Product details
Overview
TPS60141PWP 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 1.8–3.6 V input, featuring integrated power-good (PG) detection, 65 µA quiescent current, and 0.05 µA shutdown current - used in portable instruments and 5-V smart card supplies.
For engineers reviewing the TPS60141PWP datasheet, TPS60141PWP pinout, TPS60141PWP application, or TPS60141PWP equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application use cases, and two rigorously cross-checked alternative parts with functional and application-level distinctions.
Technical Context
The TPS60141PWP uses an improved pulse-skip topology that actively controls charge-pump output resistance to minimize output voltage ripple across the full 0–100 mA load range; regulation is achieved via internal 1.21 V reference and feedback loop tied to FB pin, with output stabilized by external 10 µF ceramic COUT and dual 2.2 µF flying capacitors (C1, C2).
It integrates a dedicated open-drain power-good (PG) output that asserts low when VOUT falls below 90% of nominal (i.e., <4.5 V), with hysteresis of 0.80%, and features undervoltage lockout (UVLO) at 1.6 V, enabling reliable start-up from weak alkaline/NiMH cells while isolating battery from load during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±4% (4.8–5.2 V) - maintains stable logic-level supply for 5-V microcontrollers and peripherals across full input and load range. |
| Max Output Current | 100 mA continuous - supports moderate-power analog/digital loads like LCD backlights or smart card interfaces without thermal derating. |
| Input Voltage Range | 1.8 V to 3.6 V - compatible with two-cell alkaline (2.0–3.2 V fresh), NiCd/NiMH (2.4 V nominal), or single Li-ion (3.0–3.6 V) sources. |
| Quiescent Current | 65 µA typical - enables >1-year battery life in always-on portable instrumentation with 200 mAh cells. |
| Shutdown Current | 0.05 µA max - ensures negligible battery drain during storage or standby, with true input-to-output isolation. |
| Oscillator Frequency | 210–450 kHz - balances EMI suppression and capacitor size; no inductor required, eliminating magnetic interference and PCB area. |
| Power-Good Threshold | 90% of VO (4.5 V typ.) with 0.80% hysteresis - provides clean, noise-immune system reset or supervisor signaling without external comparators. |
Pinout & Package
TPS60141PWP is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.5 mm × 4.4 mm with exposed PowerPAD for improved heat dissipation - suitable for compact, high-density battery-powered PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 7, 14) | Supply input | Dual-input terminals accept 1.8–3.6 V; bypassed to PGND with 4.7 µF ceramic capacitor to suppress input ripple and stabilize source impedance. |
| OUT (Pin 5) | Regulated 5-V output | Delivers up to 100 mA; requires 10 µF low-ESR ceramic capacitor to ground for ≤40 mVpp ripple under full load. |
| 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 reset generation or host monitoring. |
| ENABLE (Pin 3) | Logic enable input | Active-high control: drives high (>0.7×VIN) to operate, low (<0.3×VIN) to enter 0.05 µA shutdown with full input-output isolation. |
| FB (Pin 4) | Feedback input | Connects directly to OUT near load to close regulation loop; internal resistive divider references 1.21 V for precise 5-V output. |
| C1+, C1− (Pins 6, 8) | Flying capacitor terminals | Interface with 2.2 µF ceramic capacitor (C1) to implement first stage of voltage tripling; low-ESR critical for efficiency. |
| C2+, C2− (Pins 15, 13) | Flying capacitor terminals | Interface with second 2.2 µF ceramic capacitor (C2) to complete tripling path; must be placed adjacent to IC for minimal loop inductance. |
| PGND (Pins 9–12) | Power ground | High-current return path for charge-pump switching; must be short-traced and thermally connected to PowerPAD for thermal management. |
| GND (Pins 1, 2, 19, 20) | Analog ground | Reference for internal error amplifier and reference; connect to PGND via short, low-impedance trace to avoid noise coupling. |
