Product details
Overview
TPS60131PWPRG4 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, achieves up to 90% efficiency via adaptive 1.5×/2× mode switching, and requires only four external ceramic capacitors - no inductors. It is used in portable medical devices like glucose meters where compact size, low EMI, and stable 5-V rail generation are critical.
For engineers reviewing the TPS60131PWPRG4 datasheet, TPS60131PWPRG4 pinout, TPS60131PWPRG4 application, or TPS60131PWPRG4 equivalent, key selection criteria include its power-good detection capability, 0.05-µA shutdown current, 60–100-µA quiescent supply current, thermal performance in HTSSOP-20, and compatibility with space-constrained, low-noise battery-powered designs requiring precise 5-V regulation without magnetics.
Technical Context
The TPS60131PWPRG4 implements an adaptive dual-mode charge pump architecture: it automatically selects between 1.5× and voltage-doubler conversion based on input voltage and load current to maximize efficiency across 2.7–5.4 V. Its internal 1.21-V bandgap reference, error amplifier, and MOSFET switch control loop regulate output using active-cycle and pulse-skip modes - fixed-frequency at heavy loads, variable-frequency skip-mode at light loads.
Unlike fixed-ratio charge pumps, the TPS60131PWPRG4 integrates a dedicated open-drain Power Good (PG) comparator that asserts low when output falls below 0.86×VO (typ. 4.3 V) with 0.8% hysteresis. It features thermally enhanced HTSSOP-20 packaging with dedicated PGND pins (9,10,11,12) and dual IN/OUT power pins to reduce trace resistance and improve thermal dissipation (RθJA = 178.75°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±4% - tightly regulated rail suitable for USB-peripheral interfaces and logic-level translation without post-regulation. |
| Max Output Current | 300 mA at 3-V input - supports moderate-power microcontrollers, sensors, and display drivers in handheld instruments. |
| Input Voltage Range | 2.7 V to 5.4 V - covers full discharge range of 3× alkaline/NiMH or 1× Li-ion/LiPo batteries without external supervision. |
| Quiescent Current | 60–100 µA - enables >1-year standby in battery-backed medical or metering applications with infrequent wake-ups. |
| Shutdown Current | 0.05 µA (typ.) - isolates load from input and minimizes battery drain during deep sleep or system off-states. |
| Switching Frequency | 210–450 kHz - balances EMI suppression and capacitor size; avoids AM radio band and simplifies filtering. |
| Power Good Threshold | 0.86×VO to 0.94×VO (4.3–4.7 V) - provides reliable system reset or supervisor signaling before brownout occurs. |
Pinout & Package
TPS60131PWPRG4 is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.50 mm × 4.40 mm, with exposed thermal pad (PowerPAD™) for improved heat transfer to PCB copper. Pin 1 is marked by a dot; top-view orientation aligns with TI's standard PWP layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (7,14) | Supply input | Dual-input pins reduce trace impedance; must be shorted together and bypassed to PGND with ≥50% of CO capacitance. |
| OUT (5,16) | Regulated 5-V output | Dual-output pins lower IR drop; connect directly to load and bypass with low-ESR ceramic capacitor (CO). |
| ENABLE (3) | Logic-enable input | Active-high; VIH ≥0.7×VI ensures robust noise margin; ties to IN for always-on operation. |
| FB (4) | Feedback input | Internally referenced to 1.21 V; connect directly to OUT near load for best regulation accuracy and PSRR. |
| PG (17) | Power Good open-drain output | Asserts low when VO < 0.9×VO; requires 100-kΩ–1-MΩ pullup to OUT; high-impedance when disabled. |
| LBI/NC (18) | No-connect (NC) | Not internally connected on TPS60131; leave unconnected - distinct from LBI on TPS60130/TPS60132. |
| C1+, C1− (6,8), C2+, C2− (15,13) | Flying capacitor terminals | Four dedicated pins for two external ceramic flying caps (C1, C2); low-ESR ceramics mandatory for efficiency. |
| GND (1,2,19,20), PGND (9,10,11,12) | Analog & power ground | Separate GND (reference/control) and PGND (switching current return) minimize noise coupling into feedback path. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive 1.5×/2× conversion mode | Automatically selects optimal topology to sustain ≥85% efficiency from 2.7 V to 5.4 V input across 1–300 mA load. |
