Product details
Overview
TPS63000DRCRG4 from Texas Instruments is a high-efficiency, single-inductor buck-boost DC-DC converter optimized for battery-powered systems. It delivers up to 1200 mA at 3.3 V from input voltages between 1.8 V and 5.5 V, supports automatic transition between step-down and boost modes, achieves up to 96% efficiency, and features integrated 1.8-A synchronous switches in a 3-mm × 3-mm 10-pin VSON package - used in portable medical devices and smart phones requiring stable output across wide battery discharge curves.
For engineers reviewing the TPS63000DRCRG4 datasheet, TPS63000DRCRG4 pinout, TPS63000DRCRG4 application, or TPS63000DRCRG4 equivalent, key selection considerations include its fixed 3.3-V output (TPS63001 variant), power-save mode operation, thermal pad grounding requirement, and compatibility with single-cell Li-ion or multi-cell alkaline/NiMH sources.
Technical Context
The TPS63000DRCRG4 implements an average current-mode control architecture with input/output voltage feedforward for fast transient response. Its 4-switch synchronous topology enables seamless buck-to-boost mode transition without external control logic, maintaining regulation when VIN crosses VOUT.
It integrates dual N-channel MOSFETs per switch leg (high-side/low-side), uses separate GND (control) and PGND (power) pins to minimize ground shift, and employs internal loop compensation eliminating need for external compensation components.
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 (2.5–4.2 V) and two/three-cell alkaline (1.8–5.5 V). |
| Output Voltage | Fixed 3.3 V - internally trimmed; FB pin must be connected directly to VOUT for regulation. |
| Max Output Current | 1200 mA at 3.3 V in step-down mode (VIN = 3.6–5.5 V) - sufficient for baseband processors and RF modules. |
| Switch Current Limit | 1800 mA typical - sets peak inductor current limit to prevent saturation during boost operation at low VIN. |
| Efficiency | Up to 96% - achieved via synchronous rectification and optimized gate drive; critical for runtime extension in portable devices. |
| Quiescent Current | <50 μA - enables ultra-low-power operation in standby, extending shelf life of battery-powered medical sensors. |
| Switching Frequency | 1.25–1.5 MHz - allows use of small 2.2-μH inductors and ceramic capacitors for compact PCB layout. |
Pinout & Package
TPS63000DRCRG4 is housed in a thermally enhanced 3-mm × 3-mm, 10-pin VSON (DRC) package with exposed thermal pad connected to PGND. The package supports high-power density designs and requires PCB thermal vias under the pad for reliable operation above 500 mA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Regulated 3.3-V supply rail; connects to output capacitor bank and load; requires low-ESR ceramic decoupling. |
| L1 (Pin 4) | Inductor connection | High-side switch node; connects to one terminal of 2.2-μH inductor; routing must minimize loop area with PGND. |
| L2 (Pin 2) | Inductor connection | Low-side switch node; connects to second inductor terminal; shares same current path as L1 but opposite phase. |
| PGND (Pin 3) | Power ground | Return path for high-current switching paths; must be tied to exposed thermal pad and kept separate from signal GND. |
| VIN (Pin 5) | Main power input | Supplies power stage; accepts 1.8–5.5 V; requires ≥4.7-μF ceramic input capacitor placed adjacent to pin. |
| VINA (Pin 8) | Control supply | Provides bias for control circuitry; must be decoupled independently; UVLO threshold is 1.7 V typical. |
| EN (Pin 6) | Enable input | Active-high logic control; drives device into shutdown (IS < 1 μA) when pulled low; supports system-level power sequencing. |
| PS/SYNC (Pin 7) | Mode control | Low = power-save mode enabled; high = forced PWM; external clock input synchronizes switching to avoid EMI peaks. |
| FB (Pin 10) | Feedback input | Internally connected to 500-mV reference; for fixed-output TPS63000DRCRG4, must be shorted to VOUT. |
