout guidelines. This ensures signal integrity for adjacent pins IN and VCC in high-speed switching applications.
How does the ADP3416JR-REEL handle startup and initial bootstrap charging?
At startup, the ADP3416JR-REEL relies on the SW pin being near PGND to charge the external bootstrap capacitor through the Schottky diode. When IN is low and Q2 is off, SW sits at PGND, allowing VCC to charge CBST to ~VCC – VF(diode). Once the first PWM pulse occurs, DRVH pulls high, turning on Q1 and raising SW toward VIN; this lifts BST to VIN + VC(BST), sustaining gate drive. The ADP3416JR-REEL's internal logic ensures DRVL remains low during initial cycles to guarantee proper bootstrap initialization before full regulation begins.
