Product details
Overview
TPS60141PWPR from Texas Instruments is a regulated 5-V ±4% charge-pump voltage tripler IC for battery-powered systems, delivering up to 100 mA output current from a 1.8-V to 3.6-V input, featuring integrated power-good (PG) detection, 65-µA quiescent current, and shutdown isolation with 0.05-µA supply current - used in portable medical instruments and smart card supplies.
For engineers reviewing the TPS60141PWPR datasheet, TPS60141PWPR pinout, TPS60141PWPR application, or TPS60141PWPR equivalent, this page delivers verified electrical specs, HTSSOP-20 pin mapping, real-world load/line regulation behavior, and validated alternative options for low-noise, inductorless 5-V generation in space-constrained designs.
Technical Context
The TPS60141PWPR uses an improved pulse-skip topology that dynamically controls charge-pump output resistance to minimize output voltage ripple across 0–100 mA loads while maintaining regulation at ±4%. It integrates a precision 1.21-V internal reference and active-cycle control logic that disables switching and isolates input from output during light-load or shutdown conditions.
Its power-good (PG) output asserts low when VOUT falls below 90% of nominal (4.5 V), with 0.8% hysteresis, and operates as an open-drain signal requiring external pullup to OUT. The device supports undervoltage lockout at 1.6 V and short-circuit current limiting at 100 mA, with thermal protection enabled via its thermally enhanced HTSSOP package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±4% (4.8–5.2 V) - tightly regulated across full load and input range for stable 5-V rail generation |
| Max Output Current | 100 mA continuous - sufficient for microcontrollers, sensors, and smart card ICs powered from two alkaline/NiMH cells |
| Input Voltage Range | 1.8 V to 3.6 V - compatible with 2-cell battery stacks without under-voltage cutoff or brownout risk |
| Quiescent Current | 65 µA typical - enables >1-year battery life in always-on portable instrumentation |
| Shutdown Current | 0.05 µA max - isolates battery from load, preventing drain during storage or standby |
| Oscillator Frequency | 210–450 kHz - fixed-frequency switching optimized for ceramic capacitor compatibility and EMI control |
| Power-Good Threshold | 90% of VO (4.5 V typ.) with 0.8% hysteresis - provides reliable system reset or enable sequencing |
Pinout & Package
TPS60141PWPR is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.5 mm × 4.4 mm with exposed power pad for improved heat dissipation. Pin functions are validated per TI SLVS273A Rev. November 2015.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 7,14) | Supply input | Dual-input terminals for low-impedance connection to 1.8–3.6 V source; bypassed to PGND with 4.7 µF ceramic capacitor |
| OUT (Pin 5) | Regulated 5-V output | Main power rail; requires 10 µF ceramic output capacitor near load for <40 mVpp ripple at 100 mA |
| PG (Pin 17) | Power-good open-drain output | Asserts low when VOUT < 4.5 V; requires 100-kΩ–1-MΩ pullup to OUT for system monitoring or enable control |
| ENABLE (Pin 3) | Logic enable input | Active-high control: drives high ≥0.7×VIN to activate; pulls low to enter 0.05-µA shutdown with output isolation |
| FB (Pin 4) | Voltage feedback input | Internally referenced to 1.21 V; connects directly to OUT for fixed 5-V regulation (no external divider needed) |
| C1+, C1− (Pins 6,8) | Flying capacitor terminals | Drive first-stage charge pump; require 2.2 µF X5R/X7R ceramic capacitors with ESR < 0.1 Ω |
| C2+, C2− (Pins 15,13) | Flying capacitor terminals | Drive second-stage tripling; identical 2.2 µF ceramic capacitor requirement as C1 |
| PGND (Pins 9–12) | Power ground | High-current return path for charge-pump switching; must be short-traced and thermally coupled to PCB ground plane |
| GND (Pins 1,2,19,20) | Analog ground | Reference ground for error amplifier and reference; connected to PGND via short trace near IC |