| Integrated Power Good (PG) comparator | Provides system-level fault signaling with 0.8% hysteresis - eliminates need for external supervisor IC in portable designs. |
| No-inductor architecture | Reduces EMI, board area, and BOM cost; enables ultra-thin profiles in PDAs, glucose meters, and smart cards. |
| Thermally enhanced HTSSOP-20 | PowerPAD™ exposes die attach pad to PCB copper; achieves 3.5°C/W junction-to-case (bottom) thermal resistance. |
| Pulse-skip light-load regulation | Halts switching when VO ≥5 V, reducing IQ to 60 µA and eliminating unnecessary switching losses during idle periods. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60130PWPR | Includes low-battery detector (LBO) instead of Power Good (PG); LBI input pin present; identical pinout and electrical specs otherwise. | Suitable where battery voltage monitoring is prioritized over output regulation status (e.g., battery gauging in PDAs). | Select TPS60130PWPR if system requires early warning of battery depletion; TPS60131PWPRG4 is preferred when output rail integrity is mission-critical. |
| TPS60110PWP | Delivers same 5-V/300-mA output but lacks PG/LBO comparators; uses simpler control architecture with fixed 2× mode only. | Used in cost-sensitive, non-supervised applications where external monitoring is already implemented. | Choose TPS60110PWP for lowest BOM cost where PG functionality is redundant; TPS60131PWPRG4 adds system-level reliability via integrated PG. |
Compared with TPS60130PWPR, the TPS60131PWPRG4 replaces low-battery detection with Power Good signaling - enabling tighter system-level power sequencing.

FAQ
What is the function of the PG pin on the TPS60131PWPRG4?
The PG (Power Good) pin on the TPS60131PWPRG4 is an open-drain output that signals when the regulated 5-V output is within specification. It pulls low when VO drops below 0.86×VO (≈4.3 V) and releases high when VO rises above 0.94×VO (≈4.7 V), with 0.8% hysteresis. The TPS60131PWPRG4 requires an external 100-kΩ to 1-MΩ pullup resistor to OUT; this pin is high-impedance during shutdown. It enables reliable system reset or supervisor handshaking without adding discrete components.
Does the TPS60131PWPRG4 require external resistors for feedback or regulation?
No, the TPS60131PWPRG4 does not require external feedback resistors. Its internal resistive divider is factory-trimmed to match a 1.21-V reference, and the FB pin is intended to be connected directly to the OUT pin near the load for optimal regulation. Unlike adjustable regulators, the TPS60131PWPRG4 is a fixed 5-V device - all regulation is handled internally, simplifying layout and eliminating resistor tolerance errors.
Can the TPS60131PWPRG4 operate from a single Li-ion cell?
Yes, the TPS60131PWPRG4 operates across 2.7 V to 5.4 V input, fully covering the discharge profile of a single Li-ion or LiPo cell (typically 4.2 V fully charged down to 2.8–3.0 V cutoff). At 3.0 V input, it delivers full 300-mA output current with ≥85% efficiency. Its undervoltage lockout (UVLO) disables operation below 1.6 V, preventing damage or erratic behavior during deep discharge - making the TPS60131PWPRG4 ideal for modern single-cell portable systems.
How does the TPS60131PWPRG4 achieve high efficiency without an inductor?
The TPS60131PWPRG4 achieves up to 90% efficiency using a switched-capacitor (charge pump) topology with adaptive 1.5× and 2× conversion modes. It dynamically selects the optimal ratio based on input voltage and load to minimize switching losses and conduction losses. Internal low-RDS(on) MOSFETs, optimized gate drive, and pulse-skip mode at light loads further reduce quiescent current. Because no magnetic components are needed, core losses and EMI from inductors are eliminated - a key advantage of the TPS60131PWPRG4 in noise-sensitive applications.
Is the TPS60131PWPRG4 pin-compatible with other devices in the TPS6013x family?
Yes, the TPS60131PWPRG4 shares identical 20-pin HTSSOP (PWP) packaging and pinout with TPS60130PWPR, TPS60132PWPR, and TPS60133PWPR. All variants use the same footprint, thermal pad, and signal assignments - enabling drop-in replacement for functional variants (e.g., swapping TPS60131PWPRG4 for TPS60130PWPR requires only updating LBI/PG routing). However, LBI (pin 18) is NC on TPS60131PWPRG4, and PG (pin 17) replaces LBO functionality - PCB design must reflect this functional difference.
