Product details
Overview
TPS61030PWPRG4 from Texas Instruments is a synchronous boost DC-DC converter IC designed for single-cell Li-ion or dual/triple-cell alkaline/NiMH battery-powered systems. It delivers up to 1000 mA at 5 V from 1.8–5.5 V input, features 96% peak efficiency, 600 kHz fixed-frequency PWM control, and integrated low-battery comparator with 500 mV threshold on LBI pin - used in portable audio players and PDAs.
For engineers reviewing the TPS61030PWPRG4 datasheet, TPS61030PWPRG4 pinout, TPS61030PWPRG4 application, or TPS61030PWPRG4 equivalent, key selection considerations include its 4 A switch current limit, Power Save mode for light-load efficiency, load disconnect during shutdown, low-EMI antiringing switch, and compatibility with 4 mm × 4 mm QFN-16 (PWP) layout.
Technical Context
The TPS61030PWPRG4 implements a fixed-frequency, multiple feedforward PWM controller that monitors input voltage, output voltage, and NMOS switch voltage drop to directly adjust duty cycle-bypassing slow error-amplifier loop for fast transient response. Its synchronous rectifier uses integrated N-channel and P-channel MOSFETs with separate PGND and GND pins to minimize ground shift and enable true load isolation.
It supports three operational modes via the SYNC pin: Power Save mode (SYNC = GND), fixed-frequency mode (SYNC = VBAT), or external clock synchronization (500–700 kHz). The low-battery detector activates only when EN = high, compares scaled battery voltage against an internal 500 mV reference with 10 mV hysteresis, and drives open-drain LBO low upon threshold breach.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 5.5 V - supports one-cell Li-ion (2.5–4.2 V) and two/three-cell alkaline/NiMH (1.8–5.5 V) without external regulation. |
| Output Current | Up to 1000 mA at 5 V - enables powering USB-peripheral-level loads from low-voltage batteries. |
| Switch Current Limit | 4000 mA typical - limits peak inductor current to prevent saturation and thermal overload under heavy load or startup. |
| Feedback Reference Voltage | 500 mV ±10 mV - sets adjustable output voltage via external resistor divider (e.g., 5 V with R3=180 kΩ, R4=200 kΩ). |
| Quiescent Current | 20 µA typical - ensures minimal battery drain in active operation, critical for always-on portable devices. |
| Shutdown Current | 0.1–1 µA - achieves true battery isolation; no external load-switch FET required for zero-current standby. |
| Oscillator Frequency | 600 kHz nominal - balances EMI, inductor size, and efficiency; synchronizable to external clock within ±20% range. |
Pinout & Package
TPS61030PWPRG4 is housed in a thermally enhanced 4 mm × 4 mm QFN-16 package (PWP) with exposed PowerPAD™ soldered to PGND for optimal thermal dissipation. Pin 1 is SW (boost switch node); pin 11 is GND (control ground); pin 3/4/5 are PGND (power ground); pin 16 is NC (no internal connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2) | Boost switch node | Connects to inductor and diodeless synchronous rectifier; carries high di/dt switching current - requires short, low-inductance routing. |
| PGND (3,4,5) | Power ground return | Low-impedance path for switch and rectifier currents; must be tied to PowerPAD™ and connected to GND at single point near GND pin. |
| VBAT (6) | Main power input | Accepts 1.8–5.5 V battery source; feeds internal regulator and switch driver - bypass capacitor mandatory. |
| LBI (7) | Low-battery comparator input | High-impedance analog input (0.01 µA bias); accepts scaled battery voltage - resistor divider sets detection threshold (e.g., 3.0 V → 500 mV). |
| SYNC (8) | Mode control / sync input | Digital input selecting Power Save (low), fixed-frequency (high), or external clock (500–700 kHz square wave). |
| EN (9) | Enable control | Active-high logic input; pulls device into full shutdown (load disconnected, all circuitry off) when low. |
| LBO (10) | Low-battery output | Open-drain flag - sinks current when LBI voltage falls below 500 mV; requires external pullup to VOUT or system rail. |
| FB (12) | Voltage feedback | Monitors output via resistor divider; regulates output by maintaining 500 mV at this pin - sets accuracy and load/line regulation. |
| GND (11) | Control ground reference | Reference for all logic, error amplifier, and comparator circuits - must be star-connected to PGND at single point. |
| VOUT (13,14,15) | Regulated output | Delivers stable boosted voltage (adjustable up to 5.5 V); multiple pins reduce IR drop and improve current handling. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated N- and P-MOSFETs replace Schottky diode - eliminates forward voltage drop, enabling 96% peak efficiency and reducing thermal load. |
