Product details
Overview
TPS63002DRCT from Texas Instruments is a fixed-output 5-V buck-boost DC-DC converter IC designed for single-cell Li-ion/Li-polymer and multi-cell alkaline/NiMH battery-powered systems. It operates across 1.8 V to 5.5 V input, delivers up to 1200 mA at 5 V in step-down mode (VIN ≥ 3.6 V), achieves up to 96% peak efficiency, and integrates dual synchronous switches with automatic mode transition between buck and boost topologies. It is used in portable medical devices requiring stable 5-V rail generation from depleting battery sources.
For engineers reviewing the TPS63002DRCT datasheet, TPS63002DRCT pinout, TPS63002DRCT application, or TPS63002DRCT equivalent, key selection considerations include its fixed 5-V output, 10-pin VSON package with separate PGND/GND pins, power-save mode enable via PS/SYNC, load disconnect during shutdown, and thermal protection - all critical for compact, battery-sensitive designs.
Technical Context
The TPS63002DRCT implements an average current-mode control architecture with input/output voltage feedforward for fast transient response. Its 4-switch synchronous buck-boost topology uses one active switch, one rectifying switch, and two statically biased MOSFETs - minimizing switching losses near VIN ≈ VOUT while maintaining >90% efficiency across 10 mA–1 A loads.
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 overtemperature shutdown (140°C threshold with 20°C hysteresis). The FB pin is internally tied to VOUT for fixed 5-V operation, eliminating external resistor divider requirements.
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 V cutoff) and operation from two/three-cell alkaline (1.8 V start) |
| Output Voltage | Fixed 5.0 V ±2% - trimmed internal feedback divider eliminates external resistors and layout sensitivity |
| Max Output Current | 1200 mA at 5 V in step-down mode (VIN = 3.6–5.5 V) - sufficient for USB-peripheral interfaces and sensor hubs |
| Peak Efficiency | 96% at 500 mA, VIN = 3.6 V - reduces thermal stress in sealed enclosures and extends battery runtime |
| Switching Frequency | 1.5 MHz typical - enables use of small 2.2 µH inductors and <22 µF total ceramic output capacitance |
| Quiescent Current | 50 µA - maintains >100-hour shelf life in always-on portable monitors with coin-cell backup |
| Thermal Shutdown | 140°C junction temperature - protects against PCB hotspots in high-density layouts without external thermal sensors |
Pinout & Package
TPS63002DRCT 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 ≤46.8°C/W junction-to-ambient thermal resistance under standard JEDEC PCB conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Delivers regulated 5-V supply; requires low-ESR ceramic capacitor (≥15 µF) placed adjacent to pin and PGND |
| 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 4-switch buck-boost node with L1 and internal MOSFETs |
| PGND (Pin 3) | Power ground | Return path for high-current switch nodes; must be connected to thermal pad and routed separately from control GND |
| GND (Pin 9) | Control ground | Reference for EN, PS/SYNC, FB, and internal error amplifier; connects to analog ground plane only |
| VIN (Pin 5) | Power stage supply | Primary input for high-current path; accepts 1.8–5.5 V; requires local 4.7 µF ceramic decoupling |
| VINA (Pin 8) | Control stage supply | Bias supply for internal regulator and logic; shares UVLO threshold (1.7 V) with VIN but has independent current path |
| EN (Pin 6) | Enable input | Active-high digital control; pulls device into shutdown (<1 µA IQ) when low, disconnecting load from input |
| PS/SYNC (Pin 7) | Mode control | Low = power-save mode enabled; high = forced PWM; external clock input synchronizes switching to 1.25–1.8 MHz |
| FB (Pin 10) | Feedback input | Internally shorted to VOUT for fixed 5-V operation; no external components required |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost transition | Seamlessly shifts between step-down and boost operation as VIN crosses 5 V - eliminates manual mode selection and output glitches |
| Load disconnect during shutdown | Internal switches isolate VOUT from VIN when EN = low - prevents battery drain through downstream circuitry |
| Dual ground architecture (GND/PGND) | Prevents control-loop noise coupling from high di/dt power paths - improves stability without complex PCB partitioning |
| Integrated 1.8-A switches | 100-mΩ high-side and low-side MOSFETs support full 1200-mA load at 5 V with <100 mV dropout in step-down mode |
| Power-save mode with hysteresis | Disables switching below ~300 mA load while maintaining regulation; resumes instantly upon load increase - extends light-load battery life |
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 |
|---|---|---|---|
| TPS63001DRCT | Fixed 3.3-V output; identical pinout, package, and control features | Requires redesign of downstream 5-V circuitry; suitable only if system can accept 3.3-V rail | Select when 3.3-V logic supply is needed instead of 5-V - no layout change required |
| MAX77827BEWL+T | Fixed 5-V output; 2.5-MHz switching; higher 2-A switch current rating; different 12-pin WLP package | Supports higher peak loads (up to 1.8 A); requires PCB redesign due to non-compatible footprint and pin mapping | Choose for applications needing >1.2-A sustained output or tighter EMI control via higher frequency |
Compared with TPS63001DRCT, the TPS63002DRCT provides +1.7-V higher output for USB/peripheral compatibility but shares identical thermal performance and shutdown behavior; versus MAX77827BEWL+T, it offers proven layout compatibility and lower BOM cost at the expense of peak current headroom.

FAQ
What is the output voltage setting of the TPS63002DRCT?
The TPS63002DRCT is factory-trimmed for a fixed 5.0-V output with ±2% tolerance across temperature and load. Unlike adjustable variants (e.g., TPS63000), it does not require external feedback resistors - the FB pin is internally connected to VOUT, simplifying layout and improving accuracy.
Does the TPS63002DRCT support automatic transition between buck and boost modes?
Yes, the TPS63002DRCT automatically transitions between step-down and boost operation based on real-time comparison of VIN and VOUT. When VIN exceeds 5 V, it operates as a buck converter; when VIN falls below 5 V, it seamlessly switches to boost - all without external control or output interruption.
What is the maximum continuous output current capability of the TPS63002DRCT?
The TPS63002DRCT delivers up to 1200 mA continuously at 5 V when VIN is between 3.6 V and 5.5 V (step-down mode). In boost mode (VIN < 5 V), maximum output current decreases with input voltage - e.g., 800 mA at VIN = 2.4 V - as specified in the electrical characteristics table.
How does the PS/SYNC pin function on the TPS63002DRCT?
The PS/SYNC pin on the TPS63002DRCT serves three functions: pulled low to enable power-save mode (improving light-load efficiency), pulled high to force fixed-frequency PWM operation, or driven with an external clock (1.25–1.8 MHz) to synchronize switching - reducing EMI in noise-sensitive systems.
Is thermal management required for the TPS63002DRCT in standard PCB layouts?
Yes - the TPS63002DRCT's exposed thermal pad must be soldered to a dedicated copper pour connected to PGND. With RθJA = 46.8°C/W, ambient temperatures above 65°C or continuous >800-mA loads require ≥250 mm² of 2-oz copper under the DRC package to maintain TJ < 125°C per recommended operating conditions.
