Product details
Overview
TPS61030PWP 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-V input, features 96% peak efficiency, 600-kHz fixed-frequency PWM control, and integrated low-battery comparator with 500-mV threshold on LBI pin.
For engineers reviewing the TPS61030PWP datasheet, TPS61030PWP pinout, TPS61030PWP application, or TPS61030PWP equivalent, key selection considerations include its 4-A switch current limit, Power Save mode operation, load disconnect during shutdown, thermal protection, and compatibility with 4 mm × 4 mm QFN-16 (PWP) layout.
Technical Context
The TPS61030PWP 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 dynamics for fast transient response. Peak current sensing limits switch current to 4000 mA typical, while internal temperature sensing triggers overtemperature shutdown at 140°C.
It integrates a synchronous rectifier using N-channel and P-channel MOSFETs, eliminating external Schottky diodes and enabling 96% efficiency. Dual ground paths (GND for logic, PGND for power) isolate high-current switching noise; load disconnection during shutdown is achieved by actively isolating the PMOS backgate diode cathode when EN = low.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Output Current | Up to 1000 mA at 5 V - sufficient for USB-peripheral rail or display backlight in portable devices |
| Switch Current Limit | 4000 mA typical - enables robust startup into heavy capacitive loads and short-circuit tolerance |
| Feedback Voltage | 500 mV ±10 mV - sets adjustable output via resistor divider; supports 1.8–5.5 V range |
| Quiescent Current | 20 µA typical - maintains ultra-low standby drain in battery-critical applications |
| Shutdown Current | 0.1–1 µA - ensures minimal battery depletion during system sleep or off-state |
| Oscillator Frequency | 600 kHz nominal - balances EMI, inductor size, and efficiency for compact portable designs |
| Thermal Shutdown | 140°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design |
Pinout & Package
TPS61030PWP is housed in a thermally enhanced 4 mm × 4 mm QFN-16 package (PWP) with exposed PowerPAD™ soldered to PGND for optimal heat dissipation. The package requires PCB thermal vias under the PowerPAD™ to achieve RθJB = 12.9°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW (1,2) | Boost switch node | Connects to inductor and catch diode path; carries high di/dt switching current; requires tight layout and low-inductance routing |
| VBAT (6) | Main power input | Accepts 1.8–5.5 V battery source; feeds internal regulator and power switches |
| VOUT (13,14,15) | Regulated output | Delivers stable boosted voltage; multiple pins reduce IR drop and improve current sharing |
| FB (12) | Feedback input | Senses output via resistor divider; 500-mV reference enables precise adjustable output voltage setting |
| EN (9) | Enable control | Active-high logic input; disables all circuitry and disconnects load from battery when low |
| LBI (7) | Low-battery comparator input | Accepts scaled battery voltage; compares to 500-mV internal reference to trigger LBO |
| LBO (10) | Low-battery open-drain output | Drives low when LBI < 500 mV; requires external pull-up for system-level battery alert signaling |
| SYNC (8) | Power Save / sync control | Low = enable Power Save mode; high = fixed-frequency operation; external clock input for synchronization |
| GND (11) | Logic ground reference | Reference for all control circuits; must be connected near PowerPAD™ to minimize noise coupling |
| PGND (3,4,5) | Power ground return | Return path for high-current SW and VOUT paths; separate from GND to avoid ground bounce |
| NC (16) | No internal connection | Unbonded pad; must remain unconnected on PCB |
| PowerPAD™ | Thermal & electrical ground | Exposed die attach pad; must be soldered to large PGND copper area with ≥6 thermal vias |

FAQ
What is the maximum output voltage supported by the TPS61030PWP?
The TPS61030PWP supports an adjustable output voltage range of 1.8 V to 5.5 V, set via external resistor divider on the FB pin. Its internal feedback reference is 500 mV ±10 mV, and the maximum rated output voltage is 5.5 V per absolute maximum ratings. Operation above 5.5 V risks damage and violates SOA limits.
Does the TPS61030PWP require external components for basic operation?
Yes, the TPS61030PWP requires an external inductor (typically 6.8 µH), input capacitor (10 µF ceramic), output capacitor (2.2 µF ceramic + 220 µF tantalum), and two feedback resistors (R3/R4) to set output voltage. The LBI/LBO circuit also needs two resistors (R1/R2) if low-battery detection is used. No external compensation is needed due to internal compensation.
How does the TPS61030PWP handle thermal overload?
The TPS61030PWP incorporates overtemperature protection that shuts down the device when junction temperature reaches 140°C. It remains latched off until temperature drops by 20°C hysteresis (to ~120°C), then automatically resumes operation. This protects against sustained overload, poor PCB thermal design, or ambient temperature excursions without requiring external thermal sensors.
Can the TPS61030PWP be synchronized to an external clock?
Yes, the TPS61030PWP supports external synchronization via the SYNC pin. Applying a clock signal with 30–70% duty cycle and frequency within ±20% of 600 kHz (i.e., 480–720 kHz) forces the converter to operate at that frequency. This reduces beat frequencies in multi-rail systems and simplifies EMI filtering by fixing the fundamental switching frequency.
What is the purpose of the separate GND and PGND pins on the TPS61030PWP?
The TPS61030PWP uses separate GND (pin 11) for logic/reference ground and PGND (pins 3,4,5) for high-current power return to minimize noise coupling. GND serves as the reference for FB, EN, SYNC, and LBI/LBO; PGND carries peak inductor and switch currents. Both must connect to the same system ground plane-but only at a single point near the PowerPAD™-to prevent ground loops and switching noise injection into control circuits.
