Product details
Overview
TPS63030DSKT from Texas Instruments is an adjustable-output, high-efficiency single-inductor buck-boost DC/DC converter optimized for battery-powered systems. It operates from 1.8 V to 5.5 V input, delivers up to 600 mA output at 2.5 V (single Li-ion), achieves 96% peak efficiency, and features automatic buck/boost mode transition - used in portable medical devices, IP cameras, and handheld data terminals requiring stable rail generation across wide battery discharge curves.
For engineers reviewing the TPS63030DSKT datasheet, TPS63030DSKT pinout, TPS63030DSKT application, or TPS63030DSKT equivalent, key selection criteria include its 1.2–5.5 V programmable output range, 2.5-mm × 2.5-mm VSON-10 package with exposed thermal pad, power-save mode enabling <35 μA quiescent current, and integrated overtemperature protection with 140°C trip point.
Technical Context
The TPS63030DSKT implements a fixed-frequency average-current-mode control architecture with dual-stage regulation: a fast inner current loop stabilizes inductor current, while an outer voltage loop maintains output accuracy via 500 mV FB reference. Input and output voltage feed-forward enables rapid transient response during battery voltage sag or load steps.
Its 4-switch synchronous topology uses two dedicated ground paths - GND for logic/reference and PGND for power switching - minimizing ground shift errors. The device automatically selects buck or boost operation based on VIN-to-VOUT ratio, maintaining high efficiency near the crossover region by minimizing RMS switch/inductor current and eliminating simultaneous switching of all four MOSFETs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 5.5 V - supports full discharge of single-cell Li-ion (2.5 V min) and multi-cell alkaline/NiMH sources without external LDO pre-regulation. |
| Output Voltage Range | 1.2 V to 5.5 V - set externally via resistor divider on FB pin; enables flexible rail generation for mixed-voltage SoCs and sensors. |
| Max Output Current | 600 mA at 2.5 V (VIN = 2.4 V) - sufficient for ARM Cortex-M7 microcontrollers with peripherals active in portable instrumentation. |
| Switching Frequency | 2.4 MHz typical - allows use of compact 1.5 µH chip inductors and reduces output ripple without increasing EMI filtering complexity. |
| Quiescent Current | 35 µA typical - extends battery life in always-on monitoring modes (e.g., glucose meters in standby). |
| Efficiency Peak | 96% - achieved at mid-load (200–400 mA) with 3.6 V input → 3.3 V output, minimizing thermal stress in sealed enclosures. |
| Thermal Resistance | RθJA = 60.7 °C/W - requires minimal PCB copper area for thermal relief in 2.5-mm × 2.5-mm footprint applications. |
Pinout & Package
TPS63030DSKT is housed in a 2.5-mm × 2.5-mm, 10-pin VSON package (DSK) with an exposed thermal pad connected to PGND for enhanced heat dissipation in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Power output | Regulated buck-boost output node; connects directly to load or output capacitor bank. |
| VIN | Main power input | Supplies high-side switches; must be decoupled with ≥4.7 µF ceramic capacitor near pin. |
| VINA | Control-stage supply | Provides clean bias for internal regulators; requires 0.1 µF bypass to GND for noise immunity. |
| EN | Enable control | Active-high logic input; pulls device into shutdown (<0.9 µA ISHDN) when low, disconnecting load from input. |
| PS/SYNC | Mode control | Low = power-save enabled; high = forced PWM; external clock input synchronizes switching to system timing source. |
| FB | Feedback input | Monitors output via external resistor divider; 500 mV reference sets VOUT = 500 mV × (1 + R1/R2). |
| GND | Logic ground | Reference for EN, PS/SYNC, FB; must connect to PGND at single point near IC to avoid noise coupling. |
| PGND | Power ground | Return path for high-current switches and inductors; ties to exposed thermal pad for thermal conduction. |
| L1, L2 | Inductor connections | Connect opposite ends of single 1.5 µH inductor; polarity critical for proper buck-boost operation. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck/boost transition | Seamlessly shifts operating mode as VIN crosses VOUT, eliminating output glitches and manual mode selection in battery-powered systems. |
| Load disconnect during shutdown | Isolates output from input when EN = low, preventing battery drain through downstream circuitry in sleep states. |
| Integrated overtemperature protection | Shuts down at 140°C with 20°C hysteresis, protecting against thermal runaway in enclosed medical or industrial housings. |
| Separate GND and PGND pins | Prevents control-loop instability caused by high di/dt ground bounce, ensuring stable regulation under dynamic load conditions. |
| Soft-start with current limiting | Ramps average inductor current from zero to 1 A nominal, suppressing inrush current and output overshoot during cold start. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63031DSKT | Fixed 3.3 V output; FB pin internally tied to VOUT; identical package, pinout, and efficiency profile. | No external resistor divider required; simplified layout for fixed-rail systems but lacks output flexibility. | Select TPS63031DSKT when 3.3 V is the sole required output and board space is constrained. |
| MAX77827BEWL+T | Higher 1.2 A switch current limit; 2.2 MHz switching; integrated input OVP; different 12-pin WLP package. | Better suited for higher-current loads (>600 mA); requires PCB redesign due to non-pin-compatible footprint and different thermal pad layout. | Choose MAX77827BEWL+T only if sustained >700 mA output or input overvoltage protection is mandatory. |
Compared with TPS63030DSKT, TPS63031DSKT offers identical performance in a fixed-output configuration with zero external components, while MAX77827BEWL+T provides higher current capability and protection features at the cost of layout compatibility and increased BOM complexity.

FAQ
What output voltage range does the TPS63030DSKT support?
The TPS63030DSKT supports an adjustable output voltage range of 1.2 V to 5.5 V, set externally using a resistor divider connected to the FB pin. Its internal 500 mV feedback reference enables precise regulation, and the device maintains stability across this full range when paired with appropriate output capacitance and inductor selection per TI's design guidelines.
How does the TPS63030DSKT handle transitions between buck and boost modes?
The TPS63030DSKT automatically transitions between buck and boost modes based on the instantaneous relationship between VIN and VOUT, using an average-current-mode controller with voltage feed-forward. This ensures glitch-free regulation without manual intervention or external mode control, maintaining >90% efficiency even when VIN ≈ VOUT - a critical advantage for battery-powered systems undergoing voltage sag.
What is the purpose of the separate GND and PGND pins on the TPS63030DSKT?
The TPS63030DSKT uses separate GND (logic ground) and PGND (power ground) pins to isolate sensitive control circuitry from high-di/dt switching currents. GND serves as the reference for EN, PS/SYNC, and FB signals, while PGND carries inductor and switch return currents. Connecting them at a single point near the IC prevents ground bounce from corrupting regulation accuracy and ensures stable operation under dynamic load conditions.
Can the TPS63030DSKT operate with a single-cell Li-ion battery?
Yes, the TPS63030DSKT is explicitly designed for single-cell Li-ion and Li-polymer batteries, supporting input voltages from 1.8 V to 5.5 V. It delivers up to 600 mA at 2.5 V output when VIN drops to 2.4 V, enabling full utilization of the battery's discharge curve down to 2.5 V - ideal for portable medical and consumer devices where runtime extension is critical.
What thermal protection features does the TPS63030DSKT include?
The TPS63030DSKT incorporates integrated overtemperature protection that disables switching when the junction temperature exceeds 140°C, with 20°C hysteresis to prevent oscillation. This feature, combined with its low RθJA (60.7 °C/W) and exposed thermal pad tied to PGND, ensures reliable operation in sealed enclosures and high-ambient environments common in industrial and medical portable equipment.
