Product details
Overview
TPS60133PWPR from Texas Instruments is a regulated 5-V, 150-mA charge pump DC-DC converter optimized for battery-powered systems requiring inductorless voltage boosting. 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, features Power Good (PG) open-drain output, and achieves up to 90% efficiency using adaptive 1.5×/2× mode switching. It is used in portable medical devices like glucose meters where compact size and low EMI are critical.
For engineers reviewing the TPS60133PWPR datasheet, TPS60133PWPR pinout, TPS60133PWPR application, or TPS60133PWPR equivalent, key selection considerations include its 150-mA output current rating, 60-µA quiescent current, 0.05-µA shutdown current, PG comparator threshold at 0.9 × VO with 0.8% hysteresis, and HTSSOP-20 thermal performance (RθJA = 178.75°C/W).
Technical Context
The TPS60133PWPR implements dual single-ended charge pumps with automatic 1.5× or 2× conversion ratio selection based on input voltage and load current to maximize efficiency across its 2.7–5.4 V input range. Its control loop uses ACTIVE-CYCLE regulation-fixed-frequency operation at heavy loads and pulse-skip mode at light loads-to maintain low output ripple while minimizing quiescent current.
It integrates a 1.21-V bandgap reference, error amplifier, high-current MOSFET switches, shutdown logic, and a Power Good comparator. The PG pin (Pin 17) is an open-drain output that asserts low when VO falls below 0.9 × VO (±0.04 × VO hysteresis), with 1 mA sink capability and 0.4 V max low-level voltage at 1 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5 V ±4% - tightly regulated rail for USB-peripheral or microcontroller I/O supply without external feedback resistors. |
| Max Output Current | 150 mA at 3 V input - sufficient for low-power MCU cores, sensors, and interface ICs in handheld instruments. |
| Input Voltage Range | 2.7 V to 5.4 V - supports 3-cell alkaline/NiMH stacks and single-cell Li-ion/Li-poly batteries directly. |
| Quiescent Current | 60 µA typical - enables >1-year battery life in always-on portable instrumentation with periodic wake-up. |
| Shutdown Current | 0.05 µA typical - isolates load from input and minimizes standby drain in battery backup systems. |
| Switching Frequency | 210–450 kHz internal - avoids AM radio band, simplifies EMI filtering, and enables use of small ceramic capacitors. |
| Power Good Threshold | 0.9 × VO with 0.8% hysteresis - provides reliable system reset or supervisor signaling without external comparators. |
| Thermal Resistance | RθJA = 178.75°C/W (HTSSOP-20) - requires minimal PCB copper area for thermal management in space-constrained designs. |
Pinout & Package
TPS60133PWPR is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.50 mm × 4.40 mm, with exposed thermal pad (PowerPAD™) for improved heat dissipation. Four ground pins (GND: Pins 1, 2, 19, 20) and four power ground pins (PGND: Pins 9–12) enable low-impedance return paths for analog and switching currents respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENABLE (Pin 3) | Digital enable input | Active-high logic control; ties to IN for always-on operation; pulls low to reduce supply current to 0.05 µA and disconnect load. |
| FB (Pin 4) | Internal feedback node | Connected directly to OUT; internal 1.21-V reference and resistive divider eliminate need for external resistors. |
| IN (Pins 7, 14) | Main power input | Dual pins reduce trace resistance and inductance; must be shorted together and bypassed to PGND with capacitor ≥½ CO. |
| OUT (Pins 5, 16) | Regulated 5-V output | Dual pins lower output impedance; connect together and bypass to GND with low-ESR ceramic capacitor (10–100 µF). |
| PG (Pin 17) | Power Good open-drain output | Asserts low when VO < 0.9 × VO; requires 100-kΩ–1-MΩ pullup to OUT; sinks 1 mA; invalid for first 500 µs after startup. |
| C1+, C1−, C2+, C2− (Pins 6, 8, 13, 15) | Flying capacitor terminals | Four dedicated nodes for two external ceramic flying caps (C1, C2); low-ESR ceramics mandatory for stable 1.5×/2× switching. |
| GND (Pins 1, 2, 19, 20) | Analog ground reference | Reference for internal bandgap, error amp, and comparator; connect to PGND via short, low-inductance trace near IC. |
