Product details
Overview
TPS63030DSKR from Texas Instruments is an adjustable-output, high-efficiency single-inductor buck-boost DC/DC converter IC designed for battery-powered systems. It operates from 1.8 V to 5.5 V input, delivers up to 600 mA output current at 2.5 V, achieves up to 96% efficiency, and features automatic buck/boost mode transition-used in portable medical devices requiring stable 3.3 V rail from declining Li-ion cells.
For engineers reviewing the TPS63030DSKR datasheet, TPS63030DSKR pinout, TPS63030DSKR application, or TPS63030DSKR equivalent, key selection considerations include its 10-pin VSON (DSK) package, 500 mV feedback reference, 2.4 MHz fixed switching frequency, power-save mode enable via PS/SYNC pin, and integrated 1-A synchronous switches with thermal shutdown.
Technical Context
The TPS63030DSKR implements average-current-mode control with input/output voltage feed-forward for fast transient response. Its four-NMOS switch topology enables seamless transition between buck and boost operation while maintaining high efficiency near VIN ≈ VOUT by minimizing RMS inductor current and conduction losses.
It integrates undervoltage lockout (1.5 V threshold on VINA), overtemperature protection (140 °C trip with 20 °C hysteresis), soft-start with controlled current ramp-up, and load disconnect during shutdown-ensuring safe start-up, robust fault handling, and low quiescent current (<35 μA typical) in battery-critical applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion (2.5–4.2 V), two/three-cell alkaline/NiMH (2.4–4.5 V) without external regulators |
| Output Voltage Range | 1.2 V to 5.5 V (adjustable) - set via external resistor divider; FB pin reference = 500 mV ±1% |
| Max Output Current | 600 mA at 2.5 V (VIN ≥ 2.4 V) - sufficient for MCU + sensor + BLE radio subsystems in portable diagnostics |
| Switching Frequency | 2.4 MHz typical - enables use of compact 1.5 µH inductors and small ceramic capacitors (e.g., 10 µF ×2 output) |
| Efficiency | Up to 96% - achieved via synchronous rectification and optimized gate drive, critical for extending battery runtime |
| Quiescent Current | 35 μA typical - maintains ultra-low standby power in always-on health monitoring modes |
| Thermal Protection | 140 °C shutdown with 20 °C hysteresis - prevents thermal runaway during sustained high-load or poor PCB heatsinking |
Pinout & Package
TPS63030DSKR is housed in a thermally enhanced 10-pin VSON package (DSK), 2.5 mm × 2.5 mm, with exposed thermal pad connected to PGND. The package supports tape-and-reel delivery (R suffix) for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Regulated buck-boost output; connects directly to load and output capacitor bank |
| L1 (Pin 4) | Inductor connection | High-side switch node for first inductor leg; requires low-ESR path to L1 |
| L2 (Pin 2) | Inductor connection | Low-side switch node for second inductor leg; ties to same inductor as L1 in single-inductor configuration |
| PGND (Pin 3) | Power ground | Return path for high-current switch nodes (L1/L2/VOUT); must be isolated from signal GND and joined at single point near GND pin |
| VIN (Pin 5) | Power stage supply | Input supply for high-current switches; decoupled with ≥4.7 µF ceramic capacitor close to pin |
| VINA (Pin 8) | Control stage supply | Supply for internal logic and regulation circuitry; bypassed with 0.1 µF ceramic capacitor |
| EN (Pin 6) | Enable control | Active-high digital enable; pulls device into full shutdown (≤0.9 µA ISHDN) when low |
| PS/SYNC (Pin 7) | Mode control | Low = power-save enabled; high = forced PWM; external clock input for synchronization |
| FB (Pin 10) | Feedback input | Senses output voltage via resistor divider; 500 mV reference sets VOUT = 500 mV × (1 + R1/R2) |
| GND (Pin 9) | Signal ground | Reference for all control circuits (FB, EN, PS/SYNC); must connect to PGND at single point near this pin |
Key Features
| Feature | Design Value |
|---|---|
| Single-inductor buck-boost topology | Eliminates need for separate buck and boost converters-reduces BOM count, board area, and design complexity in space-constrained portable devices |
