Product details
Overview
TPS60131PWPR 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, featuring Power Good detection, 60-µA quiescent current, and operation in adaptive 1.5×/2× conversion modes. It serves as a compact, inductorless power supply for battery-powered microprocessor systems requiring stable 5-V rail generation from single Li-ion or triple alkaline/NiMH cells.
For engineers reviewing the TPS60131PWPR datasheet, TPS60131PWPR pinout, TPS60131PWPR application, or TPS60131PWPR equivalent, key selection criteria include its Power Good (PG) open-drain output functionality, HTSSOP-20 thermal performance (RθJA = 178.75°C/W), shutdown current of 0.05 µA, and compatibility with low-ESR ceramic flying/output capacitors in space-constrained portable instrumentation.
Technical Context
The TPS60131PWPR implements dual single-ended charge pumps with adaptive mode switching: it automatically selects between 1.5× and voltage-doubler (2×) conversion based on input voltage and load current to maintain >90% efficiency across 2.7–5.4 V input. Its internal 1.21-V bandgap reference and error amplifier regulate output via ACTIVE-CYCLE control-fixed-frequency at heavy loads, pulse-skip at light loads.
It integrates a dedicated Power Good comparator that asserts low when output falls below 0.9 × VO (4.5 V nominal), with 0.8% hysteresis and 1-mA sink capability. The ENABLE pin provides logic-level shutdown, disconnecting load from input and reducing supply current to 0.05 µA while maintaining <1-µA output leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±4% (4.8–5.2 V); tightly regulated across 0–300 mA load and 2.7–5.4 V input. |
| Max Output Current | 300 mA at 3-V input; enables direct powering of USB-peripheral interfaces or microcontroller I/O banks. |
| Input Voltage Range | 2.7 V to 5.4 V; supports single Li-ion (3.0–4.2 V), three alkaline/NiMH (3.6–4.5 V), or Lilon battery inputs. |
| Quiescent Current | 60–100 µA (no load); ensures minimal battery drain during standby in handheld medical devices. |
| Shutdown Current | 0.05 µA typical; isolates load and preserves battery life during system sleep modes. |
| Switching Frequency | 210–450 kHz (internal oscillator); enables use of small 1-µF ceramic flying capacitors without audible noise. |
| Power Good Threshold | 0.86–0.94 × VO; provides reliable system reset or supervisor signaling when 5-V rail drops below 4.3 V. |
Pinout & Package
TPS60131PWPR is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.50 mm × 4.40 mm, with exposed PowerPAD™ for improved heat dissipation (RθJC(bot) = 3.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENABLE (Pin 3) | Digital enable input | Logic-high (>0.7×VI) activates converter; logic-low disables all switching and disconnects load. |
| FB (Pin 4) | Feedback input | Internally connected to 1.21-V reference; requires direct connection to OUT near load for optimal regulation. |
| OUT (Pins 5, 16) | Regulated 5-V output | High-current output nodes; must be shorted together and bypassed with low-ESR ceramic capacitor. |
| LBO/PG (Pin 17) | Power Good open-drain output | Asserts low when VOUT < 4.5 V; requires external 100-kΩ–1-MΩ pullup to OUT for clean logic signaling. |
| LBI/NC (Pin 18) | No-connect (NC) on TPS60131 | Not internally bonded; must be left floating-unlike TPS60130/TPS60132 which use this pin for low-battery sense. |
| GND (Pins 1, 2, 19, 20) | Analog ground | Reference ground for feedback and control circuitry; separate from PGND to minimize noise coupling. |
| PGND (Pins 9–12) | Power ground | High-current return path for charge-pump switching; must be tied to GND with low-inductance layout. |
| C1+/C1−, C2+/C2− (Pins 6, 8, 13, 15) | Flying capacitor terminals | Four dedicated nodes for two external 1-µF ceramic flying caps; critical for charge transfer efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI and PCB area overhead; uses only four external ceramic capacitors for full 5-V conversion. |
| Adaptive 1.5×/2× mode switching | Maintains >90% efficiency across full input range by dynamically selecting optimal voltage gain ratio per load condition. |
