Product details
Overview
TPS60132PWP from Texas Instruments is a regulated 5-V, 150-mA charge pump DC-DC converter in HTSSOP-20 package, designed for space-constrained battery-powered systems. It operates from 2.7 V to 5.4 V input (e.g., three alkaline/NiMH or single Li-ion cells), delivers ±4% regulated output with up to 90% efficiency, and features low-battery detection via LBI/LBO pins.
For engineers reviewing the TPS60132PWP datasheet, TPS60132PWP pinout, TPS60132PWP application, or TPS60132PWP equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative options, and supply-chain support details specific to TPS60132PWP - not the broader TPS6013x family.
Technical Context
The TPS60132PWP implements adaptive mode switching between 1.5× and voltage-doubler conversion to maintain high efficiency across its 2.7–5.4 V input range and 0–150 mA load. Its internal 1.21-V bandgap reference and error amplifier enable ACTIVE-CYCLE regulation: fixed-frequency operation at heavy loads and pulse-skip mode at light loads to minimize quiescent current (60–100 µA).
It integrates a low-battery detector with programmable trip threshold (1.15–1.27 V at LBI), open-drain LBO output, undervoltage lockout (1.6–1.8 V), and thermal shutdown. All power switches are MOSFET-based; no inductors are required, and only four external ceramic capacitors are needed for full operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 5 V ±4% (4.8–5.25 V) - stable rail for USB-peripheral, microcontroller I/O, or analog circuitry without external feedback resistors. |
| Max output current | 150 mA at 3 V input - sufficient for low-power MCU cores, sensors, and interface ICs in portable instrumentation. |
| Input voltage range | 2.7 V to 5.4 V - supports 3-cell alkaline/NiMH (fully discharged to 0.9 V/cell) and single Li-ion (3.0–4.2 V). |
| Quiescent current | 60–100 µA - enables >1-year battery life in always-on monitoring devices powered by two AA cells. |
| Shutdown current | 0.05 µA max - isolates load from source and preserves battery during storage or sleep modes. |
| Switching frequency | 210–450 kHz - allows use of small 1–2.2 µF ceramic flying capacitors and minimizes EMI vs. lower-frequency alternatives. |
| Efficiency | Up to 90% - reduces thermal load in sealed enclosures and extends runtime in handheld medical meters. |
Pinout & Package
TPS60132PWP uses a thermally enhanced 20-pin HTSSOP (PWP) package (6.50 mm × 4.40 mm), with exposed PowerPAD™ for improved heat dissipation (RθJC(bot) = 3.5°C/W). GND and PGND pins are separated to isolate analog reference ground from high-current charge-pump return paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 7, 14) | Power input | Dual-pin configuration lowers impedance; requires local 4.7–10 µF ceramic bypass to PGND to stabilize input current. |
| OUT (Pins 5, 16) | Regulated 5-V output | Dual-pin layout reduces IR drop; connects directly to load and output capacitor (10–47 µF ceramic) near device. |
| GND (Pins 1, 2, 19, 20) | Analog ground | Reference ground for FB, LBI, and internal bandgap; must be short-traced to PGND only at single point near PowerPAD™. |
| PGND (Pins 9–12) | Power ground | High-current return path for flying capacitors; connects directly to PowerPAD™ and output capacitor negative terminal. |
| ENABLE (Pin 3) | Enable control | Active-high logic input; tie to IN for always-on operation; drives <0.05 µA shutdown current when pulled low. |
| FB (Pin 4) | Feedback input | Internally referenced to 1.21 V; connect directly to OUT near load to compensate for PCB trace resistance. |
| LBI (Pin 18) | Low-battery input | Connects to resistor divider from battery; trips comparator at 1.21 V ±5%; leave grounded if unused. |
| LBO (Pin 17) | Low-battery output | Open-drain alert signal; requires 100 kΩ–1 MΩ pullup to OUT; invalid for first 500 µs after startup. |
| C1+, C1− (Pins 6, 8) C2+, C2− (Pins 15, 13) |
Flying capacitor terminals | Four dedicated pins for two 1–2.2 µF ceramic flying caps; layout symmetry critical for balanced charge transfer. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60130PWP | Same package and pinout; rated for 300 mA output (vs. 150 mA); includes identical low-battery detector. | Supports higher-current peripherals (e.g., motor drivers, larger displays); requires larger output capacitor and thermal margin. | Select TPS60130PWP only if sustained >150 mA load is required; otherwise TPS60132PWP offers better light-load efficiency and smaller BOM. |
| MAX680ESA+ | SO-8 package; fixed 5-V output; no low-battery detection; 100 mA max output; 120 kHz switching. | Suitable for space-tolerant designs where battery monitoring is handled externally; lower cost but higher EMI and lower efficiency (75%). | Choose MAX680ESA+ only for legacy SO-8 layouts or cost-sensitive consumer products without battery telemetry needs. |
Compared with TPS60130PWP and MAX680ESA+, the TPS60132PWP uniquely balances 150 mA capability, integrated low-battery alert, HTSSOP thermal performance, and 90% peak efficiency - making it optimal for next-generation portable medical and industrial handhelds requiring both runtime and diagnostics.

FAQ
What is the maximum continuous output current of the TPS60132PWP?
The TPS60132PWP delivers up to 150 mA continuous output current when supplied from a 3-V input, as specified in the Recommended Operating Conditions table. At inputs below 3 V, output current derates linearly to maintain regulation; at 2.7 V, maximum load is ~120 mA. This rating assumes proper thermal management using the PowerPAD™ and adequate PCB copper area per TI's thermal guidelines.
Does the TPS60132PWP require external feedback resistors to regulate its 5-V output?
No, the TPS60132PWP does not require external feedback resistors. Its internal resistive divider and 1.21-V bandgap reference set the output to 5 V ±4%. The FB pin is internally connected to this divider; connecting FB directly to the OUT pin (as recommended) closes the loop without external components - simplifying layout and improving regulation accuracy.
How does the low-battery detection function work on the TPS60132PWP?
The TPS60132PWP includes a dedicated low-battery detector with LBI (input) and LBO (open-drain output) pins. The internal comparator trips when the voltage at LBI falls to 1.21 V ±5%. Users program the battery trip point using an external resistor divider from the battery to ground. LBO pulls low to signal low battery and requires a 100-kΩ to 1-MΩ pullup resistor to OUT.
Can the TPS60132PWP operate from a single Li-ion cell?
Yes, the TPS60132PWP operates across 2.7 V to 5.4 V, fully covering the discharge curve of a single Li-ion or Li-polymer cell (typically 3.0 V to 4.2 V). Its adaptive 1.5×/2× mode switching maintains >85% efficiency throughout this range, and undervoltage lockout disables the device below 1.6 V - preventing deep discharge damage.
What is the purpose of separating GND and PGND pins on the TPS60132PWP?
GND (Pins 1,2,19,20) serves as the analog reference ground for the bandgap, error amplifier, and LBI comparator, ensuring accurate regulation and detection. PGND (Pins 9–12) carries high-frequency, high-current charge-pump return paths. Separating them prevents switching noise from modulating the reference voltage - critical for maintaining ±4% output accuracy and clean LBO transitions.
