Product details
Overview
TPS2830D from Texas Instruments is a noninverting high-side/low-side MOSFET driver for synchronous-buck power stages, delivering 2.4-A peak output current, supporting 4.5–15-V supply voltage, featuring adaptive dead-time control and internal Schottky bootstrap diode, and used in high-current single-phase DC/DC converters.
For engineers reviewing the TPS2830D datasheet, TPS2830D pinout, TPS2830D application, or TPS2830D equivalent, key selection criteria include bootstrap-capable high-side drive, CROWBAR overvoltage protection, SYNC-controlled synchronous/nonsynchronous mode, and SOIC-14 thermal performance across −40°C to 125°C junction range.
Technical Context
The TPS2830D integrates dual N-channel gate drivers with adaptive dead-time logic that monitors the BOOTLO node (drain of high-side FET) to prevent shoot-through during switching transitions. Its noninverting IN input directly accepts PWM signals from external controllers like TL5001A.
It implements three critical protection/control functions: ENABLE disables both outputs when low; SYNC forces nonsynchronous operation by disabling LOWDR when low; CROWBAR overrides normal logic to turn on LOWDR and disable HIGHDR during overvoltage events, clamping the output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 15 V - supports wide-input industrial and telecom DC/DC supplies without external regulation |
| Peak Output Current | 2.4 A typical - drives large gate capacitances of low-RDS(on) N-channel MOSFETs in high-current buck stages |
| Rise/Fall Time | ≤50 ns max (VCC = 6.5 V, CL = 3.3 nF) - enables high-frequency switching up to 1 MHz with minimal switching loss |
| Propagation Delay | ≤100 ns max (VBOOT = 6.5 V) - ensures tight timing alignment between high-side and low-side gate drive edges |
| Operating Temperature | −40°C to 125°C virtual junction - validated for under-hood automotive and industrial power supply environments |
| Bootstrap Voltage Limit | 30 V max (BOOT to PGND) - accommodates high-voltage buck converters with 24-V or 48-V input rails |
| Quiescent Supply Current | 3 mA typical - minimizes no-load power loss in always-on power management systems |
Pinout & Package
TPS2830D is housed in a 14-pin SOIC (D) package with 1.27-mm pitch, 8.75 mm × 3.91 mm body, and 1.75 mm max height, optimized for automated assembly and thermal dissipation via exposed leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - ENABLE | Digital input | Global enable/disable: pulls both drivers low when logic low; required for safe startup/shutdown sequencing |
| 2 - IN | Noninverting input | Accepts PWM signal directly; output follows input polarity - distinguishes TPS2830D from inverting TPS2831D |
| 3 - CROWBAR | Overvoltage override input | Active-low fault response: forces LOWDR on and HIGHDR off to clamp output during high-side FET short |
| 4, 9, 13 - NC | No internal connection | Unbonded pins; must be left floating or grounded per layout best practices - no electrical function |
| 5 - SYNC | Synchronous rectifier control | High = synchronous mode (LOWDR active); Low = nonsynchronous mode (LOWDR disabled) |
| 6 - DT | Dead-time sense input | Connected to BOOTLO node; enables adaptive dead-time generation to eliminate shoot-through at all loads |
| 7 - PGND | Power ground | High-current return path for gate drive currents; must be routed separately from signal ground to avoid noise coupling |
| 8 - VCC | Driver supply input | Primary power rail; requires local 1-µF ceramic bypass capacitor to PGND for stable high-frequency operation |
| 10 - LOWDR | Low-side gate driver output | Sinks/sourced 2.4-A peak into low-side N-MOSFET gate; designed for direct connection to source-referenced FETs |
| 11 - BOOTLO | Bootstrap return node | Connects to high-side/low-side FET drain node; provides reference for floating high-side driver and DT sensing |
| 12 - HIGHDR | High-side gate driver output | Drives high-side N-MOSFET gate referenced to BOOT; capable of 2.4-A peak sink/source with internal Schottky bootstrap diode |
| 14 - BOOT | Bootstrap supply terminal | Connects to bootstrap capacitor (0.1–1 µF) between BOOT and BOOTLO; develops floating voltage for high-side driver |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Dead-Time Control | Monitors BOOTLO voltage to dynamically adjust turn-on delays, eliminating shoot-through without fixed timing components |
| Integrated Schottky Bootstrap Diode | Reduces external component count and improves bootstrap recharge efficiency vs discrete diode solutions |
| CROWBAR Overvoltage Protection | Hardware-level fault response that overrides logic to clamp output during high-side FET failure - no software or controller dependency |
| SYNC-Controlled Operation Mode | Single-pin selection between synchronous rectification (high efficiency) and nonsynchronous (diode-based) topologies |
| Thermally Enhanced SOIC Package | SOIC-14 with optimized leadframe thermal path supports >1 W continuous dissipation at 70°C ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MOSFET driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2831D | Inverting input logic vs TPS2830D's noninverting input; identical pinout, specs, and features otherwise | Requires inverted PWM signal from controller; unsuitable where controller outputs noninverted gate drive | Select TPS2831D only when controller output polarity matches its inverting input requirement |
| TPS2834D | TTL-compatible input thresholds (vs CMOS on TPS2830D); same pinout and driver specs | Accepts lower-voltage logic interfaces (e.g., 3.3-V microcontroller GPIO) without level-shifting | Choose TPS2834D for direct interface with TTL/3.3-V logic; TPS2830D requires ≥0.7×VCC input high threshold |
Compared with TPS2831D and TPS2834D, the TPS2830D provides noninverting CMOS-compatible control with industry-standard SOIC-14 footprint, making it optimal for legacy PWM controllers and designs prioritizing signal polarity fidelity over logic-level flexibility.

FAQ
What is the input logic polarity of the TPS2830D?
The TPS2830D features a noninverting input: when the IN pin is driven high, HIGHDR goes high and LOWDR goes low (subject to ENABLE and SYNC states). This distinguishes it from the inverting TPS2831D and ensures direct compatibility with standard PWM controllers such as TL5001A without signal inversion.
Does the TPS2830D require an external bootstrap diode?
No - the TPS2830D integrates a Schottky bootstrap diode internally, connecting VCC to BOOT during the low-side conduction phase. This eliminates the need for an external diode, reduces board area, and improves bootstrap recharge efficiency compared to discrete solutions.
How does the CROWBAR function protect the system when used with the TPS2830D?
When the CROWBAR pin is pulled low (e.g., by an external OVP comparator), the TPS2830D immediately forces LOWDR high and HIGHDR low - overriding IN, ENABLE, and SYNC. This turns on the low-side FET as a clamp, limiting output voltage rise during high-side FET short-circuit faults, protecting downstream 3.3-V or 5-V circuitry.
What is the maximum allowable bootstrap voltage for the TPS2830D?
The TPS2830D supports a maximum voltage of 30 V between BOOT and PGND. This rating allows use in higher-input buck converters (e.g., 24-V or 48-V input rails) while maintaining safe operation of the internal high-side driver and bootstrap capacitor network.
Can the TPS2830D operate in nonsynchronous mode, and how is it configured?
Yes - the TPS2830D operates in nonsynchronous mode when the SYNC pin is held low. In this state, the low-side driver (LOWDR) is disabled, allowing use with an external freewheeling diode instead of a synchronous rectifier, simplifying design for lower-cost or lower-power applications.
