Product details
Overview
TPS60132PWPR from Texas Instruments is a regulated 5-V ±4% charge pump DC-DC converter optimized for battery-powered systems requiring compact, inductorless voltage boosting. It delivers up to 150 mA output current from a 2.7-V to 5.4-V input (e.g., three alkaline/NiMH or single Li-ion cells), achieves up to 90% efficiency via adaptive 1.5×/2× mode switching, and draws only 60–100 µA quiescent current at no load.
For engineers reviewing the TPS60132PWPR datasheet, TPS60132PWPR pinout, TPS60132PWPR application, or TPS60132PWPR equivalent, this device is selected for space-constrained portable instrumentation, medical glucose meters, and PCMCIA/Smart Card 5-V supply where low EMI, minimal external components (only four capacitors), and load disconnection during shutdown are critical design requirements.
Technical Context
The TPS60132PWPR implements a dual single-ended charge pump architecture with automatic adaptive mode switching: it selects 1.5× conversion at higher input voltages (≥3.3 V) and voltage-doubling mode at lower inputs (<3.3 V) to maintain high efficiency across the full 2.7–5.4 V range. Its ACTIVE-CYCLE regulation uses fixed-frequency operation under heavy load and pulse-skip mode at light loads to minimize quiescent current.
It integrates a 1.21-V bandgap reference, error amplifier, MOSFET switches with controlled on-resistance, undervoltage lockout (1.6 V threshold), and a dedicated low-battery detector (LBI/LBO) with 1.21 V ±5% trip point. Shutdown disables all switching and isolates the load, reducing supply current to 0.05 µA typical and output leakage to ≤1 µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±4% (4.8–5.2 V); tightly regulated across 2.7–5.4 V input and 0–150 mA load for stable logic/system rail. |
| Max Output Current | 150 mA at 3 V input; sufficient for microprocessor peripherals, Smart Card interfaces, and handheld instrument subsystems. |
| Input Voltage Range | 2.7 V to 5.4 V; supports 3-cell alkaline/NiMH batteries and single-cell Li-ion/Li-polymer without external regulation. |
| Quiescent Current | 60–100 µA; enables long battery life in always-on or low-duty-cycle portable devices. |
| Shutdown Current | 0.05 µA typical; reduces system standby power to near-zero while disconnecting load from input. |
| Switching Frequency | 210–450 kHz internal oscillator; enables use of small ceramic flying/output capacitors and minimizes EMI. |
| Efficiency | Up to 90%; achieved via adaptive 1.5×/2× mode selection and low-RDS(on) MOSFETs, critical for thermal management in sealed enclosures. |
Pinout & Package
TPS60132PWPR is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.50 mm × 4.40 mm, with exposed PowerPAD™ for improved heat dissipation in high-current or high-ambient applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 7, 14) | Supply Input | Dual-input connection for low-impedance path from battery or source; must be bypassed to PGND with capacitor. |
| OUT (Pins 5, 16) | Regulated 5-V Output | Dual-output pins reduce IR drop and improve current sharing; connect together and bypass to GND with CO. |
| GND (Pins 1, 2, 19, 20) | Analog Ground | Reference ground for feedback and control circuitry; separate from PGND to avoid noise coupling into regulation loop. |
| PGND (Pins 9, 10, 11, 12) | Power Ground | High-current return path for charge pump switching; must be shorted to GND with minimal trace inductance. |
| ENABLE (Pin 3) | Enable Control Input | Logic-level enable; tie to IN for always-on operation; drives device into 0.05 µA shutdown when pulled low. |
| FB (Pin 4) | Feedback Input | Connects directly to OUT near load to compensate for PCB trace resistance and ensure accurate 5-V regulation. |
| LBI (Pin 18) | Low-Battery Input | Monitors divided battery voltage against internal 1.21 V reference; connect to ground 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−, C2+, C2− (Pins 6, 8, 15, 13) | Flying Capacitor Terminals | Four dedicated nodes for external ceramic flying caps; define charge transfer path and directly impact ripple/noise. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI, simplifies layout, and reduces BOM count-only four ceramic capacitors required. |
