Product details
Overview
TPS63000DRCTG4 from Texas Instruments is a high-efficiency, single-inductor buck-boost DC-DC converter optimized for battery-powered systems. It operates from 1.8 V to 5.5 V input, delivers up to 1200 mA at 3.3 V output, and features automatic transition between step-down and boost modes - enabling stable 3.3 V rail generation from single-cell Li-ion (2.5–4.2 V) or two-cell alkaline (2.4–3.6 V) sources in portable medical devices and smart audio players.
For engineers reviewing the TPS63000DRCTG4 datasheet, TPS63000DRCTG4 pinout, TPS63000DRCTG4 application, or TPS63000DRCTG4 equivalent, key selection criteria include its 96% peak efficiency, 1.8-A internal switch current limit, 1.2–5.5 V adjustable output range, power-save mode for <50 μA quiescent current, and thermal shutdown protection - all in a compact 3 mm × 3 mm VSON-10 package with dual ground (GND/PGND) separation.
Technical Context
The TPS63000DRCTG4 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 during buck, boost, or near-unity conversion.
It integrates undervoltage lockout (1.7 V typical), overtemperature protection (140 °C trip), soft-start with short-circuit detection, and programmable power-save mode via PS/SYNC pin. The FB pin senses 500 mV reference for adjustable outputs; fixed-output variants tie FB directly to VOUT - but TPS63000DRCTG4 is the adjustable version requiring external resistor divider.
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-cell alkaline/NiMH (2.4–3.6 V), and USB-powered systems without external LDO pre-regulation. |
| Output Voltage Range | 1.2 V to 5.5 V (adjustable) - set via external resistor divider on FB pin; typical 500 mV feedback threshold enables precise regulation. |
| Max Output Current | 1200 mA at 3.3 V (VIN = 3.6–5.5 V, step-down); 800 mA at 3.3 V (VIN > 2.4 V, boost) - sufficient for microcontroller cores, RF transceivers, and display bias rails. |
| Peak Switch Current | 1800 mA typical - limits inductor saturation risk and ensures safe operation under load transients and low-VIN boost conditions. |
| Quiescent Current | <50 μA in power-save mode - extends battery life in always-on sensor nodes and wearable standby states. |
| Switching Frequency | 1.25 MHz to 1.5 MHz (typical), synchronizable up to 1.8 MHz - enables use of small 2.2 μH inductors and reduces EMI filtering burden. |
| Efficiency | Up to 96% - achieved via synchronous rectification and optimized gate drive, critical for thermal management in sealed enclosures. |
Pinout & Package
TPS63000DRCTG4 is housed in a thermally enhanced 3 mm × 3 mm, 10-pin VSON (DRC) package with exposed thermal pad connected to PGND. Dual ground separation (GND for control logic, PGND for power switches) minimizes noise coupling and improves stability in high-current switching.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power stage input supply | Connects to main battery or input source; must be decoupled with ≥4.7 μF ceramic capacitor close to pin. |
| VINA | Control stage input supply | Provides bias for internal logic; shares input with VIN but benefits from separate local decoupling for noise immunity. |
| EN | Enable control input | Active-high logic signal; pulls low to disconnect load from input and reduce shutdown current to ≤1 μA. |
| PS/SYNC | Power-save enable / clock sync input | Low = enable power-save mode; high = forced PWM; external clock input synchronizes switching to system timing. |
| GND | Control ground reference | Reference for EN, PS/SYNC, FB; must connect to PGND at single point near GND pin to avoid ground bounce. |
| PGND | Power ground return | Return path for high-current switches and inductors; connects to exposed thermal pad for thermal dissipation. |
| L1, L2 | Inductor connection terminals | Interface with single 2.2 μH inductor; polarity matters - L1 connects to VIN side, L2 to VOUT side per layout guidelines. |
| VOUT | Regulated output | Delivers buck-boost regulated voltage; requires ≥15 μF ceramic output capacitance placed adjacent to VOUT/PGND. |
| FB | Feedback input | Senses output via resistor divider; 500 mV reference enables precise output programming (e.g., R1=1 MΩ, R2=200 kΩ for 3.3 V). |
Key Features
| Feature | Design Value |
|---|---|
| Single-inductor buck-boost topology | Eliminates need for separate buck + boost ICs or complex multi-inductor designs - reduces BOM count and PCB area by ~40% vs dual-converter solutions. |
| Automatic mode transition | Seamlessly shifts between step-down and boost operation as VIN crosses VOUT - maintains regulation without output glitch or manual reconfiguration. |
| Load disconnect during shutdown | Internally opens power path when EN = low - prevents battery drain through output capacitors or downstream circuitry in sleep mode. |
| Integrated overtemperature protection | Shuts down at 140 °C with 20 °C hysteresis - protects against thermal runaway in enclosed handhelds without external thermal sensors. |
| Separate GND and PGND pins | Isolates sensitive control signals from high di/dt power return paths - improves PSRR and reduces output voltage ripple by up to 15 mVpp. |

FAQ
What output voltage does TPS63000DRCTG4 deliver by default?
The TPS63000DRCTG4 is an adjustable-output buck-boost converter with no factory-set voltage. Its output is determined by an external resistor divider connected to the FB pin, which references a precise 500 mV internal bandgap. For example, using R1 = 1 MΩ and R2 = 200 kΩ yields 3.3 V. Fixed-output versions (e.g., TPS63001) exist separately, but TPS63000DRCTG4 requires external programming to set VOUT anywhere from 1.2 V to 5.5 V.
Does TPS63000DRCTG4 support synchronization to an external clock?
Yes, TPS63000DRCTG4 supports external clock synchronization via the PS/SYNC pin. When a logic-level clock signal (1.25–1.8 MHz) is applied, the device's internal PLL locks to the external frequency - enabling EMI reduction through spread-spectrum alignment and deterministic timing in multi-rail systems. This feature is confirmed in the Electrical Characteristics table and Functional Block Diagram of the SLVS520C datasheet.
How does TPS63000DRCTG4 handle input voltage crossing the output voltage threshold?
The TPS63000DRCTG4 automatically transitions between buck and boost modes without interruption or output disturbance when VIN crosses VOUT. Its control loop continuously monitors both voltages and adjusts switch configuration in real time - using one active switch, one rectifying switch, and two static switches - ensuring continuous regulation and <1% output deviation during crossover, as verified in Figure 11 and Figure 12 of the datasheet.
What is the maximum recommended output capacitance for TPS63000DRCTG4?
There is no upper limit on output capacitance for TPS63000DRCTG4. The datasheet explicitly states "no upper limit" and recommends ≥15 μF ceramic capacitance placed close to VOUT and PGND. Larger values (e.g., 47–100 μF) further reduce output voltage ripple and improve load transient response - particularly beneficial in noise-sensitive applications like audio codecs or precision ADCs powered by the TPS63000DRCTG4.
Can TPS63000DRCTG4 operate with a single 1.5 V alkaline cell?
No, TPS63000DRCTG4 cannot start or operate from a single 1.5 V alkaline cell. Its absolute minimum input voltage for startup is 1.9 V (per Recommended Operating Conditions), and the guaranteed operating range begins at 1.8 V. A single alkaline cell drops below 1.8 V early in discharge; therefore, TPS63000DRCTG4 requires at least two alkaline cells (2.4–3.2 V) or one Li-ion/Li-polymer cell (2.5–4.2 V) to function reliably across its full load range.
