Product details
Overview
TPS630701RNMR from Texas Instruments is a fixed 5-V output, synchronous buck-boost DC/DC converter supporting 2.0 V to 16 V input and delivering up to 2 A in both buck and boost modes with 95% peak efficiency, ±1% PWM-mode output accuracy, and integrated power good (PG) signaling. It serves as the primary voltage regulator in portable battery-powered systems where input voltage may dip below or rise above nominal output.
For engineers reviewing the TPS630701RNMR datasheet, TPS630701RNMR pinout, TPS630701RNMR application, or TPS630701RNMR equivalent, key selection considerations include its fixed 5-V output, QFN-15 package with thermal pad, automatic buck/boost mode transition, 2.4 MHz switching frequency with synchronization capability, and built-in overvoltage/overtemperature protection.
Technical Context
The TPS630701RNMR implements an average current-mode control architecture using four internal N-channel MOSFETs-two for buck operation and two for boost-with seamless automatic mode transition based on VIN/VOUT ratio. Its dual-path switching ensures minimal RMS inductor current and conduction loss across the full 2.0–16 V input range.
It integrates a precision enable input (0.8 V threshold), programmable soft-start (400–850 µs), power-good monitoring (94.5–98.5% VOUT threshold), and PS/SYNC pin supporting forced PWM, PFM, or external clock synchronization between 2.1–2.8 MHz. The device also features output discharge disable (distinct from TPS630702) and load disconnect during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.0 V to 16 V - supports single-cell Li-ion (2.7–4.2 V), dual-cell (5.4–8.4 V), and wide-input industrial rails without pre-regulation. |
| Output Voltage | Fixed 5.0 V - eliminates external feedback resistors; ±1% dc accuracy in PWM mode ensures stable USB-compliant bus regulation. |
| Max Output Current | 2 A - sustained in both buck (VIN ≥ 4.5 V) and boost (VIN ≤ 4.5 V) configurations, enabling direct powering of USB peripherals or SoC cores. |
| Peak Efficiency | 95% - achieved at mid-load (e.g., 1 A @ 5 V out, 7.2 V in), minimizing thermal stress and extending battery runtime in portable designs. |
| Switching Frequency | 2.4 MHz (typical) - enables use of compact 1.5 µH inductors and low-ESR ceramic capacitors; supports external sync up to 2.8 MHz for EMI control. |
| Quiescent Current | 54 µA (typical, PFM mode) - maintains ultra-low standby power draw critical for always-on IoT sensors and medical wearables. |
| Thermal Protection | 160 °C shutdown with 20 °C hysteresis - prevents permanent damage during transient overload or poor PCB thermal design. |
Pinout & Package
The TPS630701RNMR is housed in a thermally enhanced 2.5 mm × 3 mm, 15-pin VQFN package with exposed thermal pad (RNMR suffix), optimized for high-power density and efficient heat dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 14) | Enable control input | Logic-high (>0.8 V) enables regulation; precise 0.7–0.83 V rising threshold allows RC-based sequencing and user-defined UVLO. |
| FB (Pin 5) | Feedback reference | Internally connected to VOUT in fixed-5V version; no external resistor required-simplifies layout and improves stability. |
| PG (Pin 2) | Open-drain power-good indicator | Signals regulated output (high-Z when VOUT ≥94.5% of 5 V); requires external pull-up to monitor system readiness. |
| VIN (Pins 12, 13) | Main power input | Accepts 2.0–16 V; dual pins reduce trace resistance and improve current handling for high-input-current scenarios. |
| VOUT (Pins 7, 8) | Regulated output | Delivers fixed 5 V; dual pins lower output impedance and support higher continuous current delivery. |
| L1 / L2 (Pins 11, 9) | Inductor connections | Interface with external 1.5 µH inductors; L1 connects to high-side buck/low-side boost switch; L2 to low-side buck/high-side boost switch. |
| PGND (Pin 10) | Power ground return | Dedicated low-impedance path for high-frequency switching currents-must be isolated from signal GND to prevent noise coupling. |
| PS/SYNC (Pin 1) | Mode control & sync input | Pull high for auto PFM/PWM; pull low for forced 2.4 MHz PWM; apply external clock (2.1–2.8 MHz) for EMI reduction. |
| GND (Pin 4) | Control ground reference | Reference for logic signals (EN, PS/SYNC, VSEL); must be tied to PGND at single point near thermal pad for stability. |
