Product details
Overview
TPS60140PWPRG4 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 low-battery warning (LBI/LBO), 65 µA quiescent current, and shutdown isolation with 0.05 µA supply current - used in two-cell alkaline/NiMH portable instruments and smart card supplies.
For engineers reviewing the TPS60140PWPRG4 datasheet, TPS60140PWPRG4 pinout, TPS60140PWPRG4 application, or TPS60140PWPRG4 equivalent, key selection criteria include input voltage range compatibility (1.8–3.6 V), regulated 5-V output tolerance (±4%), low-battery comparator adjustability, thermal performance in HTSSOP-20 (RθJA = 42 °C/W), and capacitor-based design eliminating inductors.
Technical Context
The TPS60140PWPRG4 implements 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. It uses dual flying capacitors (C1, C2) and internal voltage reference (1.21 V) to regulate output via feedback at the FB pin.
Startup includes precharge limiting to 0.8 × VIN before switching activation, while shutdown disconnects OUT from IN and reduces supply current to 0.05 µA. The LBI comparator (trip: 1.15–1.27 V) drives open-drain LBO with 1 mA sink capability and 500 µs startup invalidation period.
Key Specifications

| Max Output Current | 100 mA continuous (minimum guaranteed at VIN = 2.0 V) |
| Input Voltage Range | 1.8 V to 3.6 V (UVLO disables below 1.6 V) |
| Quiescent Current | 65 µA typical (no-load, VIN = 2.4 V) |
| Shutdown Current | 0.05 µA typical (output isolated from input) |
| Oscillator Frequency | 210–450 kHz (input-voltage dependent, no external timing component) |
| Low-Battery Trip | 1.21 V ±5% internal reference; user-adjustable via resistive divider on LBI |
| Thermal Resistance | RθJA = 42 °C/W (HTSSOP-20 package, JEDEC standard board) |
Pinout & Package
TPS60140PWPRG4 is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.5 mm × 4.4 mm with exposed power pad for PGND connection and optimized thermal dissipation (RθJC(bot) = 1.6 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 7, 14) | Supply input | Battery or source input (1.8–3.6 V); bypassed to PGND with 4.7 µF ceramic capacitor |
| OUT (Pin 5) | Regulated output | 5-V ±4% power rail; requires 10 µF ceramic output capacitor for ripple control |
| FB (Pin 4) | Voltage feedback | Connects directly to OUT near load to maintain regulation accuracy against trace IR drop |
| ENABLE (Pin 3) | Logic enable | Active-high control; logic low disables converter and isolates OUT from IN |
| LBI (Pin 18) | Low-battery input | Compares external voltage to 1.21 V reference; adjustable trip via resistor divider |
| LBO (Pin 17) | Low-battery output | Open-drain warning signal; requires 100 kΩ–1 MΩ pullup to OUT |
| C1+, C1− (Pins 6, 8) | Flying capacitor terminals | Drive first-stage charge transfer; require 2.2 µF X5R/X7R ceramic capacitors |
| C2+, C2− (Pins 15, 13) | Flying capacitor terminals | Drive second-stage voltage tripling; same capacitor requirements as C1 |
| PGND (Pins 9–12) | Power ground | High-current return path for charge pump switches; must be short-traced to exposed pad |
| GND (Pins 1, 2, 19, 20) | Analog ground | Reference ground for error amplifier and comparators; connect to PGND via short trace |
| NC (Pin 16) | No connect | Internally unconnected; leave floating |
Key Features
| Feature | Design Value |
|---|---|
| Inductorless architecture | Eliminates EMI-sensitive magnetics and simplifies layout using only four ceramic capacitors |
| Active-cycle pulse-skip control | Dynamically adjusts charge-pump output resistance to reduce ripple at light loads without increasing quiescent current |
| Integrated low-battery detector | User-programmable threshold (1.15–1.27 V) with open-drain LBO output for system-level battery monitoring |
| Output isolation in shutdown | 0.05 µA shutdown current and <1 µA output leakage ensure battery preservation during standby |
| Robust start-up sequencing | Precharges output to 0.8 × VIN before enabling switching, limiting inrush into empty COUT |
| Short-circuit protection | Current-limited to ~100 mA during hard output shorts, preventing damage and thermal runaway |

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 and electrical specs except comparator function | Used where system requires output-valid indication instead of battery-low warning | Select TPS60141PWPR when power-good signaling (90% VOUT threshold) is needed over low-battery detection |
| MAX680ESA+ | Unregulated 5-V charge pump; no feedback, no LBI/PG, higher quiescent current (120 µA), SO-8 package | Suitable only for non-critical loads tolerant of ±10% output variation | Choose MAX680ESA+ only for cost-sensitive, low-precision applications where regulation and battery monitoring are unnecessary |
Compared with TPS60140PWPRG4, TPS60141PWPR offers identical efficiency and thermal performance but swaps low-battery alert for power-good status, while MAX680ESA+ sacrifices regulation accuracy and quiescent current for lower cost and smaller footprint - making TPS60140PWPRG4 optimal for precision, battery-aware portable designs.

FAQ
What is the input voltage range supported by the TPS60140PWPRG4?
The TPS60140PWPRG4 supports an input voltage range of 1.8 V to 3.6 V. Operation below 1.6 V triggers undervoltage lockout (UVLO), disabling the device. This range is optimized for two-cell alkaline, NiCd, or NiMH batteries across their full discharge profile, ensuring reliable 5-V output even as cell voltage declines.
How does the low-battery detection function work on the TPS60140PWPRG4?
The TPS60140PWPRG4 features an internal 1.21 V reference comparator connected to the LBI pin. When the voltage applied to LBI falls below 1.15–1.27 V (adjustable via external resistor divider), the open-drain LBO pin pulls low. LBO requires a 100 kΩ–1 MΩ pullup resistor and remains invalid for the first 500 µs after startup.
Can the TPS60140PWPRG4 operate without external capacitors?
No - the TPS60140PWPRG4 requires four external ceramic capacitors: two 2.2 µF flying capacitors (C1, C2), one 4.7 µF input capacitor (CIN), and one 10 µF output capacitor (COUT). These are essential for charge transfer, input filtering, and output regulation; omitting any prevents proper voltage tripling and regulation.
What is the maximum continuous output current of the TPS60140PWPRG4?
The TPS60140PWPRG4 delivers up to 100 mA continuous output current while maintaining 5-V ±4% regulation. This is guaranteed at VIN ≥ 2.0 V and ambient temperatures from –40°C to 85°C. Short-circuit current is internally limited to ~100 mA to protect the device during fault conditions.
Does the TPS60140PWPRG4 require an inductor in its circuit design?
No - the TPS60140PWPRG4 is an inductorless charge pump IC. It uses switched-capacitor topology with two external flying capacitors (C1, C2) to triple the input voltage, eliminating magnetic components, reducing EMI, and enabling ultra-compact PCB layouts ideal for portable and space-constrained applications.
