Product details
Overview
TPS60124PWPR from Texas Instruments is a regulated 200-mA, 3-V ±4% charge-pump DC/DC converter in a 20-pin PowerPAD (PWP) package, designed for two-cell alkaline/NiMH battery-powered systems. It operates from 1.8 V to 3.6 V input, delivers ≥200 mA at 3 V with 55 µA quiescent current, and integrates low-battery detection (LBI/LBO) - used in glucose meters and portable audio players.
For engineers reviewing the TPS60124PWPR datasheet, TPS60124PWPR pinout, TPS60124PWPR application, or TPS60124PWPR equivalent, this page provides verified technical context, adaptive 1.5×/2× mode switching behavior, confirmed 20-pin PWP package mapping, real-world load regulation (0.003%/mA), and validated alternatives for 3-V regulated boost applications.
Technical Context
The TPS60124PWPR uses dual single-ended charge pumps with ACTIVE-CYCLE regulation: fixed-frequency operation at high load (210–450 kHz) and pulse-skip mode at light load to minimize quiescent current. Its adaptive mode switching selects 1.5× gain above ~2.4 V input and 2× gain below, optimizing efficiency across the full 1.8–3.6 V battery range.
It features integrated 1.21-V bandgap reference, internal resistive feedback (no external divider needed), undervoltage lockout (1.6 V), short-circuit current limit (115 mA), and dedicated LBI/LBO pins for programmable low-battery detection - all implemented without inductors and with only four external ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.0 V ±4% - tightly regulated output suitable for 3-V logic rails and analog subsystems without external feedback resistors. |
| Max Output Current | 200 mA continuous - sufficient to power microcontrollers, LCD backlights, or RF modules from two-cell batteries. |
| Input Voltage Range | 1.8 V to 3.6 V - matches discharge curve of two alkaline/NiMH cells (1.0–1.8 V per cell). |
| Quiescent Current | 55 µA typical - extends battery life in always-on portable instrumentation with infrequent active cycles. |
| Shutdown Current | 0.05 µA - isolates load from battery during sleep, critical for multi-year battery life in medical devices. |
| Switching Frequency | 210–450 kHz - enables use of small 2.2-µF ceramic flying capacitors and minimizes EMI in noise-sensitive analog circuits. |
| Low-Battery Detection | Integrated LBI/LBO with 1.21 V ±5% trip threshold - allows precise battery end-of-life signaling via external resistor divider. |
Pinout & Package
TPS60124PWPR is housed in a thermally enhanced 20-pin PowerPAD (PWP) package with exposed thermal pad for improved power dissipation (700 mW at 25°C). Pin numbering follows standard top-view layout with GND/PGND pins distributed for low-impedance return paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (7,14) | Input supply connection | Dual-pin input for low-impedance path from 1.8–3.6 V battery source; bypassed to PGND with 10-µF ceramic capacitor. |
| OUT (5,16) | Regulated output node | Dual-pin 3.0 V output delivering up to 200 mA; bypassed to GND with 22-µF ceramic capacitor for ripple suppression. |
| ENABLE (3) | Logic-controlled enable input | Active-high control: drives device into shutdown (0.05 µA IQ) when pulled low; connects directly to IN for always-on operation. |
| FB (4) | Feedback input | Internally connected to 1.21-V reference; tied directly to OUT for 3.0-V regulation - no external resistors required. |
| LBI (18) | Low-battery comparator input | Accepts voltage divider from battery to trigger LBO at user-defined threshold (e.g., 1.8 V min); grounded if unused. |
| LBO (17) | Open-drain low-battery output | Sinks 1 mA when triggered; requires 100-kΩ–1-MΩ pullup to OUT; invalid for first 500 µs after startup. |
| C1+/C1− (6,8), C2+/C2− (15,13) | Flying capacitor terminals | Four dedicated pins for two 2.2-µF ceramic flying caps enabling charge-pump voltage multiplication without inductors. |
| GND (1,2,19,20), PGND (9–12) | Analog & power ground returns | Separate GND (reference/control) and PGND (switching current) pins reduce noise coupling; must be shorted externally. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive 1.5×/2× mode switching | Automatically selects optimal conversion ratio based on input voltage and load - maintains >85% efficiency across full battery discharge range. |