| PGND (Pins 9–12) | Power ground return | Carries high-frequency charge-pump switching current; tie all four pins to solid ground plane under thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI, board area, and cost of inductors; enables ultra-thin portable designs like PDA mainboards. |
| Adaptive 1.5×/2× mode switching | Automatically selects optimal conversion ratio to sustain >85% efficiency across full 2.7–5.4 V input and 1–150 mA load range. |
| Pulse-skip light-load regulation | Reduces switching activity at light loads, cutting IQ to 60 µA and maintaining low output ripple without external compensation. |
| Integrated Power Good comparator | Provides system-level voltage supervision with precise 0.9 × VO trip point and built-in hysteresis-no external components needed. |
| Thermally enhanced PowerPAD™ | Exposed die-pad in HTSSOP-20 lowers junction-to-board thermal resistance to 3.5°C/W, enabling 150 mA continuous output in 40°C ambient. |
| Load isolation in shutdown | Disconnects OUT from IN during ENABLE = low, preventing backfeed and enabling safe hot-swap or battery replacement. |

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 |
|---|---|---|---|
| TPS60131PWPR | Same HTSSOP-20 package and 300-mA output rating, but includes Power Good (PG) output identical to TPS60133PWPR; differs only in higher current capability. | Used where 300-mA peak load (e.g., LCD backlight + MCU) is required alongside PG supervision-unsuitable if board layout or BOM must match 150-mA thermal limits. | Select TPS60131PWPR only if load current exceeds 150 mA and thermal margin allows higher dissipation. |
| MAX680ESA+ | 5-V, 100-mA charge pump in 8-pin SOIC; lacks integrated PG comparator, requires external feedback resistors, and has fixed 2× topology (no adaptive mode switching). | Suitable for cost-sensitive, low-complexity designs where ±5% output tolerance and basic boost functionality suffice-no PG or tight regulation needed. | Choose MAX680ESA+ only for legacy designs with SOIC footprint and relaxed regulation specs; not drop-in compatible. |
Compared with TPS60133PWPR, TPS60131PWPR offers higher output current but identical PG functionality and package, while MAX680ESA+ trades integration and regulation accuracy for smaller size and lower cost-making TPS60133PWPR optimal for new designs demanding 150-mA capability, PG supervision, and minimal external components.

FAQ
What is the maximum continuous output current of the TPS60133PWPR?
The TPS60133PWPR delivers up to 150 mA of continuous output current when supplied from a 3-V input, as specified in the Recommended Operating Conditions table of the SLVS258B datasheet. This rating applies across the full operating temperature range (–40°C to +125°C junction) and accounts for thermal derating in the HTSSOP-20 package. Exceeding this current may trigger internal current limiting or thermal shutdown.
Does the TPS60133PWPR require external feedback resistors to regulate its 5-V output?
No, the TPS60133PWPR does not require external feedback resistors. It integrates an internal resistive divider and 1.21-V bandgap reference, with the FB pin (Pin 4) connected directly to the OUT pin. This internal feedback network ensures ±4% output regulation across line, load, and temperature without any external components.
How does the Power Good (PG) output on the TPS60133PWPR function?
The PG pin (Pin 17) on the TPS60133PWPR is an open-drain output that pulls low when the regulated output voltage falls below 0.9 × VO (i.e., 4.5 V nominal), with 0.8% hysteresis to prevent chatter. It sinks up to 1 mA and requires a 100-kΩ to 1-MΩ pullup resistor to OUT. The signal is invalid for the first 500 µs after startup.
Can the TPS60133PWPR operate from a single Li-ion battery?
Yes, the TPS60133PWPR operates across 2.7 V to 5.4 V input, fully covering the discharge curve of a single Li-ion or Li-polymer cell (typically 4.2 V fully charged down to 2.7 V cutoff). Its adaptive 1.5×/2× mode switching maintains high efficiency (>85%) throughout this range, making it ideal for single-cell portable systems.
What is the shutdown current consumption of the TPS60133PWPR?
The TPS60133PWPR draws just 0.05 µA typical (1 µA maximum) supply current in shutdown mode, achieved by driving the ENABLE pin low. In this state, all internal switches, oscillator, and control logic are disabled, and the output is disconnected from the input-minimizing battery drain in standby or storage modes.