| Adaptive 1.5×/2× mode switching | Maintains >85% efficiency across entire 2.7–5.4 V input range by dynamically selecting optimal voltage gain ratio. |
| ACTIVE-CYCLE regulation | Combines fixed-frequency operation (heavy load) and pulse-skip mode (light load) to achieve both low ripple and ultra-low IQ. |
| Integrated low-battery detector | Programmable trip point (1.15–1.27 V) with hysteresis; provides early warning before system brownout without external comparators. |
| Load isolation in shutdown | Disconnects OUT from IN during disable, preventing battery drain through downstream circuitry or leakage paths. |

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 |
|---|---|---|---|
| TPS60130PWPR | Same 20-pin HTSSOP package and pinout; rated for 300 mA max output (vs. 150 mA for TPS60132PWPR); includes identical LBI/LBO function. | Supports higher-current loads like multi-peripheral microcontrollers or active displays; requires larger output capacitance for stability. | Select TPS60130PWPR when load exceeds 150 mA but board layout and firmware remain unchanged. |
| TPS60111DBVR | 5-V, 150-mA charge pump in 5-pin SOT-23 package; lacks LBI/LBO comparator; uses simpler fixed 2× topology (no adaptive mode). | Suitable for cost-sensitive, space-limited designs where low-battery monitoring is handled externally; lower efficiency below 3.3 V input. | Choose TPS60111DBVR for minimal footprint and BOM count where adaptive efficiency and integrated monitoring are not required. |
Compared with TPS60132PWPR, TPS60130PWPR offers double the output current in identical packaging and feature set, while TPS60111DBVR trades monitoring capability and adaptive efficiency for extreme miniaturization and lower unit cost-making each suitable for distinct power budget, feature, and size constraints.

FAQ
What is the maximum continuous output current of the TPS60132PWPR?
The TPS60132PWPR delivers up to 150 mA of continuous output current when supplied from a 3-V input, as specified in the Electrical Characteristics table. This rating holds across the full operating temperature range (–40°C to +125°C junction) and input voltage range (2.7 V to 5.4 V), with output regulation maintained within ±4% of 5 V. Peak currents beyond 150 mA trigger internal current limiting to protect the device.
Does the TPS60132PWPR require an inductor in its application circuit?
No, the TPS60132PWPR is a charge pump DC-DC converter and does not require an inductor. It operates using four external ceramic capacitors-two flying capacitors (C1, C2) and input/output filter capacitors-to achieve voltage step-up. This inductorless design eliminates magnetic EMI, reduces solution size, and simplifies PCB layout compared to inductive boost converters.
How does the adaptive mode switching work in the TPS60132PWPR?
The TPS60132PWPR automatically selects between 1.5× and 2× voltage conversion modes based on input voltage and load current. At higher inputs (≥3.3 V), it uses 1.5× mode for improved efficiency; at lower inputs (<3.3 V), it switches to 2× mode to sustain regulation. This real-time selection-governed by internal voltage sensing and control logic-maintains >85% efficiency across the full 2.7–5.4 V input range without user intervention.
What is the purpose of the LBI and LBO pins on the TPS60132PWPR?
The LBI (Low-Battery Input) and LBO (Low-Battery Output) pins implement an integrated battery monitoring function. LBI compares a resistor-divided battery voltage to an internal 1.21 V reference; when the divided voltage falls below this threshold, LBO pulls low (open-drain) to signal low battery condition. This eliminates the need for external comparators in portable systems using the TPS60132PWPR.
Can the TPS60132PWPR be used with a single Li-ion battery?
Yes, the TPS60132PWPR is explicitly designed for single Li-ion (or Li-polymer) battery operation, accepting input voltages from 2.7 V to 5.4 V. It starts up reliably at 2.7 V and maintains regulated 5-V output across the full discharge curve (4.2 V → 2.7 V), making it ideal for compact portable devices powered by one-cell lithium chemistry.
