Product details
Overview
TPS63001DRCRG4 from Texas Instruments is a high-efficiency, single-inductor buck-boost DC-DC converter optimized for battery-powered systems. It delivers a fixed 3.3 V output at up to 1200 mA in step-down mode (VIN = 3.6–5.5 V) and up to 800 mA in boost mode (VIN > 2.4 V), with 96% peak efficiency, 1.8–5.5 V input range, and integrated 1.8-A synchronous switches.
For engineers reviewing the TPS63001DRCRG4 datasheet, TPS63001DRCRG4 pinout, TPS63001DRCRG4 application, or TPS63001DRCRG4 equivalent, this page provides verified functional context, validated pin roles, confirmed thermal and switching specifications, and real-world implementation constraints - including power-save mode behavior, automatic buck/boost transition logic, and dual-ground (GND/PGND) layout requirements.
Technical Context
The TPS63001DRCRG4 employs an average current-mode control architecture with input/output voltage feedforward, enabling fast transient response and stable regulation across wide VIN–VOUT differentials. Its 4-switch synchronous topology dynamically configures one active switch, one rectifying switch, one permanently-on switch, and one permanently-off switch - minimizing RMS current and conduction losses near the buck-boost crossover point.
Control-stage operation includes undervoltage lockout (1.7 V typical on VINA), overtemperature protection (140 °C trip, 20 °C hysteresis), and programmable power-save mode via PS/SYNC pin. The device supports external synchronization (1250–1800 kHz) using a PLL and features soft-start with short-circuit detection based on output voltage ramp rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V - no external feedback divider required; FB pin internally connected to VOUT. |
| 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 (1.8–5.5 V). |
| Max Output Current | 1200 mA at 3.3 V in step-down (VIN ≥ 3.6 V); 800 mA at 3.3 V in boost (VIN > 2.4 V) - defined by thermal limits and switch current capability. |
| Switching Frequency | 1.5 MHz typical - enables compact 2.2 µH inductor and low-profile ceramic capacitors; synchronizable to 1.25–1.8 MHz. |
| Peak Switch Current | 1800 mA typical - sets minimum inductor saturation rating and PCB trace current handling. |
| Quiescent Current | < 50 µA - ensures minimal battery drain during light-load operation in power-save mode. |
| Efficiency | Up to 96% - achieved at mid-load in step-down; drops to ~85% at 10 mA in boost due to gate drive overhead. |
Pinout & Package
TPS63001DRCRG4 is housed in a thermally enhanced 3 mm × 3 mm, 10-pin VSON (DRC) package with exposed thermal pad soldered to PGND for optimal heat dissipation. Pin numbering follows top-view orientation per TI SLVS520C Rev C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Regulated 3.3 V supply node; requires local 10 µF ceramic capacitor to PGND. |
| L1 (Pin 4) | Inductor connection | Connects to one end of series inductor (L1); carries full switching current in both buck and boost phases. |
| L2 (Pin 2) | Inductor connection | Connects to second end of same inductor (L2); forms buck-boost 4-switch node pair with L1. |
| PGND (Pin 3) | Power ground | Return path for high-current switches and inductor; must be isolated from control GND except at single-point tie. |
| VIN (Pin 5) | Main power input | Supplies power stage; accepts 1.8–5.5 V; requires local 10 µF ceramic capacitor to PGND. |
| VINA (Pin 8) | Control supply | Provides bias for internal logic; UVLO threshold 1.7 V; decoupled separately from VIN. |
| EN (Pin 6) | Enable control | Active-high digital enable; pulls device into shutdown (IS < 1 µA) when low; load disconnected from input. |
| PS/SYNC (Pin 7) | Mode control | Low = power-save enabled; high = forced PWM; external clock input for synchronization (1.25–1.8 MHz). |
| GND (Pin 9) | Control ground | Reference for FB, EN, PS/SYNC, and internal error amplifier; must connect to PGND at single point near GND pin. |
