Product details
Overview
TPS2830DR from Texas Instruments is a noninverting high-side/low-side MOSFET driver IC for synchronous-buck power stages, delivering 2.4-A peak output current, operating from 4.5-V to 15-V supply, featuring adaptive dead-time control, internal Schottky bootstrap diode, and CROWBAR over-voltage protection - used in high-current single-phase DC/DC converters.
For engineers reviewing the TPS2830DR datasheet, TPS2830DR pinout, TPS2830DR application, or TPS2830DR equivalent, key selection criteria include bootstrap-configurable high-side drive, 50-ns max rise/fall times with 3.3-nF load, −40°C to 125°C virtual junction temperature range, and SOIC-14 package compatibility with thermal PowerPAD variants.
Technical Context
The TPS2830DR implements adaptive dead-time control by monitoring the DT terminal connected to the high-side/low-side FET junction, preventing shoot-through during switching transitions. Its noninverting input (IN) directly accepts PWM signals from external controllers like TL5001A, while ENABLE, SYNC, and CROWBAR terminals provide system-level control of driver enablement, synchronous/nonsynchronous mode selection, and fault-triggered low-side clamping.
It supports both floating bootstrap and ground-reference high-side configurations, with BOOT–BOOTLO voltage up to 30 V and integrated Schottky diode enabling efficient bootstrap capacitor charging. The driver's bipolar+MOSFET output stage delivers 2.4-A peak sink/source into capacitive gate loads, optimized for low RDS(on) N-channel power FETs in high-frequency buck regulators.
Key Specifications

Pinout & Package
TPS2830DR is packaged in a 14-pin SOIC (D) with 1.27-mm pitch and 1.75-mm max height, optimized for surface-mount assembly and thermal performance via exposed pad grounding in PowerPAD variants (though TPS2830DR specifically denotes the SOIC tape-and-reel version).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENABLE (Pin 1) | Digital enable input | Drives both outputs low when logic-low; required for safe startup/shutdown sequencing |
| IN (Pin 2) | Noninverting control input | Directly mirrors PWM signal polarity - matches standard controller outputs without inversion logic |
| CROWBAR (Pin 3) | OVP override input | Forces low-side FET on and disables high-side upon external overvoltage detection - protects downstream loads |
| NC (Pins 4, 9, 13) | No internal connection | Unused pins; must be left unconnected or tied to GND per layout best practices |
| SYNC (Pin 5) | Synchronous rectifier control | High = enables low-side drive (synchronous mode); Low = disables low-side (nonsynchronous diode emulation) |
| DT (Pin 6) | Dead-time sensing node | Connected to high/low-FET junction to dynamically adjust turn-on delays and eliminate shoot-through |
| PGND (Pin 7) | Power ground return | Low-impedance path for high-current gate drive return - must be routed separately from signal ground |
| VCC (Pin 8) | Driver supply input | Requires local 1-µF ceramic bypass capacitor to PGND to stabilize gate drive rail during transient loading |
| BOOT (Pin 14) | Bootstrap capacitor top node | Supplies floating high-side gate voltage; connects to ceramic bootstrap cap (0.1–1 µF) and internal Schottky diode anode |
| BOOTLO (Pin 11) | Bootstrap capacitor bottom node | Connects to high/low-FET source junction - forms bootstrap voltage reference for high-side driver |
| HIGHDR (Pin 12) | High-side gate driver output | Delivers 2.4-A peak current to high-side N-MOSFET gate; rated for 30-V max BOOT-to-PGND swing |
| LOWDR (Pin 10) | Low-side gate driver output | Sinks/sources 3.5-A peak into low-side FET gate; operates referenced to PGND for simplified layout |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Dead-Time Control | Eliminates need for fixed external dead-time circuits by sensing FET junction voltage and automatically delaying complementary FET turn-on |
| Integrated Schottky Bootstrap Diode | Reduces external component count and improves bootstrap efficiency vs. discrete diode solutions, especially at high duty cycles |
| CROWBAR Over-Voltage Protection | Provides hardware-level fail-safe response to high-side FET short-circuit faults by forcing low-side conduction to clamp output voltage |
| SYNC-Controlled Synchronous Mode | Enables seamless transition between synchronous rectification (high efficiency) and nonsynchronous operation (diode emulation) via single logic pin |
| Thermally Enhanced SOIC Packaging | SOIC-14 with optimized thermal resistance supports continuous 2.4-A peak drive without derating in compact 1-in² PCB footprints |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2830D | Same silicon, SOIC-14 tube-packaged variant (no 'R' suffix); identical electrical specs and pinout | No tape-and-reel packaging - suited for prototyping or low-volume manual assembly | Select TPS2830D for bench validation; TPS2830DR for automated SMT production requiring 2000-piece reels |
| TPS2834PWPR | TTL-input, noninverting variant in HTSSOP-14 PowerPAD package; same features but different logic threshold (TTL vs CMOS) | Higher thermal performance (2.07 °C/W junction-case) and smaller footprint - preferred for space-constrained designs | Choose TPS2834PWPR when board area or thermal headroom is limited; verify controller output logic family compatibility |

FAQ
What is the input logic type supported by the TPS2830DR?
The TPS2830DR features a CMOS-compatible noninverting input (IN pin), with high-level input voltage ≥0.7×VCC and low-level ≤1 V across the 4.5–15-V supply range. This allows direct interface with standard PWM controllers such as TL5001A, UC384x series, or microcontroller GPIOs without level-shifting circuitry. The TPS2830DR does not accept TTL logic thresholds - use TPS2834PWPR if TTL input is required.
Does the TPS2830DR include an internal bootstrap diode?
Yes, the TPS2830DR integrates a Schottky bootstrap diode connected between VCC and BOOT pins. This eliminates the need for an external diode in bootstrap gate drive circuits, reducing BOM count and improving charge efficiency - especially beneficial in high-duty-cycle applications. The diode supports up to 30 V reverse voltage and is rated for continuous bootstrap capacitor charging current.
How does the CROWBAR function protect the system in the TPS2830DR?
The CROWBAR function in the TPS2830DR overrides normal gate drive logic when the CROWBAR pin is driven low, immediately turning on the low-side FET and disabling the high-side FET. This clamps the output voltage during high-side MOSFET short-circuit faults - preventing overvoltage damage to downstream loads. It operates independently of IN, ENABLE, and SYNC states, providing hardware-level fail-safe response without software intervention.
What package type is used for the TPS2830DR?
The TPS2830DR uses the SOIC-14 (D) package with 1.27-mm lead pitch and 1.75-mm maximum height. It is supplied in tape-and-reel format (2000 units per reel), optimized for automated SMT placement. Unlike the PWP (HTSSOP) variants, the SOIC package offers broader reflow compatibility and easier manual rework, though with higher thermal resistance than PowerPAD-equipped versions.
Can the TPS2830DR drive both high-side and low-side N-channel MOSFETs?
Yes, the TPS2830DR is explicitly designed to drive two N-channel MOSFETs in a synchronous buck topology: the high-side driver operates in floating bootstrap mode (via BOOT/BOOTLO), while the low-side driver is ground-referenced (LOWDR to PGND). Both channels deliver 2.4-A peak current and support fast switching (≤50 ns rise/fall), enabling efficient replacement of P-channel high-side solutions with lower RDS(on) N-channel devices.