| Automatic mode transition | Seamlessly shifts between step-down and step-up operation as input voltage crosses output voltage-ensures uninterrupted 3.3 V supply during Li-ion discharge from 4.2 V to 2.5 V |
| Integrated 1-A synchronous switches | Combines high- and low-side NMOS with <200 mΩ RDS(on) each-enables high efficiency without external MOSFETs or gate drivers |
| Load disconnect during shutdown | Prevents battery drain through output load when disabled-critical for long-term storage of handheld diagnostic tools |
| Power-save mode | Reduces switching activity at light loads to maintain >85% efficiency down to 1 mA output-extends runtime in intermittent-sensing applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63031DSKR | Fixed 3.3 V output; no external feedback divider required; identical pinout and package | Eliminates two resistors and layout area-preferred for cost-sensitive, fixed-rail designs where 3.3 V suffices | Select TPS63031DSKR if output voltage is fixed at 3.3 V and board space is constrained; otherwise retain TPS63030DSKR for flexibility. |
| MP2155GQ-Z | 2.5 V to 5.5 V input; 0.6 V to 5 V adjustable output; 2.2 MHz switching; 1.2 A switches; QFN-10 (3×3 mm) | Larger footprint (3 mm vs 2.5 mm), higher max current, but lower max efficiency (94% vs 96%) and no integrated load disconnect | Choose MP2155GQ-Z only if >600 mA output or wider input range (down to 2.5 V) is mandatory; TPS63030DSKR offers superior thermal performance and smaller size. |
Compared with TPS63031DSKR, the TPS63030DSKR provides output voltage flexibility at minor BOM cost; versus MP2155GQ-Z, it delivers better efficiency in compact 2.5-mm footprint with guaranteed load isolation-making it optimal for space- and runtime-critical portable medical and industrial edge devices.

FAQ
What is the recommended inductor value for TPS63030DSKR in a 3.3 V output design?
The recommended inductor for TPS63030DSKR at 3.3 V output is 1.5 µH, such as Coilcraft LPS3015-1R5. This value balances ripple current, transient response, and efficiency-supporting up to 600 mA output while maintaining stability across input voltages from 1.8 V to 5.5 V. TI specifies this value in the official TPS63030DSKR application schematic and design guidelines.
Does TPS63030DSKR require external compensation components?
No, TPS63030DSKR uses internal compensation and does not require external compensation components. Its average-current-mode control architecture is factory-tuned for stability with standard 1.5 µH inductors and 10 µF ceramic output capacitors. Adding external compensation may destabilize the loop and is neither recommended nor supported in the TPS63030DSKR datasheet.
Can TPS63030DSKR operate with input voltage below 1.8 V?
No, TPS63030DSKR has a minimum recommended input voltage of 1.8 V and a startup threshold of 1.6 V (typical). Operation below 1.8 V violates recommended conditions and risks unstable regulation or failure to start. For sub-1.8 V inputs, consider TI's TPS63802 or alternative ultra-low-VIN buck-boost converters-not the TPS63030DSKR.
How is load disconnect implemented in TPS63030DSKR during shutdown?
TPS63030DSKR implements true load disconnect during shutdown by turning off all four internal N-channel MOSFETs and isolating the VOUT pin from VIN and PGND. When EN is pulled low, output voltage collapses and no current flows from input to output-even with external pull-ups on VOUT. This behavior is confirmed in the TPS63030DSKR functional description and shutdown current specification (≤0.9 µA).
Is the exposed thermal pad on TPS63030DSKR electrically connected, and how should it be handled?
Yes, the exposed thermal pad on TPS63030DSKR is electrically connected to PGND, as stated in the pin functions table. It must be soldered to a dedicated PGND copper pour on the PCB using ≥4 thermal vias (0.3 mm diameter) to an inner or bottom-layer ground plane. Leaving it floating or connecting it to signal GND violates the TPS63030DSKR thermal and electrical specifications and risks instability or thermal failure.