| Power Good (PG) monitoring | Provides system-level fault indication with precise 4.5-V threshold and 0.8% hysteresis-enables safe processor reset sequencing. |
| Pulse-skip light-load regulation | Reduces quiescent current to 60 µA and eliminates switching noise during idle periods without sacrificing output stability. |
| Thermal-enhanced HTSSOP | PowerPAD™ design delivers RθJC(bot) = 3.5°C/W, enabling 300-mA operation in compact portable enclosures without forced airflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60130PWPR | Includes low-battery detector (LBO/LBI) instead of Power Good; identical 300-mA output and pinout. | Used where battery voltage monitoring is prioritized over output rail supervision (e.g., PDA main power). | Select TPS60130PWPR if system requires early warning of declining input voltage rather than 5-V rail integrity confirmation. |
| TPS60110PWP | Same 5-V/300-mA output but lacks Power Good and low-battery functions; higher quiescent current (120 µA typical). | Suitable for cost-sensitive, non-critical applications without system-level fault signaling requirements. | Choose TPS60110PWP only when PG functionality is unnecessary and board space allows larger input/output capacitance for ripple control. |
Compared with TPS60131PWPR, TPS60130PWPR offers identical power delivery but swaps PG for low-battery detection-making it unsuitable for rail-monitoring systems. TPS60110PWP omits both comparators and draws more quiescent current, limiting its use in long-life battery applications despite matching output specs.

FAQ
What is the primary function of the LBO/PG pin on the TPS60131PWPR?
The LBO/PG pin on the TPS60131PWPR is an open-drain Power Good output that pulls low when the regulated 5-V output falls below 4.5 V (0.9 × VO). It features 0.8% hysteresis and can sink up to 1 mA. An external 100-kΩ to 1-MΩ pullup resistor to OUT is required for proper logic-level signaling. This pin enables system-level power supervision and safe processor reset sequencing in applications like smart card readers and glucose meters.
Does the TPS60131PWPR require external inductors?
No, the TPS60131PWPR is a charge pump DC-DC converter and does not require any external inductors. It operates using only four external ceramic capacitors: two flying capacitors (C1, C2) and input/output filter capacitors. This inductorless architecture eliminates magnetic EMI, reduces PCB area, and simplifies layout-making the TPS60131PWPR ideal for compact, noise-sensitive portable instrumentation.
What is the maximum continuous output current specification for the TPS60131PWPR?
The TPS60131PWPR delivers up to 300 mA of continuous output current when supplied from a 3-V input, as specified in the datasheet's Recommended Operating Conditions and Electrical Characteristics tables. This rating applies across the full operating temperature range (–40°C to +125°C junction) and supports demanding loads such as microcontroller I/O banks or USB peripheral interfaces in handheld devices.
How does the TPS60131PWPR achieve high efficiency across a wide input voltage range?
The TPS60131PWPR achieves up to 90% efficiency across 2.7–5.4 V input by implementing adaptive mode switching: it automatically selects between 1.5× and 2× voltage conversion ratios based on real-time input voltage and load current. This dynamic selection optimizes charge transfer timing and minimizes switching losses-ensuring high efficiency whether powered by a single Li-ion cell (3.0–4.2 V) or three alkaline batteries (3.6–4.5 V).
What package type and thermal characteristics does the TPS60131PWPR use?
The TPS60131PWPR uses a 20-pin HTSSOP (PWP) package with PowerPAD™ thermal enhancement, measuring 6.50 mm × 4.40 mm. Its thermal metrics include RθJA = 178.75°C/W (junction-to-ambient) and RθJC(bot) = 3.5°C/W (junction-to-case bottom), enabling reliable 300-mA operation in compact, sealed enclosures without forced airflow-critical for handheld test equipment and portable medical devices.
