Product details
Overview
TPS2830PWP 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, internal Schottky bootstrap diode, and CROWBAR overvoltage protection-designed for high-current single-phase DC/DC converters in telecom and industrial power supplies.
For engineers reviewing the TPS2830PWP datasheet, TPS2830PWP pinout, TPS2830PWP application, or TPS2830PWP 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 TSSOP PowerPAD thermal performance for high-density power stage layouts.
Technical Context
The TPS2830PWP implements dual-output gate driving with independent high-side (BOOT/BOOTLO/HIGHDR) and low-side (LOWDR) paths, where the high-side driver operates either as floating bootstrap or ground-referenced via configurable DT terminal connection. Adaptive dead-time logic monitors BOOTLO node voltage to prevent shoot-through during switching transitions.
Control architecture integrates ENABLE (global disable), SYNC (synchronous/nonsynchronous mode selection), and CROWBAR (OVP-triggered low-side override), all requiring ≥0.7×VCC high-level input. Input is noninverting, distinguishing it from the inverting TPS2831 variant-both share identical package, thermal rating, and driver strength specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 15 V - supports wide-input buck regulators powered from 5 V, 12 V, or intermediate rails without external regulation. |
| Peak Output Current | 2.4 A source/sink - drives large gate capacitances of low-RDS(on) N-channel MOSFETs in high-current (>3 A) power stages. |
| Rise/Fall Time | ≤50 ns (HIGHDR), ≤30 ns (LOWDR) at 3.3-nF load - enables >1-MHz switching frequencies with minimal gate drive loss. |
| Propagation Delay | ≤100 ns (HIGHDR), ≤70 ns (LOWDR) - ensures tight timing alignment between high- and low-side FETs for stable PWM operation. |
| Operating Temperature | −40°C to 125°C virtual junction - validated for under-hood automotive, industrial, and telecom environments with localized heating. |
| Bootstrap Voltage Limit | Max 30 V BOOT-to-PGND - accommodates high-voltage buck applications up to 28 V input with margin. |
| Quiescent Supply Current | 3 mA typical at 12 V - minimizes no-load power loss in always-on or standby power management systems. |
Pinout & Package
TPS2830PWP is housed in a thermally enhanced HTSSOP-14 (PWP) package with exposed PowerPAD for improved heat dissipation. Package dimensions: 4.4 mm × 5.0 mm × 1.2 mm, 0.65-mm pitch, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ENABLE | Global enable input | Drives both drivers OFF when low; requires ≥0.7×VCC to activate - used for power sequencing or fault shutdown. |
| 2 IN | Noninverting input signal | Directly controls HIGHDR/LOWDR states without inversion - matches standard PWM controller outputs (e.g., TL5001A). |
| 3 CROWBAR | OVP override input | Forces LOWDR ON and HIGHDR OFF when pulled low - clamps output during high-side FET short-circuit faults. |
| 4, 9, 13 NC | No internal connection | Unbonded pins; must remain unconnected per TI design - no routing or grounding required. |
| 5 SYNC | Synchronous rectifier control | Disables LOWDR when low (nonsynchronous mode); enables full synchronous operation when high - selectable per system efficiency needs. |
| 6 DT | Dead-time sensing node | Connected to high-/low-side FET junction; enables adaptive dead-time to eliminate shoot-through without fixed delay programming. |
| 7 PGND | Power ground reference | Low-impedance return path for gate drive currents - must be tied directly to FET source/power ground plane, separate from signal ground. |
| 8 VCC | Main supply input | Supplies both drivers; requires local 1-µF ceramic bypass capacitor to PGND - decouples high di/dt transients during switching. |
| 10 LOWDR | Low-side gate driver output | Drives N-channel MOSFET source - rated for 2.4-A peak sink/source into capacitive loads up to 3.3 nF. |
| 11 BOOTLO | Bootstrap return node | Connects to high-/low-side FET junction - carries high-frequency gate drive return current; must be routed with minimal inductance. |