| No-inductor architecture | Eliminates magnetic EMI and board space for inductors; reduces BOM count to just four ceramic capacitors for complete solution. |
| Pulse-skip light-load regulation | Halts switching when output exceeds regulation threshold, cutting IQ to 55 µA and isolating load to preserve battery energy. |
| Integrated low-battery detector | On-chip 1.21-V comparator with LBI/LBO pins enables accurate, resistor-programmable battery monitoring without external ICs. |
| Thermally enhanced PWP package | 20-pin PowerPAD with exposed thermal pad achieves 178°C/W θJA - supports 200-mA operation in compact portable enclosures. |

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 |
|---|---|---|---|
| TPS60120PWPR | 3.3-V output (±4%), same 200-mA rating and PWP package; includes LBI/LBO but no power-good output. | Used where 3.3-V logic compatibility is required instead of 3.0 V; identical pinout and external component set. | Select TPS60120PWPR when system I/O voltage mandates 3.3 V; otherwise TPS60124PWPR avoids level-shifting overhead for 3-V peripherals. |
| MAX680ESA+ | 3.3-V fixed output, 100-mA max, 8-pin SOIC package; no integrated low-battery detection or adaptive mode switching. | Targeted at space-constrained, lower-current applications where 3.3-V output suffices and battery monitoring is handled externally. | Choose MAX680ESA+ only for legacy designs with existing 8-pin footprints and ≤100 mA loads; lacks TPS60124PWPR's efficiency optimization and diagnostic features. |
Compared with TPS60120PWPR, TPS60124PWPR trades 3.3-V compatibility for tighter 3.0-V regulation suited to ultra-low-power 3-V microcontrollers, while retaining identical low-battery detection and thermal performance. Against MAX680ESA+, it delivers double the current, advanced adaptive control, and integrated diagnostics - at the cost of larger PWP footprint.

FAQ
What output voltage does the TPS60124PWPR regulate to, and is external feedback required?
The TPS60124PWPR regulates to a fixed 3.0 V ±4% output. It uses an internal resistive divider matched to a 1.21-V bandgap reference, so no external feedback resistors are needed - FB pin is connected directly to OUT. This simplifies layout and improves regulation accuracy versus adjustable converters requiring precision external components.
Does the TPS60124PWPR support automatic mode switching, and how does it affect efficiency?
Yes, the TPS60124PWPR implements adaptive 1.5×/2× mode switching: it uses 2× gain below ~2.4 V input and 1.5× gain above, dynamically optimizing efficiency across the 1.8–3.6 V battery range. At 2.0 V/100 mA, efficiency reaches 85%; at 2.7 V/100 mA, it remains >82% - eliminating manual mode selection and maximizing runtime.
How is low-battery detection implemented on the TPS60124PWPR, and what accuracy can be expected?
The TPS60124PWPR includes dedicated LBI and LBO pins. LBI compares battery voltage against an internal 1.21-V ±5% reference; trip point is set via external R1/R2 divider. With ±1% resistors, total accuracy is ±6%. LBO is open-drain and requires a 100-kΩ–1-MΩ pullup to OUT - enabling precise, programmable battery end-of-life signaling without extra ICs.
What are the key capacitor requirements for stable operation of the TPS60124PWPR?
The TPS60124PWPR requires four ceramic capacitors: 10-µF input (Ci), two 2.2-µF flying caps (C1, C2), and 22-µF output (Co). All must be X7R dielectric with low ESR (<0.1 Ω). Ci and Co stabilize input/output rails; C1/C2 enable charge transfer. Using incorrect types or values causes instability, excessive ripple, or failure to start - especially below 1.8 V.
Can the TPS60124PWPR be used in shutdown mode to isolate the load, and what is the leakage current?
Yes - driving ENABLE low places the TPS60124PWPR in shutdown, reducing supply current to 0.05 µA typical and disconnecting the load from the input. Output leakage current is ≤1 µA at VI = 2.4 V, ensuring minimal battery drain during storage or standby. Shutdown exit time is ~10 µs, supporting fast wake-up in responsive portable systems.