| FB (Pin 10) | Feedback input | Internally tied to VOUT for fixed 3.3 V version; not externally accessible - no resistor divider needed. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamless switching between step-down and boost without external control - maintains regulation as VIN crosses VOUT. |
| Load disconnect during shutdown | Internal switches isolate VOUT from VIN when EN = low - prevents battery drain and backfeed into powered loads. |
| Dual-ground architecture (GND/PGND) | Separates sensitive analog reference (GND) from high-current return (PGND) - reduces noise coupling and improves stability. |
| Integrated overtemperature protection | Thermal shutdown at 140 °C with 20 °C hysteresis - prevents permanent damage under sustained overload or poor heatsinking. |
| Soft-start with short-circuit detection | Ramps output voltage while limiting inductor current to ~400 mA until VOUT reaches 1.2 V - avoids inrush and detects hard shorts. |
Applications
| Portable Medical Sensors | Smartphone Power Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS63020DSJR | Same 3.3 V fixed output, but 2.5 MHz switching frequency and higher 2-A switch current rating. | Better suited for ultra-compact designs needing smaller inductors; higher quiescent current (75 µA vs 50 µA). | Select when board space is critical and thermal headroom allows higher switching losses. |
| MAX77827BEWC+T | 3.3 V fixed output, 2.2 MHz, integrated load switch, but only 1.2 A max output and no power-save mode. | Lacks automatic buck-boost transition logic - requires external control for mode selection in some configurations. | Choose when integrated load switch functionality is required and continuous 1.2 A boost operation suffices. |
Compared with TPS63001DRCRG4, TPS63020DSJR offers higher frequency and current headroom at the cost of efficiency at light loads, while MAX77827BEWC+T trades autonomous mode transition for integrated load control - neither is pin-compatible, and all require unique PCB layout and compensation.

FAQ
What is the output voltage configuration of the TPS63001DRCRG4?
The TPS63001DRCRG4 provides a factory-trimmed fixed 3.3 V output. Unlike adjustable variants (e.g., TPS63000), it does not require an external resistor divider - the FB pin is internally connected to VOUT. This simplifies layout and eliminates feedback component tolerance errors, ensuring ±2% output accuracy over temperature and load.
Does the TPS63001DRCRG4 support automatic transition between buck and boost modes?
Yes, the TPS63001DRCRG4 automatically transitions between step-down and boost operation without external intervention. Its control loop continuously monitors VIN and VOUT, reconfiguring the 4-switch topology in real time to maintain regulation - for example, stepping down when VIN = 4.2 V and boosting when VIN drops to 2.5 V, all while sustaining 3.3 V output.
What is the maximum continuous output current for the TPS63001DRCRG4 at 3.3 V?
The TPS63001DRCRG4 delivers up to 1200 mA continuously at 3.3 V when operating in step-down mode (VIN ≥ 3.6 V) and up to 800 mA in boost mode (VIN > 2.4 V). These limits reflect thermal derating and switch current capability - actual achievable current depends on PCB copper area, ambient temperature, and airflow per TI's thermal metrics (RθJA = 46.8 °C/W).
How does the PS/SYNC pin function on the TPS63001DRCRG4?
The PS/SYNC pin on the TPS63001DRCRG4 serves three functions: pulled low (≤0.4 V) enables power-save mode for improved light-load efficiency; pulled high (≥1.2 V) forces fixed-frequency PWM operation; and driven with a 1.25–1.8 MHz clock signal synchronizes switching to an external source via internal PLL - useful for EMI reduction in noise-sensitive systems.
Is the TPS63001DRCRG4 compatible with single-cell Li-ion batteries?
Yes, the TPS63001DRCRG4 is explicitly designed for single-cell Li-ion and Li-polymer batteries, supporting the full discharge range from 4.2 V down to 2.5 V while maintaining regulated 3.3 V output. Its 1.8–5.5 V input range, low quiescent current (<50 µA), and automatic buck-boost transition make it ideal for battery longevity and uninterrupted system operation.
