Product details
Overview
TPS60140PWPR from Texas Instruments is a regulated 5-V ±4% charge pump voltage tripler IC designed for low-power battery-powered systems. It delivers up to 100 mA output current from a 1.8 V–3.6 V input, features integrated low-battery detection (LBI/LBO), consumes only 65 µA quiescent current, and requires no inductors-enabling compact, low-EMI power conversion in portable medical instruments and smart card supplies.
For engineers reviewing the TPS60140PWPR datasheet, TPS60140PWPR pinout, TPS60140PWPR application, or TPS60140PWPR equivalent, this page provides verified technical context, validated pin functions, confirmed efficiency vs. load behavior, and real-world design constraints including capacitor selection rules, shutdown isolation, and LBI trip voltage adjustability.
Technical Context
The TPS60140PWPR uses an improved pulse-skip topology with active-cycle control to regulate output voltage: the error amplifier halts switching when VOUT ≥ 5 V and reactivates it upon droop, while dynamically controlling charge-pump output resistance to minimize ripple. This architecture achieves <40 mVPP ripple across 0–100 mA load range without inductors.
It integrates a precision 1.21 V reference, undervoltage lockout (UVLO) at 1.6 V, and a user-adjustable low-battery comparator (LBI input, LBO open-drain output). During shutdown (ENABLE = low), supply current drops to 0.05 µA and output is isolated from input via internal switch disconnect.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±4% (4.8–5.2 V); tightly regulated across 1.8–3.6 V input and 0–100 mA load |
| Max Output Current | 100 mA continuous; short-circuit limited to ~100 mA at VOUT = 0 V |
| Input Voltage Range | 1.8 V to 3.6 V; supports two alkaline/NiMH/NiCd cells with UVLO at 1.6 V |
| Quiescent Current | 65 µA typical at 2.4 V input; enables >1-year battery life in standby instrumentation |
| Shutdown Current | 0.05 µA max; isolates battery from load, preventing drain during storage |
| Oscillator Frequency | 210–450 kHz; variable frequency improves light-load efficiency and EMI profile |
| Output Ripple | <40 mVPP at 100 mA (COUT = 10 µF, X7R); reduced further with larger/low-ESR capacitors |
Pinout & Package
TPS60140PWPR is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.5 mm × 4.4 mm with exposed PowerPAD for improved thermal dissipation (RθJA = 42 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 7,14) | Power input | Battery or source connection; bypassed to PGND with 4.7 µF ceramic capacitor |
| OUT (Pin 5) | Regulated 5-V output | Supplies load; requires 10 µF ceramic output capacitor for ripple suppression |
| ENABLE (Pin 3) | Logic enable input | Active-high control; logic low disables converter and isolates output from input |
| FB (Pin 4) | Voltage feedback | Internally connected to 5 V output; ensures regulation by comparing to 1.21 V reference |
| LBI (Pin 18) | Low-battery input | Adjustable threshold input (1.15–1.27 V); used with external resistor divider to set warning voltage |
| LBO (Pin 17) | Low-battery output | Open-drain warning signal; requires 100 kΩ–1 MΩ pullup to OUT; invalid for first 500 µs after startup |
| C1+, C1− (Pins 6,8) | Flying capacitor terminals | Connect 2.2 µF ceramic capacitor (C1) to implement first charge-pump stage |
| C2+, C2− (Pins 15,13) | Flying capacitor terminals | Connect second 2.2 µF ceramic capacitor (C2) to complete voltage tripling path |
| PGND (Pins 9–12) | Power ground | High-current return path for charge-pump switching; must be short-traced to IN and CIN |
| GND (Pins 1,2,19,20) | Analog ground | Reference ground for internal comparators and error amplifier; connect to PGND near chip |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60141PWPR | Replaces LBI/LBO with power-good (PG) output; identical pinout, same 5 V/100 mA specs | Used where system requires confirmation of valid output voltage (e.g., FPGA configuration sequencing), not battery warning | Select TPS60141PWPR if power-good signaling is needed instead of low-battery detection |
| MAX680ESA+ | Unregulated 5 V output (±8%), 125 mA max, no LBI/PG, SO-8 package, higher IQ (120 µA) | Suitable for non-critical digital loads where regulation tolerance and battery monitoring are not required | Choose MAX680ESA+ only for cost-sensitive, non-regulated applications with relaxed ripple and no battery monitoring needs |
Compared with TPS60140PWPR, TPS60141PWPR offers identical performance but swaps low-battery warning for power-good signaling-making it ideal for sequenced power systems-while MAX680ESA+ trades regulation accuracy, battery monitoring, and quiescent current for lower cost and smaller package, limiting its use to less demanding digital rails.

FAQ
What is the regulated output voltage tolerance of the TPS60140PWPR?
The TPS60140PWPR delivers a tightly regulated 5.0 V output with ±4% tolerance (4.8 V to 5.2 V) across its full operating range: 1.8 V–3.6 V input voltage, –40°C to +85°C junction temperature, and 0–100 mA load current. This specification is guaranteed per TI's SLVS273A datasheet Section 8.5, Electrical Characteristics.
How does the TPS60140PWPR achieve low output voltage ripple without an inductor?
The TPS60140PWPR achieves low output ripple (<40 mVPP at 100 mA) through its active-cycle pulse-skip control architecture, which dynamically regulates the effective output resistance of the charge-pump stages. Combined with recommended 10 µF X7R/X5R ceramic output capacitance and low-ESR flying capacitors, this eliminates inductor-dependent ripple mechanisms while maintaining regulation.
Can the low-battery warning threshold of the TPS60140PWPR be adjusted, and how?
Yes-the TPS60140PWPR's LBI pin accepts an externally adjustable voltage divider. With R1 and R2 selected from the E96 series (e.g., 357 kΩ and 619 kΩ), the trip voltage ranges from 1.15 V to 1.27 V. The internal 1.21 V reference compares against the divided input; TI recommends total resistance between 100 kΩ and 1 MΩ to minimize leakage error.
What happens to the output during TPS60140PWPR shutdown mode?
When ENABLE is pulled low, the TPS60140PWPR enters shutdown mode: switching halts, supply current drops to ≤0.05 µA, and the output is actively disconnected from the input via internal MOSFET switches. Output leakage remains ≤1 µA, ensuring true battery isolation-critical for long-term storage in portable devices.
Which external capacitors are mandatory for basic TPS60140PWPR operation?
Four ceramic capacitors are mandatory: CIN = 4.7 µF (input bypass), C1 = C2 = 2.2 µF (flying capacitors), and COUT = 10 µF (output filter). All must be X5R or X7R dielectric types per TI's SLVS273A datasheet Section 8.5; Z5U/Y5V types are prohibited due to voltage/temperature capacitance loss.
