Product details
Overview
TPS60211DGSRG4 from Texas Instruments is a regulated 3.3-V, 100-mA step-up charge pump DC/DC converter for battery-powered systems. It operates from 1.6 V to 3.6 V input, delivers ≤5-mVPP output ripple via push-pull topology, and features power-good detection (PG) with 91% VOUT trip threshold - used in glucose meters, MSP430-based portable instruments, and backup-battery boost applications.
For engineers reviewing the TPS60211DGSRG4 datasheet, TPS60211DGSRG4 pinout, TPS60211DGSRG4 application, or TPS60211DGSRG4 equivalent, key selection criteria include its 2-µA snooze-mode quiescent current, 35-µA no-load operating current, 10-pin MSOP package, and absence of inductors - critical for ultra-low-power, space-constrained medical and portable audio designs.
Technical Context
The TPS60211DGSRG4 implements dual single-ended charge pumps operating in 180° push-pull phase to ensure continuous charge transfer, eliminating the high inherent ripple of conventional charge pumps. Its regulation uses linskip mode: seamless transition between constant-frequency linear-regulation (>7 mA load) and pulse-skip mode (<7 mA), minimizing quiescent current while maintaining ±4% output accuracy.
It integrates a power-good detector (open-drain PG pin) that asserts when VOUT ≥ 91% of nominal 3.3 V, and supports external clock synchronization up to 800 kHz on the SNOOZE pin. Snooze mode (SNOOZE = GND) reduces IQ to 2 µA while limiting output current to 2 mA and relaxing regulation to ±6% - ideal for standby operation in battery-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 3.3 V ±4% (1.8–3.6 V input, full load); maintains regulation across 100 mA continuous output. |
| Input voltage range | 1.6 V to 3.6 V - supports two alkaline/NiMH cells or one Li-MnO₂ coin cell down to end-of-life. |
| Quiescent current | 35 µA typical (no load, normal mode); enables >90% efficiency at mid-load and extends battery runtime. |
| Snooze-mode IQ | 2 µA typical - lower than typical battery self-discharge, enabling multi-year shelf life in standby. |
| Output ripple | <5 mVPP at 100 mA - achieved via push-pull topology and no inductor, reducing EMI and layout complexity. |
| Switching frequency | 200–400 kHz internal; synchronizable to 400–800 kHz external clock - avoids IF band interference and enables EMI control. |
| Power-good threshold | 91% of 3.3 V (≈3.00 V) - provides reliable system power sequencing and brownout warning without external circuitry. |
Pinout & Package
TPS60211DGSRG4 is housed in a 10-pin MSOP (DGS) package - 3.0 mm × 3.0 mm × 1.0 mm, thermally enhanced with exposed pad (not electrically connected). Pin numbering follows standard DGS outline with pin 1 at top-left corner (LBI/GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI/GND | Ground reference / unused low-battery input | Functionally GND only - not connected to internal comparator; must be tied to system ground for proper operation. |
| GND | Power ground | Main return path for flying capacitors, input/output bypass, and internal circuitry; requires low-inductance connection. |
| C1−, C1+ | Flying capacitor terminals (Charge Pump 1) | Form first half of push-pull charge transfer stage; require 1-µF low-ESR ceramic (X5R/X7R) capacitor. |
| C2−, C2+ | Flying capacitor terminals (Charge Pump 2) | Phase-shifted 180° from C1; completes continuous charge delivery to output; same capacitor requirements as C1. |
| IN | Input supply | Accepts 1.6–3.6 V; bypassed with ≥2.2-µF ceramic capacitor to minimize input impedance and stabilize source current. |
| OUT | Regulated 3.3-V output | Delivers up to 100 mA; requires ≥2.2-µF ceramic output capacitor (Co) for ripple suppression and transient response. |
| LBO/PG | Open-drain power-good indicator | Asserts high-impedance → pulled low when VOUT < 91% of 3.3 V; requires external pullup to OUT or logic rail ≤3.6 V. |
| SNOOZE | Mode control input | Low = snooze (2 µA IQ, 2 mA max load); high = normal operation; AC signal = external sync (max 800 kHz). |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic components, reducing EMI, board area, and BOM cost - critical for compact medical and wearable devices. |
| Push-pull charge pump topology | Ensures continuous charge flow to output, achieving <5-mVPP ripple without large output capacitance or post-regulation. |
| Programmable operating modes | Snooze (2 µA), normal (linskip), and external-sync modes enable dynamic power optimization across use cases and battery states. |
| Integrated power-good detection | Provides system-level power sequencing and fault indication using only one open-drain pin - no external comparators needed. |
| Ultra-low quiescent current | 35 µA no-load and 2 µA snooze current directly extend battery life in intermittent-use portable instrumentation. |
Applications
| Glucose Meter Power Supply | MSP430-Based Portable Instrument |
