Texas Instruments TPS60131PWPG4

Overview

TPS60131PWPG4 from Texas Instruments is a regulated 5-V ±4% charge pump DC-DC converter delivering up to 300 mA output current from a 2.7-V to 5.4-V input (e.g., three alkaline/NiMH cells or single Li-ion), featuring power-good detection, 60–100 µA quiescent current, and adaptive 1.5×/2× mode switching for >90% efficiency in battery-powered instrumentation.

For engineers reviewing the TPS60131PWPG4 datasheet, TPS60131PWPG4 pinout, TPS60131PWPG4 application, or TPS60131PWPG4 equivalent, key selection considerations include its HTSSOP-20 package with thermal PowerPAD™, open-drain PG output referenced to OUT, shutdown current of ≤1 µA, and compatibility with ceramic flying/output capacitors for low-EMI, inductorless 5-V generation in space-constrained portable systems.

Technical Context

The TPS60131PWPG4 implements dual single-ended charge pumps with automatic conversion-mode selection between 1.5× and voltage-doubler based on input voltage and load current-ensuring high efficiency across 2.7–5.4 V input range. Its internal 1.21-V bandgap reference and error amplifier regulate output via active-cycle control at heavy loads and pulse-skip mode at light loads.

It integrates a dedicated Power Good (PG) comparator with 0.86×VO to 0.94×VO trip threshold, open-drain PG output (sinks 1 mA), and requires no external resistive divider. Shutdown is controlled by ENABLE pin, disconnecting load and reducing supply current to ≤1 µA while maintaining <1 µA output leakage.

Key Specifications

FAQ

What is the function of the PG pin on the TPS60131PWPG4?

The PG (Power Good) pin on the TPS60131PWPG4 is an open-drain output that goes low when the regulated 5-V output falls below 0.86×VO, signaling loss of regulation. It requires a 100-kΩ to 1-MΩ pullup resistor to OUT and sinks up to 1 mA. This feature eliminates the need for external supervision circuitry and is used in systems like glucose meters to validate power integrity before initiating critical operations. The TPS60131PWPG4 does not require external resistors to set the trip point.

Does the TPS60131PWPG4 require external resistors for feedback or Power Good configuration?

No, the TPS60131PWPG4 does not require external resistors for feedback or Power Good configuration. Its FB pin connects directly to the OUT pin for internal regulation against a 1.21-V reference, and the PG comparator threshold (0.86×VO to 0.94×VO) is fixed internally. Unlike the TPS60130PWPG4's LBI input, the TPS60131PWPG4's PG function operates autonomously-only requiring an external pullup resistor to OUT for proper logic level translation.

Can the TPS60131PWPG4 operate from a single Li-ion battery?

Yes, the TPS60131PWPG4 operates from a single Li-ion or LiPo battery (nominal 3.6 V, range ~2.7–4.2 V), which falls fully within its 2.7-V to 5.4-V input specification. It delivers up to 300 mA at 5 V even at the 2.7-V minimum input, supporting full-load startup. This makes the TPS60131PWPG4 ideal for modern portable devices using single-cell lithium chemistry, including handheld medical instruments and compact test equipment.

How does the TPS60131PWPG4 achieve high efficiency without an inductor?

The TPS60131PWPG4 achieves up to 90% efficiency using a switched-capacitor (charge pump) topology with adaptive 1.5×/2× mode selection-dynamically choosing the optimal voltage multiplication ratio based on input voltage and load current. It employs low-R_DS(on) MOSFET switches, optimized gate drive, and internal control of charge/discharge time constants. Efficiency is sustained across 2.7–5.4 V input by minimizing conduction and switching losses without magnetic components.

What thermal considerations apply to the TPS60131PWPG4 in continuous 300-mA operation?

The TPS60131PWPG4 uses an HTSSOP-20 package with PowerPAD™ to achieve R_θJC(bot) = 3.5°C/W, enabling safe continuous 300-mA operation when the exposed die-pad is soldered to a large copper pour. Its R_θJA is 178.75°C/W in standard JEDEC layout; thermal design must include adequate PCB copper area under the PowerPAD™ and minimize ambient temperature rise. Derating begins above 25°C ambient-700 mW max power at 25°C, decreasing by 5.6 mW/°C.
