Product details
Overview
TPS63002DRCR 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 800 mA at 5 V in boost mode (VIN > 2.4 V), achieves up to 96% peak efficiency, and integrates four synchronous N-channel MOSFETs for seamless automatic transition between buck and boost operation - used in portable medical devices and smart handhelds requiring stable 5-V rail generation from declining battery sources.
For engineers reviewing the TPS63002DRCR datasheet, TPS63002DRCR pinout, TPS63002DRCR application, or TPS63002DRCR equivalent, key selection considerations include its fixed 5-V output, 10-pin VSON (3 mm × 3 mm) package with separate PGND/GND pins, power-save mode enable via PS/SYNC, undervoltage lockout at ~1.7 V on VINA, and thermal shutdown at 140°C - all critical for battery life optimization and robust low-voltage operation.
Technical Context
The TPS63002DRCR implements 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, and two static switches (one ON, one OFF) to minimize conduction and switching losses - especially near the buck-boost crossover region.
It features dual ground separation (GND for control logic, PGND for power switches), internal loop compensation, soft-start with current-limit ramping, and overtemperature protection with 20°C hysteresis. The FB pin is internally tied to VOUT for fixed 5-V operation, eliminating external resistor divider requirements while maintaining ±0.5% load/line regulation.
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). |
| Fixed Output Voltage | 5.0 V ±2% - factory-trimmed internal feedback divider; no external resistors required. |
| Max Output Current | 800 mA at 5 V in boost mode (VIN > 2.4 V) - sufficient for USB-peripheral interfaces and 5-V microcontrollers. |
| Peak Efficiency | 96% - achieved at mid-load with VIN = 3.6 V, VOUT = 5 V, minimizing thermal stress and extending battery runtime. |
| Switching Frequency | 1.25 MHz to 1.5 MHz (typical) - enables use of compact 2.2 µH inductors and reduces EMI compared to sub-MHz converters. |
| Quiescent Current | <50 µA - ensures minimal battery drain during light-load or standby operation in portable devices. |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |
Pinout & Package
TPS63002DRCR is housed in a thermally enhanced 10-pin VSON (DRC) package measuring 3.0 mm × 3.0 mm with an exposed thermal pad connected to PGND. The package supports high-power density layouts and requires controlled-impedance PCB routing for L1/L2 inductor connections and low-ESR ceramic capacitors on VIN/VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Power output | Delivers regulated 5-V supply; must connect to 10-µF ceramic capacitor and load with short, low-inductance path to PGND. |
| L1 (Pin 4) | Inductor connection (buck path) | Connects to one terminal of 2.2-µH inductor; carries high-current pulsed waveform during buck operation. |
| L2 (Pin 2) | Inductor connection (boost path) | Connects to other inductor terminal; carries complementary high-current pulsed waveform during boost operation. |
| PGND (Pin 3) | Power ground | Return path for high-switching currents; must be tied to exposed thermal pad and routed separately from GND. |
| VIN (Pin 5) | Main power input | Supplies power stage; requires ≥4.7-µF ceramic capacitor placed adjacent to pin and PGND. |
| VINA (Pin 8) | Control-stage supply | Provides bias for internal logic; shares input source with VIN but must meet UVLO threshold (1.7 V min) independently. |
| EN (Pin 6) | Enable control | Active-high logic input; pulls device into shutdown (IS < 1 µA) when low, disconnecting load from input. |
| PS/SYNC (Pin 7) | Mode control / sync input | Low = enable power-save mode; high = forced PWM; external clock input synchronizes switching frequency. |
| GND (Pin 9) | Logic ground | Reference for EN, PS/SYNC, and internal control circuitry; must connect to PGND at single point near GND pin. |
| FB (Pin 10) | Feedback input | Internally connected to VOUT for fixed 5-V operation; left unconnected externally per datasheet guidance. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic buck-boost mode transition | Seamlessly shifts between step-down and step-up based on VIN–VOUT relationship - eliminates manual mode selection and maintains regulation down to 2.5 V input. |
| Separate GND and PGND pins | Prevents ground bounce and noise coupling from high di/dt power paths into sensitive control circuitry - improves stability and EMI performance. |
| Load disconnect during shutdown | Internal switches isolate VOUT from VIN when EN = low - prevents battery drain through parasitic loads and enables true system power gating. |
| Programmable power-save mode | Reduces switching activity at light loads via PS/SYNC pin, lowering quiescent current to <50 µA without compromising startup time or regulation accuracy. |
| Integrated overtemperature protection | Shuts down at 140°C junction temperature and auto-restarts after 20°C cooldown - provides fail-safe thermal management without external sensors. |

FAQ
What is the output voltage of the TPS63002DRCR?
The TPS63002DRCR is a fixed-output buck-boost converter with a factory-trimmed 5.0-V nominal output voltage, specified over temperature and load with ±2% tolerance. Unlike adjustable variants (e.g., TPS63000), it requires no external feedback resistors - the FB pin is internally connected to VOUT, simplifying design and reducing component count.
Does the TPS63002DRCR support automatic buck-boost mode switching?
Yes, the TPS63002DRCR automatically transitions between step-down and step-up operation based on real-time comparison of VIN and VOUT. When VIN exceeds 5 V, it operates in buck mode; when VIN falls below 5 V, it seamlessly shifts to boost mode - all without external control or mode pins, ensuring uninterrupted 5-V regulation across the full 1.8–5.5-V input range.
What is the maximum output current capability of the TPS63002DRCR?
The TPS63002DRCR delivers up to 800 mA at 5 V when operating in boost mode (VIN > 2.4 V), and up to 1200 mA in step-down mode (VIN = 3.6 V to 5.5 V). Actual achievable current depends on input voltage, ambient temperature, PCB thermal design, and inductor selection - with thermal derating beginning above 85°C ambient.
How does the PS/SYNC pin function on the TPS63002DRCR?
The PS/SYNC pin on the TPS63002DRCR 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 signal (1.25–1.8 MHz) to synchronize switching - all using standard logic thresholds without additional level-shifting circuitry.
Is the TPS63002DRCR RoHS-compliant and lead-free?
Yes, the TPS63002DRCR is manufactured in accordance with RoHS Directive 2011/65/EU and is lead-free, halogen-free, and compliant with TI's environmental standards. The DRC package uses matte tin (Sn) lead finish and meets JEDEC J-STD-020 moisture sensitivity level 2a (MSL-2a) for surface-mount assembly.