| GND (Pin 9) | Signal ground | Reference for EN, PS/SYNC, and internal control circuits; must connect to PGND at single point near GND pin. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamlessly switches between step-down and boost based on VIN/VOUT ratio - eliminates need for external mode control logic. |
| Load disconnect during shutdown | Internal switches isolate VOUT from VIN when EN = low - prevents battery drain through load leakage paths. |
| Overtemperature protection | Shuts down at 140°C junction temperature with 20°C hysteresis - protects against thermal runaway in enclosed handheld enclosures. |
| Synchronous 4-switch topology | Uses four internal N-MOSFETs to achieve >90% efficiency across entire VIN range - reduces external component count and board space. |
| Integrated soft-start | Ramps output voltage while limiting inrush current to ~400 mA - prevents input voltage sag and output overshoot during power-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63020DSJR | Higher 2-A switch current limit; 2.5-MHz switching frequency; supports adjustable output (0.9–5.5 V) via external resistor divider. | Required for loads exceeding 1200 mA or needing programmable output voltage; larger inductor footprint due to higher fSW. | Select TPS63020DSJR when design requires >1.2 A output or flexible VOUT configuration - not drop-in compatible due to different pinout and feedback scheme. |
| MAX77827AEWE+T | Fixed 3.3-V output; 2.2-MHz fSW; lower 1.5-A switch limit; includes I²C interface for dynamic voltage scaling and fault reporting. | Used where system-level power management requires telemetry (e.g., overcurrent alerts, thermal status) or coordinated rail sequencing. | Choose MAX77827AEWE+T only if I²C configurability and fault diagnostics are required - adds software overhead and layout complexity. |
Compared with TPS63000DRCRG4, TPS63020DSJR offers higher current capability and frequency for smaller magnetics but lacks pin compatibility; MAX77827AEWE+T adds digital control at the cost of increased BOM and firmware integration effort - neither is a direct replacement.

FAQ
What is the output voltage configuration of the TPS63000DRCRG4?
The TPS63000DRCRG4 features a fixed 3.3-V output voltage set by internal resistor trimming. Unlike adjustable variants (e.g., TPS63000), it does not require external feedback resistors - the FB pin must be directly connected to VOUT to enable regulation. This simplifies layout and eliminates resistor tolerance errors affecting output accuracy.
Does the TPS63000DRCRG4 support power-save mode, and how is it enabled?
Yes, the TPS63000DRCRG4 supports power-save mode to improve light-load efficiency. It is enabled by pulling the PS/SYNC pin low (≤0.4 V). In this mode, the device discontinues switching when average inductor current drops below ~300 mA and resumes only when output voltage falls below regulation. This reduces quiescent current to <50 μA, extending battery life in standby.
What is the recommended inductor value for the TPS63000DRCRG4?
Texas Instruments recommends a 2.2-μH shielded power inductor (e.g., TDK VLF4012-2R2) for the TPS63000DRCRG4. This value balances ripple current, transient response, and efficiency across the 1.25–1.5 MHz switching frequency range. Inductor saturation current must exceed 1800 mA to accommodate peak switch current during boost operation at minimum VIN.
How should the thermal pad of the TPS63000DRCRG4 be handled on the PCB?
The exposed thermal pad of the TPS63000DRCRG4 must be soldered to a dedicated PGND copper pour and connected to the internal PGND plane using ≥4 thermal vias (0.3-mm diameter, spaced evenly). This ensures effective heat dissipation - critical for maintaining junction temperature below 125°C at 1200 mA output. Failure to properly connect the pad risks thermal shutdown or reduced lifetime.
Can the TPS63000DRCRG4 operate with input voltages below 1.8 V?
No, the TPS63000DRCRG4 has a minimum recommended input voltage of 1.8 V and a startup threshold of 1.9 V on VINA. Operation below 1.8 V violates recommended conditions and may cause erratic behavior or failure to regulate. For sub-1.8-V battery applications, consider TI's TPS63802 or alternative ultra-low-VIN buck-boost converters.
