Texas Instruments TPS2830PWPR

Overview

TPS2830PWPR 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, supporting 4.5–15-V supply voltage, featuring adaptive dead-time control and internal Schottky bootstrap diode, and optimized for high-current single-phase DC/DC converters.

For engineers reviewing the TPS2830PWPR datasheet, TPS2830PWPR pinout, TPS2830PWPR application, or TPS2830PWPR equivalent, key selection criteria include bootstrap configuration flexibility (floating or ground-referenced), CROWBAR overvoltage protection response, SYNC-controlled synchronous/nonsynchronous mode, thermal performance in HTSSOP PowerPAD package, and compatibility with PWM controllers lacking integrated drivers.

Technical Context

The TPS2830PWPR implements dual-output gate driving with independent high-side (BOOT/HIGHDR/BOOTLO) and low-side (LOWDR/PGND) paths, where the high-side driver operates via floating bootstrap architecture using an internal Schottky diode and supports up to 30-V BOOT-to-PGND differential. Adaptive dead-time control is implemented through the DT terminal connected to the power FET junction, preventing shoot-through by enforcing nonoverlap timing between HIGHDR and LOWDR transitions.

Control logic includes ENABLE (global disable), SYNC (low-side enable/disable for synchronous/nonsynchronous operation), and CROWBAR (forced low-side turn-on during high-side fault). Input threshold voltages require ≥0.7×VCC for high-level recognition on ENABLE, SYNC, CROWBAR, IN, and DT terminals, ensuring robust noise immunity in noisy power-converter environments.

FAQ

What is the maximum allowable voltage between BOOT and PGND for the TPS2830PWPR?

The absolute maximum voltage between BOOT and PGND for the TPS2830PWPR is 30 V. This rating enables use in buck converters with input voltages up to 24 V while maintaining sufficient margin for ringing and overshoot. Exceeding this limit risks permanent damage to the internal high-side driver circuitry. Designers should ensure bootstrap capacitor selection and PCB layout minimize voltage spikes at the BOOT node.

How does the CROWBAR function protect the system when the high-side MOSFET fails shorted?

When the CROWBAR input is driven low-typically by an external overvoltage detection circuit-the TPS2830PWPR immediately forces LOWDR high and HIGHDR low, overriding all other control signals including IN and SYNC. This turns on the low-side MOSFET as a clamping device, shunting excess energy to ground and limiting output voltage rise. The function acts within nanoseconds, preventing damage to downstream loads such as FPGAs or sensors in systems like automotive ADAS cameras.

Can the TPS2830PWPR operate in nonsynchronous mode, and how is it configured?

Yes, the TPS2830PWPR supports nonsynchronous operation via the SYNC input. When SYNC is held low, the low-side driver (LOWDR) is disabled, allowing use of a freewheeling diode instead of a synchronous rectifier. This mode reduces complexity and cost in lower-efficiency or lower-current applications. The high-side driver remains fully functional, and the driver continues to provide adaptive dead-time control to prevent shoot-through during transitions.

What is the purpose of the DT (dead-time) pin, and how must it be connected?

The DT pin on the TPS2830PWPR senses the voltage at the drain-source junction of the power FETs (i.e., the node connecting high-side drain and low-side source). It must be connected directly to that node via a short, low-inductance trace. The internal adaptive circuit uses this signal to dynamically adjust the nonoverlap time between HIGHDR and LOWDR transitions, eliminating shoot-through current without requiring external timing components or fixed dead-time settings.

Is the TPS2830PWPR pin-compatible with other devices in the TPS283x family, and which ones share the same PWP package?

Yes, the TPS2830PWPR is pin-compatible with TPS2831PWPR (inverting input), TPS2834PWPR (TTL input), and TPS2835PWPR (TTL + inverting) in the same HTSSOP-14 PowerPAD (PWP) package. All share identical pin assignments, thermal pad layout, and footprint. This allows design reuse across variants-e.g., swapping TPS2830PWPR for TPS2834PWPR requires only logic-level compatibility verification, not PCB revision.
