Product details
Overview
TPS63000DRCT 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 ranging from 1.8 V to 5.5 V, supports automatic transition between step-down and boost modes, operates with ≤50 μA quiescent current, and integrates 1.8-A synchronous switches in a 3-mm × 3-mm VSON-10 package - enabling compact power management in portable medical devices and smart phones.
For engineers reviewing the TPS63000DRCT datasheet, TPS63000DRCT pinout, TPS63000DRCT application, or TPS63000DRCT equivalent, key selection considerations include its fixed 3.3-V output (TPS63001 variant), 96% peak efficiency, 1.25–1.5 MHz switching frequency, thermal shutdown at 140°C, and dual-ground architecture (GND/PGND) for noise-sensitive analog subsystems.
Technical Context
The TPS63000DRCT implements an average current-mode control topology with input/output voltage feedforward for fast transient response. Its four-NMOS switch architecture dynamically configures as buck or boost based on VIN vs VOUT relationship - using one active, one rectifying, one permanently-on, and one permanently-off switch to minimize RMS current and conduction losses near the VIN = VOUT crossover region.
It features dual ground separation (GND for control logic, PGND for power switches), internal loop compensation, undervoltage lockout (1.7 V typical on VINA), and programmable power-save mode via PS/SYNC pin. The FB pin is internally connected to VOUT for fixed-output variants, eliminating external resistor divider requirements.
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 (1.8–5.5 V) |
| Output Voltage | Fixed 3.3 V - no external feedback resistors required; FB internally tied to VOUT |
| Max Output Current | 1200 mA at 3.3 V (VIN ≥ 3.6 V) - enables direct powering of 3.3-V microcontrollers and RF modules |
| Switch Current Limit | 1800 mA typical - ensures safe operation under short-circuit and heavy transient loads |
| Efficiency | Up to 96% - reduces thermal load and extends battery runtime in portable applications |
| Quiescent Current | <50 μA - preserves battery life during system sleep or standby states |
| Switching Frequency | 1.25–1.5 MHz - allows use of small 2.2-μH inductors and ceramic capacitors for space-constrained PCBs |
Pinout & Package
TPS63000DRCT is housed in a thermally enhanced 3-mm × 3-mm, 10-pin VSON (DRC) package with exposed thermal pad soldered to PGND. Pin numbering follows top-view orientation with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Regulated 3.3-V supply rail; requires low-ESR ceramic capacitor (≥10 μF) placed adjacent to pin |
| L1 (Pin 4) | Inductor connection | Connects to first terminal of 2.2-μH power inductor; carries high-frequency AC current in both buck and boost modes |
| L2 (Pin 2) | Inductor connection | Connects to second terminal of same inductor; forms buck-boost energy transfer path with L1 |
| VIN (Pin 5) | Main power input | Supplies power stage; must be decoupled with ≥4.7-μF ceramic capacitor close to pin and PGND |
| VINA (Pin 8) | Control-stage supply | Provides bias for internal logic; shares UVLO threshold (1.7 V) with VIN but has separate decoupling path |
| EN (Pin 6) | Enable control | Active-high digital input; pulls device into shutdown (≤1 μA IS) when low; disconnects load from input |
| PS/SYNC (Pin 7) | Mode control | Low = power-save mode enabled; high = forced PWM; external clock input synchronizes switching frequency |
| FB (Pin 10) | Feedback reference | Internally connected to VOUT for fixed 3.3-V operation; no external divider needed |
| GND (Pin 9) | Logic ground | Reference for EN, PS/SYNC, and internal control circuitry; must connect to PGND at single point near GND pin |
| PGND (Pin 3) | Power ground | Return path for high-current switches and inductor; connects directly to exposed thermal pad |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamlessly shifts between step-down and boost without external control or mode pins - maintains regulation across full VIN range |
| Load disconnect during shutdown | Isolates output from input when EN = low - prevents battery drain and backfeed in system-level power sequencing |
| Dual ground architecture (GND/PGND) | Separates noise-sensitive control logic from high-current power paths - improves stability in mixed-signal designs |
| Integrated overtemperature protection | Shuts down at 140°C junction temperature with 20°C hysteresis - prevents thermal runaway without external sensors |
| Synchronous 4-switch topology | Eliminates external diodes and achieves >90% efficiency down to 10-mA loads - reduces BOM count and board area |

FAQ
What output voltage does the TPS63000DRCT provide?
The TPS63000DRCT provides a fixed 3.3-V output. Unlike adjustable variants such as TPS63000 or TPS63002, it does not require external feedback resistors because the FB pin is internally connected to VOUT. This simplifies layout and reduces component count for designs needing only 3.3 V, and is confirmed in the device's datasheet section "Device Information" and "Pin Functions".
Does the TPS63000DRCT support automatic buck-boost mode switching?
Yes, the TPS63000DRCT automatically transitions between step-down and boost modes based on input-to-output voltage relationship. When VIN exceeds VOUT (3.3 V), it operates as a buck converter; when VIN falls below 3.3 V, it seamlessly switches to boost mode - all without external control signals. This behavior is explicitly documented in the "Features" and "Description" sections of the SLVS520C datasheet.
What is the maximum continuous output current of the TPS63000DRCT at 3.3 V?
The TPS63000DRCT delivers up to 1200 mA continuously at 3.3 V when VIN is between 3.6 V and 5.5 V (step-down mode). In boost mode (e.g., VIN = 2.4 V), it supports up to 800 mA at 3.3 V. These values are specified in the "Features" table and verified in Figure 1 ("Maximum Output Current vs Input Voltage") of the SLVS520C datasheet.
How does the TPS63000DRCT manage thermal performance in compact layouts?
The TPS63000DRCT uses a 3-mm × 3-mm VSON package with an exposed thermal pad connected to PGND, achieving a junction-to-board thermal resistance (RθJB) of 21.4°C/W. Combined with overtemperature protection that disables operation above 140°C (with 20°C hysteresis), it sustains reliable operation in sealed enclosures - as validated in the "Thermal Information" and "Overtemperature Protection" sections of the datasheet.
Can the TPS63000DRCT be synchronized to an external clock?
Yes, the PS/SYNC pin of the TPS63000DRCT accepts an external clock signal (1.25–1.8 MHz) to synchronize switching frequency, reducing EMI in noise-sensitive systems. When PS/SYNC is pulled high, the device operates in forced PWM mode; when pulled low, power-save mode activates. This functionality is detailed in section "7.4.3 Power-Save Mode and Synchronization" of the SLVS520C datasheet.