| NC (Pin 16) | No connect | Internally unconnected; leave floating - no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| Regulated 5-V output with ±4% accuracy | Maintains tight tolerance across temperature (–40°C to +85°C) and line/load variations - eliminates need for post-regulation LDO in space-constrained designs. |
| Integrated power-good (PG) output | Provides system-level status flag with built-in hysteresis and open-drain drive - reduces BOM count by removing external supervisor ICs. |
| Inductorless charge-pump architecture | Enables ultra-low EMI operation and eliminates magnetic components - ideal for sensitive medical or RF-adjacent portable equipment. |
| 0.05 µA shutdown current with battery isolation | Prevents battery self-discharge during long-term storage - critical for backup-battery boost converters and shelf-life-sensitive devices. |
| Thermally enhanced HTSSOP (PWP) package | 42°C/W junction-to-ambient thermal resistance supports 100 mA continuous operation without heatsink in ambient ≤60°C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60131PWP | Outputs 3.3 V (not 5 V); same 100 mA rating, 65 µA IQ, and HTSSOP-20 package. | Suitable only where 3.3-V logic supply is required - not interchangeable for 5-V systems without redesign. | Select TPS60131PWP only if target application uses 3.3-V peripherals and cannot accommodate level-shifting. |
| MAX680ESA+ | Unregulated 5-V output (±8%); no PG output; 125 µA IQ; SO-8 package; requires 4 external caps but no FB pin. | Lacks regulation accuracy and power supervision - acceptable only for non-critical loads tolerant of wide voltage swing. | Choose MAX680ESA+ only for cost-sensitive, low-precision applications where 5-V ±8% and absence of PG are acceptable. |
Compared with TPS60141PWP, TPS60131PWP offers identical performance at 3.3 V but cannot replace it in 5-V systems, while MAX680ESA+ sacrifices regulation accuracy and supervision for lower cost and smaller footprint - making TPS60141PWP the sole choice for precision 5-V battery-powered applications requiring PG signaling.

FAQ
What is the regulated output voltage accuracy of the TPS60141PWP?
The TPS60141PWP delivers a regulated 5-V output with ±4% accuracy (4.8 V to 5.2 V) across the full operating temperature range (–40°C to +85°C), input voltage (1.8 V to 3.6 V), and load current (0–100 mA). This specification is guaranteed by internal 1.21 V reference and feedback loop - ensuring compatibility with standard 5-V logic and analog components without additional regulation.
Does the TPS60141PWP require external inductors?
No, the TPS60141PWP is an inductorless charge pump voltage tripler that uses only four external ceramic capacitors (two 2.2 µF flying caps, one 4.7 µF input cap, and one 10 µF output cap). Its architecture eliminates magnetic components, reducing EMI, PCB area, and BOM cost - a key advantage over traditional inductor-based boost converters.
How does the power-good (PG) function work on the TPS60141PWP?
The TPS60141PWP's PG pin is an open-drain output that pulls low when VOUT drops below 90% of nominal (typically 4.5 V), with 0.80% hysteresis. It requires an external 100 kΩ–1 MΩ pullup resistor to OUT. This signal enables reliable power sequencing and system reset - unlike the TPS60140's LBO, PG is active only when output is in regulation.
What is the shutdown current of the TPS60141PWP and how is isolation achieved?
The TPS60141PWP draws just 0.05 µA maximum in shutdown mode (ENABLE = low), and fully isolates the battery from the load by disconnecting internal switches. Output leakage remains ≤1 µA - enabling multi-year shelf life in backup-battery applications and eliminating parasitic drain in always-off portable devices.
Can the TPS60141PWP operate from a single Li-ion cell?
No - the TPS60141PWP requires minimum 1.8 V input, but its UVLO threshold is 1.6 V and recommended operating range starts at 1.8 V. A single Li-ion cell (2.7–4.2 V) exceeds the 3.6 V absolute maximum rating on IN. It is designed for two-cell alkaline/NiMH (2.0–3.2 V) or three-cell NiCd (3.0–3.6 V), not single Li-ion.