|---|---|
Use Scenario: Battery-powered handheld glucose meter requiring stable 3.3-V rail for ADC, LCD, and microcontroller during brief active measurement cycles and long idle periods. IC Role / Device Role / Timing Role: Primary regulated boost converter supplying main system rail; PG pin triggers MCU wake-up upon valid power; snooze mode sustains RTC during sleep. Use Value: 2-µA snooze current enables multi-year battery life; ≤5-mVPP ripple ensures ADC accuracy without additional LDO filtering. |
Use Scenario: Low-power data logger using MSP430FR5969, powered by two AA alkaline cells, needing clean 3.3-V supply for RF transmission and sensor acquisition. IC Role / Device Role / Timing Role: Main DC/DC converter; SNOOZE pin controlled by MCU GPIO to enter ultra-low-power state between sampling intervals. Use Value: Push-pull topology eliminates inductor EMI near sensitive RF front-end; 90% peak efficiency preserves battery capacity over thousands of cycles. |
| Backup-Battery Boost Converter | MP3 Player System Rail |
Use Scenario: Real-time clock (RTC) backup circuit using CR2032 coin cell to maintain time during main power loss in industrial controllers. IC Role / Device Role / Timing Role: Standby boost converter activated only when main VCC drops; PG pin signals valid backup rail to system supervisor. Use Value: 1.6-V minimum input allows full utilization of CR2032 (nominal 3 V, end-of-life ~2 V); 2-µA IQ prevents premature battery depletion. |
Use Scenario: Portable MP3 player with dual-cell alkaline input (1.8–3.2 V) powering DSP, flash memory, and audio codec from single 3.3-V rail. IC Role / Device Role / Timing Role: Primary system power converter; synchronized switching (via external clock) avoids audible beat frequencies in audio band. Use Value: External clock sync (up to 800 kHz) shifts switching harmonics away from 20 Hz–20 kHz audio band, preventing speaker noise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60210DGSR | Features low-battery detector (LBI/LBO) instead of power-good (PG); identical pinout, package, and 100-mA output capability. | Used where battery voltage monitoring is required (e.g., PDA fuel gauging); incompatible with PG-driven power sequencing. | Select TPS60210DGSR only if low-battery warning is mandatory and PG functionality is unnecessary. |
| MAX17222ETA+ | 300-mA synchronous boost with integrated inductor; higher output current but requires inductor and has 25-µA IQ (no snooze mode). | Preferred for higher-current loads (>100 mA) or where tighter output tolerance (<±2%) is required; unsuitable for inductor-free layouts. | Choose MAX17222ETA+ when load exceeds 100 mA or when system-level power sequencing does not rely on PG assertion timing. |
Compared with TPS60211DGSRG4, TPS60210DGSR offers identical form-factor and efficiency but swaps PG for LBO - making it suitable for battery-monitoring rather than power-sequencing roles. The MAX17222ETA+ delivers higher current and better regulation but introduces inductor-related EMI and lacks ultra-low-power snooze capability.

FAQ
What is the minimum input voltage supported by the TPS60211DGSRG4?
The TPS60211DGSRG4 supports a minimum input voltage of 1.6 V, enabling full operation down to end-of-life voltage of common primary lithium (Li-MnO₂) coin cells and two-cell alkaline/NiMH batteries. This ensures maximum usable battery capacity in portable medical and consumer devices.
How does the power-good (PG) function work on the TPS60211DGSRG4?
The TPS60211DGSRG4's PG pin is an open-drain output that releases (goes high-impedance) when VOUT reaches ≥91% of 3.3 V (≈3.00 V) and pulls low when VOUT falls below that threshold. An external pullup resistor (100 kΩ–1 MΩ to OUT or another ≤3.6 V rail) is required for proper logic-level signaling.
Can the TPS60211DGSRG4 operate without external capacitors?
No - the TPS60211DGSRG4 requires four external ceramic capacitors: two 1-µF flying capacitors (C1, C2), one 2.2-µF input capacitor (CIN), and one 2.2-µF output capacitor (COUT). Omitting any violates the push-pull charge transfer architecture and will prevent regulation or cause instability.
What is the purpose of the SNOOZE pin on the TPS60211DGSRG4?
The SNOOZE pin on the TPS60211DGSRG4 controls three operating modes: low = snooze (2 µA IQ, ±6% regulation, 2 mA max load), high = normal linskip operation, and AC signal = external clock synchronization (400–800 kHz). It enables dynamic power-state adaptation without external logic.
Is the TPS60211DGSRG4 RoHS-compliant and lead-free?
Yes - the TPS60211DGSRG4 is manufactured in accordance with Texas Instruments' Green Policy and meets RoHS Directive 2011/65/EU requirements, including lead-free terminal finish and halogen-free packaging. Full compliance documentation is available in TI's official product change notices.