| LBI/NC (Pin 18) | Low-battery input / no-connect | Not connected internally on TPS60141; must remain unconnected (not grounded) to avoid parasitic leakage paths |
| NC (Pin 16) | No-connect | Unused die bond pad; left floating per TI recommendation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge-pump voltage tripler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60140PWPR | Same HTSSOP-20 package and electrical specs, but includes low-battery indicator (LBI/LBO) instead of power-good (PG); LBI pin is functional, not NC | Used where battery voltage monitoring is required (e.g., handheld scanners), not where system-level power sequencing is critical | Select TPS60140PWPR only if low-battery warning functionality is needed; TPS60141PWPR is preferred for PG-driven reset or enable logic |
| MAX680ESA+ | Unregulated 5-V charge pump (±5% tolerance), 100 mA max, SO-8 package, no PG or shutdown control; 120 kHz oscillator | Suitable for non-critical digital logic rails where tight regulation and sequencing are unnecessary | Choose MAX680ESA+ only for cost-sensitive, non-regulated applications; lacks PG, shutdown isolation, and line/load regulation of TPS60141PWPR |
Compared with TPS60140PWPR, the TPS60141PWPR substitutes low-battery detection for power-good signaling - enabling precise system power sequencing rather than battery health monitoring. Against MAX680ESA+, it adds regulation, PG output, and shutdown isolation at the cost of package size and complexity.

FAQ
What is the function of the PG pin on the TPS60141PWPR?
The PG (power-good) pin on the TPS60141PWPR is an open-drain output that goes low when the regulated 5-V output falls below 90% of nominal (typically 4.5 V), with 0.8% hysteresis. It requires an external pullup resistor (100 kΩ to 1 MΩ) to OUT and is used for system reset assertion or enable sequencing. Unlike the TPS60140PWPR's LBO pin, PG is not present on the TPS60140 variant, and the TPS60141PWPR does not include LBI functionality.
Does the TPS60141PWPR require external feedback resistors to set the output voltage?
No, the TPS60141PWPR does not require external feedback resistors. Its FB pin is internally configured for fixed 5-V ±4% regulation using a 1.21-V reference; FB must be connected directly to the OUT pin near the load for optimal regulation. External dividers are unnecessary and would disrupt the factory-trimmed output accuracy - a key differentiator from adjustable-output charge pumps like the TPS60400 series.
How does the TPS60141PWPR achieve low output voltage ripple without an inductor?
The TPS60141PWPR achieves low output voltage ripple (<40 mVpp at 100 mA) through an improved pulse-skip topology that actively regulates charge-pump output resistance - reducing peak currents and minimizing ripple across the full load range. Combined with recommended 2.2 µF flying capacitors (X5R/X7R) and a 10 µF low-ESR output capacitor, this architecture delivers ripple performance comparable to linear regulators while maintaining >75% efficiency.
What is the maximum continuous output current specification for the TPS60141PWPR?
The TPS60141PWPR is specified for 100 mA maximum continuous output current under recommended operating conditions (1.8 V ≤ VIN ≤ 3.6 V, TJ ≤ 125°C). This rating is validated across temperature and input voltage, with short-circuit current limiting at ~100 mA to protect the device during output faults. Derating is not required up to 85°C ambient when using the HTSSOP-20 package with proper PCB copper area.
Can the TPS60141PWPR operate from a single 1.8-V alkaline cell?
No, the TPS60141PWPR cannot reliably operate from a single 1.8-V alkaline cell. Its minimum input voltage is 1.8 V, but practical operation requires ≥2.0 V to sustain 100 mA output due to internal losses and undervoltage lockout (UVLO) threshold of 1.6 V. It is designed for two-cell alkaline/NiMH/NiCd stacks (2.0–3.6 V nominal), where it maintains regulation even as cells discharge to 1.8 V per cell.
