Product details
Overview
TPS63030DSKTG4 from Texas Instruments is a high-efficiency, single-inductor buck-boost DC/DC converter IC designed for battery-powered systems requiring regulated output across varying input voltages. It supports 1.8 V to 5.5 V input, delivers adjustable output from 1.2 V to 5.5 V, achieves up to 96% efficiency, sustains 800 mA at 3.3 V in step-down mode (VIN = 3.6 V), and operates with <35 μA quiescent current - enabling use in portable medical monitors and handheld data terminals.
For engineers reviewing the TPS63030DSKTG4 datasheet, TPS63030DSKTG4 pinout, TPS63030DSKTG4 application, or TPS63030DSKTG4 equivalent, key selection criteria include its automatic buck-boost transition, 1-A switch current limit, 2.5-mm × 2.5-mm VSON-10 package, power-save mode enablement via PS/SYNC pin, and fixed-frequency synchronization capability.
Technical Context
The TPS63030DSKTG4 implements an average current-mode control architecture with dual-loop regulation: a fast inner current loop stabilizes inductor current, while an outer voltage loop maintains precise output regulation using feedback from the FB pin. Input and output voltage feed-forward enables rapid transient response during line or load changes.
Its four-NMOS synchronous switch topology dynamically configures conduction paths - operating as a buck converter when VIN > VOUT and as a boost when VIN < VOUT - while keeping two switches static per mode to minimize switching losses. The device integrates undervoltage lockout (1.5 V threshold on VINA), overtemperature protection (140°C trip), and soft-start with controlled current ramp-up.
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 pre-regulation |
| Output Voltage Range | 1.2 V to 5.5 V (adjustable) - set via external resistor divider on FB pin; internal reference is 500 mV ±1% |
| Max Output Current | 800 mA at 3.3 V in step-down (VIN ≥ 3.6 V); 500 mA at 3.3 V in boost (VIN ≥ 2.4 V) - defined by thermal and switch-current limits |
| Switching Frequency | 2.4 MHz typical - enables compact 1.5-μH inductor and low-profile ceramic capacitors; synchronizable via PS/SYNC pin |
| Quiescent Current | 35 μA typical - ensures >100-hour runtime in always-on portable devices with 100-mAh battery |
| Efficiency Peak | 96% - achieved at mid-load in buck or boost mode; maintained down to 10 mA via power-save mode |
| Thermal Resistance | RθJA = 60.7°C/W - requires minimal PCB copper area for thermal management in 2.5-mm × 2.5-mm DSK package |
Pinout & Package
TPS63030DSKTG4 is housed in a thermally enhanced 10-pin VSON (DSK) package measuring 2.5 mm × 2.5 mm with an exposed thermal pad connected to PGND. The package supports tape-and-reel delivery (T suffix) and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Regulated buck-boost output node; connects directly to output capacitor bank and load |
| L1 (Pin 4) | Inductor connection | High-side switch node for first inductor leg; must be routed with low-inductance path to L1 |
| L2 (Pin 2) | Inductor connection | Low-side switch node for second inductor leg; shares return path with PGND |
| PGND (Pin 3) | Power ground | Return path for high-current switch paths; must be tied to exposed thermal pad and separated from signal GND |
| VIN (Pin 5) | Power stage supply | Input supply for high-current NMOS switches; requires local 10-μF ceramic decoupling |
| VINA (Pin 8) | Control stage supply | Supply for bias circuitry and logic; requires 0.1-μF bypass to GND; triggers UVLO at 1.5 V |
| EN (Pin 6) | Enable control | Active-high digital enable; pulls device into shutdown (<0.9 μA ISHDN) when low |
| PS/SYNC (Pin 7) | Mode control | Low = power-save enabled; high = fixed-frequency operation; external clock accepted for synchronization |
| FB (Pin 10) | Voltage feedback | Senses output via resistor divider (adjustable) or direct connection to VOUT (fixed versions); 500 mV reference |
| GND (Pin 9) | Signal ground | Reference for all control circuitry; must connect to PGND at single point near GND pin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63031DSKTG4 | Fixed 3.3-V output; FB pin internally tied to VOUT; no external resistor divider required | Eliminates two resistors and layout area; less flexible for multi-rail designs needing different voltages | Select when system requires only 3.3 V and board space is constrained |
| MP2155GQZ-P | 2.5-V to 5.5-V input; 0.6-V to 5.5-V adjustable output; 2-MHz switching; 1.2-A switch current | Higher peak current but lower max efficiency (94% vs. 96%); different pinout and thermal pad configuration | Select when higher output current headroom is needed and thermal design accommodates alternate layout |
Compared with TPS63030DSKTG4, TPS63031DSKTG4 simplifies BOM and layout for fixed 3.3-V use cases, while MP2155GQZ-P offers greater current capacity at the cost of slightly reduced efficiency and non-drop-in packaging - making TPS63030DSKTG4 optimal for space-constrained, adjustable-voltage, battery-life-critical designs.

FAQ
What is the recommended inductor value for TPS63030DSKTG4 in a 3.3-V output design?
The recommended inductor value for TPS63030DSKTG4 in a 3.3-V output application is 1.5 µH, as validated in TI's typical application circuits. This value balances inductor ripple current, transient response, and efficiency across both buck and boost modes. Coilcraft LPS3015-1R5 or Murata LQH3NP series are qualified alternatives meeting DC resistance (<80 mΩ) and saturation current (>1.5 A) requirements.
Does TPS63030DSKTG4 require external compensation components?
No, TPS63030DSKTG4 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. Layout adherence - especially tight PGND/GND separation and short high-current paths - is sufficient to ensure robust loop stability across temperature and load conditions.
How does the PS/SYNC pin function on TPS63030DSKTG4?
On TPS63030DSKTG4, the PS/SYNC pin serves three functions: pulled low (≤0.4 V) enables power-save mode for light-load efficiency; pulled high (≥1.2 V) forces fixed-frequency PWM operation; and driven with a 2.2–2.6 MHz external clock synchronizes switching via internal PLL. The pin accepts standard logic thresholds and tolerates missing clock edges without malfunction.
Can TPS63030DSKTG4 operate with input voltage below 1.8 V?
TPS63030DSKTG4 has a recommended minimum input voltage of 1.8 V, with guaranteed start-up at 1.8 V (typical 1.6 V, max 1.9 V). Operation below 1.8 V is not specified and may result in unstable regulation or failure to start. For sub-1.8-V battery applications, consider TI's TPS63802 or alternative ultra-low-VIN buck-boost converters with verified 0.5-V start-up capability.
What is the thermal pad connection requirement for TPS63030DSKTG4?
The exposed thermal pad of TPS63030DSKTG4 must be soldered to a dedicated PGND copper pour on the PCB and electrically connected to Pin 3 (PGND). TI recommends a 2.5-mm × 2.5-mm thermal pad with 4–9 thermal vias (0.3-mm diameter) to an internal or bottom-layer ground plane to achieve the specified RθJA of 60.7°C/W and prevent thermal shutdown under 800-mA continuous load.