| VSEL (Pin 15) | Output voltage select | No effect in TPS630701 (fixed 5 V); left unconnected or grounded per datasheet guidance-no functional impact. |
| FB2 (Pin 6) | Secondary feedback node | Internally disabled in fixed-output variant; high-impedance when VSEL = low-no external connection required. |
| VAUX (Pin 3) | Auxiliary bias supply | Internal LDO output for gate drivers; requires 100 nF ceramic capacitor to GND-critical for startup and light-load stability. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic Buck-Boost Transition | Seamlessly switches between buck and boost topologies based on real-time VIN/VOUT ratio-no external control or mode pin needed. |
| Integrated Power Good (PG) | Open-drain PG output confirms regulation status with 94.5–98.5% VOUT threshold-enables safe processor boot sequencing and fault detection. |
| Low Quiescent Current | 54 µA typical in PFM mode-extends battery life in always-on applications like portable medical monitors and remote sensors. |
| Robust Protection Suite | Includes overtemperature shutdown (160 °C), input/output overvoltage lockout, short-circuit recovery via body diodes, and load disconnect during shutdown. |
| Thermally Optimized QFN | 2.5 mm × 3 mm VQFN with exposed thermal pad-supports >2 A continuous output with <63 °C/W junction-to-ambient thermal resistance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS630702RNMR | Same pinout and specs, but includes enabled output discharge (200 Ω internal FET) and adjustable output (2.5–9 V). | Suitable for systems requiring active VOUT discharge during shutdown (e.g., FPGA configuration retention, fast reset cycles). | Select TPS630702RNMR only if output discharge is explicitly required; otherwise TPS630701RNMR offers simpler fixed-5V implementation. |
| MP2451DT-LF-Z | Boost-only topology (2.5–24 V in, 5 V out), 2 A max, 1.5 MHz, no buck capability or PG output. | Limited to applications where VIN never exceeds VOUT (e.g., single Li-ion to 5 V); lacks seamless VIN/VOUT crossover support. | Choose MP2451DT-LF-Z only for cost-sensitive, VIN < VOUT-only use cases; TPS630701RNMR provides broader input flexibility and system-level monitoring. |
Compared with TPS630702RNMR, the TPS630701RNMR trades output discharge and voltage adjustability for simplified fixed-5V operation and reduced external component count. Against MP2451DT-LF-Z, it adds true buck-boost functionality, power-good signaling, and superior light-load efficiency-making it preferable for dynamically varying input sources.

FAQ
What is the output voltage setting of the TPS630701RNMR?
The TPS630701RNMR is factory-configured for a fixed 5.0 V output with ±1% dc accuracy in PWM mode and ±3%/−1% in PFM mode. Unlike the adjustable TPS63070 or TPS630702 variants, it requires no external feedback resistors-FB is internally tied to VOUT, and VSEL/FB2 are unused.
Does the TPS630701RNMR support automatic buck-to-boost transition?
Yes, the TPS630701RNMR automatically transitions between buck and boost modes based on real-time comparison of VIN and VOUT. When VIN drops below ~5.2 V (accounting for dropout), it seamlessly shifts to boost operation-ensuring uninterrupted 5-V output without external intervention or mode control pins.
What package type and thermal characteristics does the TPS630701RNMR have?
The TPS630701RNMR uses a 2.5 mm × 3 mm, 15-pin VQFN package (RNMR suffix) with exposed thermal pad. Its junction-to-ambient thermal resistance is 63 °C/W, and junction-to-board is 13 °C/W-enabling reliable 2 A operation with standard 2-layer PCB copper pours and proper thermal via placement under the pad.
Can the TPS630701RNMR be synchronized to an external clock?
Yes, the PS/SYNC pin of the TPS630701RNMR accepts an external clock signal between 2.1 MHz and 2.8 MHz to synchronize switching frequency. This reduces EMI peaks and enables deterministic timing in noise-sensitive applications such as audio subsystems or high-precision data acquisition.
Is output discharge supported on the TPS630701RNMR?
No, output discharge is disabled in the TPS630701RNMR. This distinguishes it from the TPS630702RNMR, which integrates a 200 Ω internal discharge FET. The TPS630701RNMR holds VOUT after shutdown-ideal for systems where residual output voltage must persist for state retention or controlled power-down sequences.
