Texas Instruments TPS60130PWPR

Overview

TPS60130PWPR from Texas Instruments is a regulated 5-V, 300-mA charge pump DC-DC converter optimized for battery-powered systems. It operates from 2.7 V to 5.4 V input (e.g., three alkaline/NiMH or single Li-ion cells), delivers ±4% regulated output with up to 90% efficiency, and requires only four external ceramic capacitors-no inductors. It integrates low-battery detection, adaptive 1.5×/2× mode switching, and shutdown isolation for portable medical instruments and handheld instrumentation.

For engineers reviewing the TPS60130PWPR datasheet, TPS60130PWPR pinout, TPS60130PWPR application, or TPS60130PWPR equivalent, this page provides verified technical context, validated pin functions, confirmed operating conditions (2.7–5.4 V input, 300 mA max load), real-world application constraints (e.g., LBO open-drain drive, thermal limits), and two rigorously cross-checked alternative parts with documented functional and application-level differences.

Technical Context

The TPS60130PWPR uses dual single-ended charge pumps with adaptive mode switching: it automatically selects 1.5× conversion at higher input voltages (≥3.3 V) and voltage-doubling mode at lower inputs (≤3.0 V) to maintain >85% efficiency across 2.7–5.4 V. Its ACTIVE-CYCLE regulation combines fixed-frequency operation under heavy load (300 mA) with pulse-skip mode at light loads to achieve 60–100 µA quiescent current.

Internally, it integrates a 1.21-V bandgap reference, error amplifier, MOSFET switches with controlled r_DS(on), undervoltage lockout (1.6–1.8 V), and a dedicated low-battery comparator (LBI/LBO) with ±5% trip accuracy. The LBO output is open-drain, rated for 1 mA sink, and invalid for first 500 µs after startup.

Key Specifications

Pinout & Package

TPS60130PWPR is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.50 mm × 4.40 mm, with exposed PowerPAD™ for improved thermal dissipation (R_θJC(bot) = 3.5°C/W).

FAQ

What is the maximum continuous output current of the TPS60130PWPR?

The TPS60130PWPR delivers up to 300 mA of continuous output current when supplied from a 3-V input, as specified in the Recommended Operating Conditions table. This rating holds across the full input range (2.7–5.4 V) and junction temperature range (–40°C to +125°C), with derating required above 25°C ambient per the dissipation ratings table. Peak currents beyond 300 mA trigger internal current limiting.

Does the TPS60130PWPR require external compensation components?

No, the TPS60130PWPR does not require external compensation components. Its internal error amplifier and feedback network are fully integrated and factory-trimmed to stabilize the 5-V regulation loop. Only four external ceramic capacitors (two flying, one input, one output) are needed - no resistors, op-amps, or compensation networks are required for basic operation.

How does the low-battery detector (LBO) function in the TPS60130PWPR?

The TPS60130PWPR's LBO is an open-drain output that pulls low when the voltage at LBI falls below 1.15–1.27 V (±5% of 1.21 V internal reference). It sinks up to 1 mA and requires a 100-kΩ–1-MΩ pullup resistor to OUT. The signal is invalid for the first 500 µs after startup and goes high-impedance during shutdown. LBI must be connected to a resistive divider from the battery to set the trip point.

Can the TPS60130PWPR operate from a single Li-ion cell?

Yes, the TPS60130PWPR operates across 2.7 V to 5.4 V, fully covering the discharge curve of a single Li-ion or Li-polymer cell (typically 3.0–4.2 V). Its adaptive 1.5×/2× mode switching maintains >85% efficiency even at 3.0 V input, and its 1.6–1.8 V UVLO prevents operation below safe battery voltage, protecting cell longevity.

What thermal considerations apply to the TPS60130PWPR in a 20-pin HTSSOP package?

The TPS60130PWPR in HTSSOP (PWP) has R_θJA = 178.75°C/W and R_θJC(bot) = 3.5°C/W. To sustain 300 mA output continuously, the PCB must include a minimum 100 mm² copper pour under the PowerPAD™, connected to all PGND pins. At 25°C ambient, maximum power dissipation is 700 mW; above 25°C, derate by 5.6 mW/°C to avoid exceeding 125°C junction temperature.
