Product details
Overview
TPS60211DGS from Texas Instruments is a regulated 3.3-V step-up charge pump DC/DC converter for battery-powered systems, delivering ≥100 mA continuous output from 1.6–3.6 V input, featuring power-good detection, <5-mVPP output ripple, and 2-µA typical quiescent current in snooze mode. It replaces inductor-based converters in space-constrained medical and portable electronics.
For engineers reviewing the TPS60211DGS datasheet, TPS60211DGS pinout, TPS60211DGS application, or TPS60211DGS equivalent, this page delivers verified electrical specs, MSOP-10 terminal mapping, real-world load/line regulation behavior, and validated alternative options for low-noise, inductorless 3.3-V generation in ultra-low-power systems.
Technical Context
The TPS60211DGS implements a push-pull dual charge-pump topology with 180° phase-shifted flying capacitors (C1/C2), enabling continuous charge transfer to minimize output voltage ripple. Its linskip control seamlessly transitions between constant-frequency linear-regulation mode (>7 mA load) and pulse-skip mode (<7 mA) to optimize efficiency across operating conditions.
It integrates a power-good (PG) open-drain comparator that asserts when output reaches ≥91% of 3.3 V, and supports external clock synchronization up to 800 kHz on the SNOOZE pin. The device operates across −40°C to 85°C and shuts down at input voltages below 1.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% (regulated over 1.6–3.6 V input and 0–100 mA load) |
| Max Continuous Output Current | 100 mA minimum at 2 V input - sufficient for MSP430 microcontrollers and glucose meter sensors |
| Output Ripple | <5 mVPP at full load - enables noise-sensitive analog circuits without additional LDO post-regulation |
| Quiescent Current | 35 µA typical no-load (normal mode); 2 µA typical in snooze mode - extends coin-cell battery life beyond self-discharge rate |
| Snooze Mode Output Limit | 2 mA max load while maintaining 3.3 V ±6% - preserves system state during standby without wake-up latency |
| Power-Good Threshold | 91% of nominal output (≈3.00 V) with 1% hysteresis - provides reliable system reset signaling for microcontrollers |
| Switching Frequency | 200–400 kHz internal; synchronizable to 400–800 kHz external clock - avoids IF band interference and enables EMI-controlled layout |
Pinout & Package
TPS60211DGS is housed in a 10-pin MSOP (DGS) package, 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad (not electrically connected). Pin 1 is marked with a dot; pins are numbered counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI/GND | Ground reference (TPS60211) | Functional GND pin - must be connected to system ground; not used for low-battery detection (distinct from TPS60210) |
| GND | Power ground | Main return path for charge-pump switching currents; requires low-inductance connection to Co and Ci |
| C1− | Flying capacitor negative terminal (C1) | Connects to negative side of 1-µF ceramic flying capacitor; critical for push-pull phase timing |
| C1+ | Flying capacitor positive terminal (C1) | Connects to positive side of C1; alternates conduction with C2+ to enable continuous output charge transfer |
| OUT | Regulated 3.3-V output | Supplies load directly; bypassed with 2.2-µF ceramic capacitor to GND for ripple suppression and transient response |
| LBO/PG | Open-drain power-good output | Active-high PG signal (pulled high via external resistor to OUT); indicates stable 3.3-V rail for system initialization |
| SNOOZE | Mode control input | Low = snooze (2 µA IQ); High = normal operation; AC-coupled clock = synchronized switching - no pullup/pulldown required |
| C2− | Flying capacitor negative terminal (C2) | Completes second charge-pump stage; 180° out-of-phase with C1− to sustain ripple-free output current |
| IN | Input supply (1.6–3.6 V) | Bypassed with 2.2-µF ceramic capacitor; supports two alkaline/NiMH cells or single Li-MnO₂ coin cell |
| C2+ | Flying capacitor positive terminal (C2) | Alternates with C1+ to drive output; enables >90% efficiency without magnetic components |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TPS60210DGS | Same 100-mA output and 3.3-V regulation, but features low-battery detector (LBI/LBO) instead of power-good (PG) | Used where battery voltage monitoring is prioritized over rail-valid signaling - e.g., primary-cell consumer devices with end-of-life warning | Select TPS60210DGS if system requires early battery depletion alert; TPS60211DGS is preferred when deterministic power sequencing is critical |
| TPS60213DGS | Identical PG functionality and pinout, but rated for only 50 mA continuous output and narrower input range (1.8–3.6 V) | Suitable for lower-power peripherals like I²C sensors or RTCs where 100 mA headroom is unnecessary | Choose TPS60213DGS to reduce cost in low-current applications; TPS60211DGS ensures margin for peak loads in mixed-signal systems |

FAQ
What is the minimum input voltage required for TPS60211DGS to start up and regulate?
The TPS60211DGS starts up and regulates continuously down to 1.6 V input. During start-up, the input is precharged to 0.8 × VI before activating the charge-pump stages, ensuring fast ramp-up and limiting inrush current into the output capacitor. This allows reliable operation from nearly depleted alkaline or NiMH cells, extending usable battery capacity beyond conventional boost converters.
How does the power-good (PG) function of TPS60211DGS differ from the low-battery detector in TPS60210DGS?
The TPS60211DGS PG pin is an open-drain output that goes high-impedance until the regulated 3.3-V output reaches ≥91% of nominal (≈3.00 V), then pulls high via external resistor. In contrast, TPS60210DGS uses LBI/LBO to monitor input voltage against a 1.18-V threshold. PG validates output rail integrity for system boot; LBO warns of declining input - they serve fundamentally different system-level functions.
Can TPS60211DGS operate without external capacitors?
No - the TPS60211DGS requires four external ceramic capacitors: two 1-µF flying capacitors (C1/C2), one 2.2-µF input capacitor (Ci), and one 2.2-µF output capacitor (Co). These are integral to the push-pull charge-pump operation and ripple suppression. Omitting any capacitor prevents regulation, causes instability, or damages the IC due to uncontrolled voltage transients.
What is the maximum load current TPS60211DGS can deliver at 1.8-V input?
At 1.8-V input, the TPS60211DGS delivers ≥100 mA continuous output while maintaining 3.3 V ±4%, as confirmed in the datasheet's electrical characteristics table. Peak current capability exceeds 150 mA, supporting short-duration bursts for radio transmission or display backlighting without output droop.
Does TPS60211DGS require a specific capacitor dielectric type?
Yes - only X5R or X7R ceramic capacitors are recommended for C1, C2, Ci, and Co. These dielectrics maintain stable capacitance across temperature and DC bias. Z5U or Y5V types exhibit severe capacitance loss at voltage or temperature extremes, degrading regulation accuracy, ripple performance, and load transient response - risking system malfunction.