| 12 HIGHDR | High-side gate driver output | Drives N-channel MOSFET gate referenced to BOOT - delivers 2.4-A peak current with internal Schottky bootstrap diode. |
| 14 BOOT | Bootstrap supply terminal | Accepts floating voltage from external 0.1–1 µF ceramic capacitor - develops gate drive voltage above BOOTLO for high-side FET turn-on. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive Dead-Time Control | Monitors BOOTLO voltage to dynamically adjust turn-on delays - eliminates need for external RC timing networks and prevents shoot-through across varying load/temperature conditions. |
| Integrated Schottky Bootstrap Diode | Eliminates external bootstrap diode - reduces BOM count, PCB area, and forward voltage drop, improving high-side drive efficiency and thermal margin. |
| CROWBAR Overvoltage Protection | Hardware-level OVP response that overrides IN/SYNC logic to clamp output - protects downstream loads during catastrophic high-side FET failure without software intervention. |
| TSSOP PowerPAD Thermal Package | 2.07 °C/W junction-to-case thermal resistance - enables >2 W continuous power dissipation in compact layouts without heatsinks or forced airflow. |
| SYNC-Controlled Mode Selection | Single-pin configuration of synchronous vs. nonsynchronous operation - allows reuse of same driver IC across multiple converter topologies without layout changes. |

FAQ
What is the function of the DT pin on the TPS2830PWP?
The DT (Dead-Time) pin on the TPS2830PWP connects to the junction of the high-side and low-side power MOSFETs. It enables adaptive dead-time control by monitoring the voltage at that node, preventing simultaneous conduction (shoot-through) by ensuring the low-side FET is fully off before the high-side turns on-and vice versa. This eliminates fixed-delay timing components and improves efficiency across load and temperature variations. The TPS2830PWP uses this signal internally; no external circuitry is required.
Does the TPS2830PWP include an internal bootstrap diode?
Yes, the TPS2830PWP integrates a Schottky bootstrap diode internally. This eliminates the need for an external discrete diode in bootstrap-based high-side configurations, reducing bill-of-materials count, PCB area, and forward voltage drop-thereby improving gate drive efficiency and thermal performance. The diode is rated for continuous operation with BOOT-to-PGND voltages up to 30 V, supporting high-input-voltage buck applications.
How does the CROWBAR feature protect the system when using the TPS2830PWP?
The CROWBAR feature on the TPS2830PWP provides hardware-level overvoltage protection: when the CROWBAR pin is driven low (e.g., by an external OVP comparator), the device immediately forces the LOWDR output high and disables HIGHDR-regardless of IN, ENABLE, or SYNC states. This clamps the output to ground, protecting downstream loads from overvoltage caused by a shorted high-side MOSFET. The TPS2830PWP's CROWBAR response is deterministic and faster than software-based protection schemes.
Can the TPS2830PWP drive both high-side and low-side N-channel MOSFETs in a synchronous buck converter?
Yes, the TPS2830PWP is explicitly designed to drive both high-side and low-side N-channel MOSFETs in synchronous-buck topologies. Its high-side driver operates in floating bootstrap mode (via BOOT/BOOTLO) or ground-referenced mode, while the low-side driver is ground-referenced. Both outputs deliver 2.4-A peak source/sink current into 3.3-nF loads, with ≤50-ns rise/fall times-enabling efficient, high-frequency operation with modern low-RDS(on) MOSFETs.
What is the maximum allowable voltage between BOOT and PGND for the TPS2830PWP?
The absolute maximum voltage between BOOT and PGND for the TPS2830PWP is 30 V, as specified in the Absolute Maximum Ratings table. This rating allows safe operation in buck converters with input voltages up to 28 V (with 2-V margin), including transient conditions. Exceeding 30 V risks permanent damage to the internal high-side driver circuitry. Designers must ensure the bootstrap capacitor and associated layout maintain this limit under all operating and fault conditions.