| Load disconnect during shutdown | Special backgate disconnection circuit isolates VOUT from VBAT when EN = low - prevents battery drain without external MOSFET. |
| Integrated antiringing switch | Clamps SW node to VBAT during discontinuous conduction mode - suppresses high-frequency ringing and reduces radiated EMI by >10 dB. |
| Power Save mode | Operates in burst mode at light load (e.g., <10 mA) - maintains >85% efficiency down to 100 µA output while keeping quiescent current at 20 µA. |
| Undervoltage lockout (UVLO) | Disables startup if VBAT < ~1.6 V - prevents erratic operation and protects battery from deep discharge damage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61032PWPR | Adjustable output version (same package, same specs); differs only in internal feedback network - TPS61030 has fixed 3.3 V output, TPS61032 is fully adjustable. | Used where output voltage must be set externally (e.g., 5 V, 3.6 V) rather than fixed 3.3 V; requires FB resistor divider. | Select TPS61032PWPR if output voltage flexibility is needed; TPS61030PWPRG4 is optimal for cost-sensitive 3.3 V-only designs. |
| TPS61291DRVR | Lower IQ (1.3 µA), smaller 2 mm × 2 mm WSON-6 package, but lower 1.2 A switch limit and 5.5 V max output - no LBI/LBO or SYNC pin. | Suitable for space-constrained, ultra-low-power IoT sensors; lacks battery monitoring and synchronization capability. | Choose TPS61291DRVR only for minimal-footprint, sub-100 µA standby applications; TPS61030PWPRG4 remains preferred for feature-rich portable power. |
Compared with TPS61032PWPR, TPS61030PWPRG4 offers plug-and-play 3.3 V regulation without external resistors; compared with TPS61291DRVR, it provides full battery supervision, synchronization, and higher output current - making it the balanced choice for mid-complexity portable systems.

FAQ
What is the output voltage configuration of the TPS61030PWPRG4?
The TPS61030PWPRG4 is a fixed-output 3.3 V boost converter. Unlike adjustable variants such as TPS61032, it does not require external feedback resistors - the 3.3 V regulation is implemented internally using a precision voltage divider. This simplifies PCB layout and reduces BOM count for applications where 3.3 V is the target rail. The TPS61030PWPRG4 maintains ±3% total output accuracy over temperature and load variations.
Does the TPS61030PWPRG4 support load disconnect during shutdown?
Yes, the TPS61030PWPRG4 actively disconnects the load from the battery during shutdown. When the EN pin is pulled low, internal circuitry isolates the VOUT pins from VBAT by disconnecting the cathode of the high-side PMOS backgate diode - preventing reverse current flow through the body diode. This feature eliminates the need for an external load switch and ensures zero standby current draw from the battery, which is critical for long shelf-life portable devices.
How does the low-battery detection work on the TPS61030PWPRG4?
The TPS61030PWPRG4 implements a dedicated low-battery comparator with input on LBI and open-drain output on LBO. When enabled (EN = high), it compares the voltage at LBI to an internal 500 mV reference. A resistor divider from VBAT to GND sets the trip point (e.g., 3.0 V → 500 mV). LBO pulls low when the threshold is crossed, signaling battery depletion to the host MCU. The LBI pin includes 10 mV hysteresis to prevent chatter during gradual discharge.
Can the TPS61030PWPRG4 be synchronized to an external clock?
Yes, the TPS61030PWPRG4 supports external clock synchronization via the SYNC pin. Applying a square-wave signal with 30–70% duty cycle and frequency between 500 kHz and 700 kHz forces the internal oscillator to lock to that frequency. This capability enables EMI reduction by aligning switching noise to a known frequency band and facilitates multi-rail power sequencing in complex systems. When SYNC is left unconnected or pulled high, the device operates in fixed-frequency mode at ~600 kHz.
What thermal considerations apply to the TPS61030PWPRG4 in QFN-16 (PWP) package?
The TPS61030PWPRG4 in the 4 mm × 4 mm QFN-16 (PWP) package requires proper thermal design: the exposed PowerPAD™ must be soldered to a large PGND copper area (≥100 mm² recommended) to achieve the specified RθJA of 46.9°C/W. Thermal vias under the pad (6–8 x 0.3 mm) connecting to inner ground planes significantly improve heat dissipation. Junction temperature must remain ≤125°C under maximum load; derating is advised above 85°C ambient due to reduced switch current limit and efficiency.
