Product details
Overview
TPS60212DGSRG4 from Texas Instruments is a regulated 3.3-V, 50-mA step-up charge pump DC/DC converter for ultra-low-power battery systems. It operates from 1.6 V to 3.6 V input, delivers ≤5-mVPP output ripple via push-pull topology, and features integrated low-battery detection with 1.18-V threshold. It powers MSP430 microcontrollers, glucose meters, and portable audio devices requiring inductorless, compact power conversion.
For engineers reviewing the TPS60212DGSRG4 datasheet, TPS60212DGSRG4 pinout, TPS60212DGSRG4 application, or TPS60212DGSRG4 equivalent, key selection criteria include its 2-µA snooze-mode quiescent current, 50-mA continuous output at 2-V input, 10-pin MSOP package, and compatibility with ceramic-only external capacitors (C1/C2 = 0.47 µF, CIN/COUT = 2.2 µF).
Technical Context
The TPS60212DGSRG4 uses dual single-ended charge pumps operating in 180° phase-shifted push-pull mode to sustain continuous charge transfer, eliminating high ripple inherent in conventional charge pumps. Its linskip control architecture seamlessly transitions between constant-frequency linear-regulation mode (>7 mA load) and pulse-skip mode (<7 mA), optimizing efficiency across load range.
It integrates a precision low-battery detector (LBI/LBO) with 1.18-V ±5% trip voltage and 10-mV hysteresis, configurable via external resistor divider. The SNOOZE pin enables three operational states: snooze mode (2 µA IQ, 2 mA max load), normal mode (internal 200–400 kHz oscillator), or external clock synchronization (400–800 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% (regulated over 1.6–3.6 V input and 0–50 mA load) |
| Max Continuous Output Current | 50 mA at 2-V input (enables use with two alkaline/NiMH cells or coin cells) |
| Output Ripple | <5 mVPP (achieved via push-pull topology and 2.2-µF ceramic output capacitor) |
| Quiescent Current | 35 µA typical (no-load, normal mode); 2 µA typical (snooze mode, preserves battery shelf life) |
| Snooze Mode Load Limit | 2 mA maximum (maintains 3.3 V ±6% while drawing only 2 µA from source) |
| Switching Frequency | 200–400 kHz internal; synchronizable to 400–800 kHz external clock (avoids IF band interference) |
| Low-Battery Threshold | 1.18 V ±5% on LBI pin (configurable via resistor divider; LBO is open-drain with pullup required) |
Pinout & Package
TPS60212DGSRG4 is housed in a 10-pin MSOP (DGS) package - 3.0 mm × 3.0 mm × 1.0 mm, exposed pad optional - optimized for space-constrained portable designs. All pins are surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI | Low-battery detector input | Accepts voltage divider from input; trips at 1.18 V ±5%; connect to GND if unused |
| GND | Ground reference (pins 2 and ?) | Dual ground pins (pin 2 and pin ? per DGS pinout) reduce ground impedance and improve PSRR |
| C1− / C1+ | Flying capacitor terminals (1) | Connect 0.47 µF ceramic (X5R/X7R); phase-shifted with C2 to enable push-pull charge transfer |
| C2− / C2+ | Flying capacitor terminals (2) | Complements C1 in 180° push-pull operation; both flying caps share same value and type |
| IN | Input supply (1.6–3.6 V) | Bypassed with ≥2.2 µF ceramic capacitor; supports single Li-MnO₂ or dual alkaline/NiMH cells |
| OUT | Regulated 3.3-V output | Delivers up to 50 mA; requires ≥2.2 µF ceramic output capacitor for <5-mV ripple |
| LBO | Open-drain low-battery output | Pulled low when LBI < 1.18 V; requires external pullup (100 kΩ–1 MΩ) to OUT or logic rail ≤3.6 V |
| SNOOZE | Mode control input | LOW = snooze (2 µA IQ); HIGH = normal (internal oscillator); AC signal = sync mode |
Key Features

| Linskip adaptive control | Automatically switches between constant-frequency (low-noise) and pulse-skip (high-efficiency) modes based on 7-mA threshold |
| Ultra-low snooze current | 2 µA typical IQ maintains regulation while consuming less than most battery self-discharge rates |
| Integrated low-battery detector | 1.18-V ±5% comparator with user-configurable trip point via resistor divider; LBO open-drain simplifies host interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar charge pump DC/DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60210DGS | 100-mA output capability; identical pinout and low-battery detector; higher peak current rating | Required where sustained >50 mA load (e.g., multi-sensor nodes with active RF) is needed | Select TPS60210DGS when system peak current exceeds 50 mA but low-battery warning remains essential |
| TPS60213DGSR | 50-mA output; power-good (PG) instead of low-battery (LBO); same package and electrical specs otherwise | Preferred in systems needing output-valid confirmation (e.g., FPGA configuration sequencing) rather than battery monitoring | Choose TPS60213DGSR when host processor requires PG assertion before enabling peripherals, not battery status |
Compared with TPS60210DGS, TPS60212DGSRG4 trades 100-mA capability for lower cost and smaller solution size at 50 mA; versus TPS60213DGSR, it provides battery health awareness instead of output validation-making it optimal for long-life, battery-critical portable instrumentation.

FAQ
What is the minimum input voltage supported by the TPS60212DGSRG4?
The TPS60212DGSRG4 supports a minimum input voltage of 1.6 V, enabling full utilization of two NiMH/NiCd cells down to end-of-discharge or single lithium coin cells through their entire usable voltage range. This is confirmed in the Recommended Operating Conditions table (SLVS296, p.7) and validated across load conditions in Figure 10 (output voltage vs. input voltage at 1 mA, 25 mA, and 50 mA).
How does the TPS60212DGSRG4 achieve low output voltage ripple without inductors?
The TPS60212DGSRG4 achieves <5-mVPP output ripple using a push-pull topology with two phase-shifted (180°) charge pumps. While one pump charges its flying capacitor (C1), the other transfers stored charge to the output - ensuring continuous current delivery to the load and minimizing reliance on output capacitance for ripple suppression. This is detailed in the "Push-Pull Operating Mode" section (SLVS296, p.4–5).
What is the function of the SNOOZE pin on the TPS60212DGSRG4?
The SNOOZE pin on the TPS60212DGSRG4 controls three distinct operating modes: LOW enables snooze mode (2 µA IQ, 2 mA max load, 3.3 V ±6%); HIGH enables normal operation (internal 200–400 kHz oscillator); and an AC signal enables external clock synchronization (400–800 kHz). This is specified in the Terminal Functions table (SLVS296, p.4) and functional block diagram (p.3).
Can the TPS60212DGSRG4 be used with ceramic-only external components?
Yes - the TPS60212DGSRG4 is designed exclusively for ceramic capacitors: 0.47 µF for C1/C2, 2.2 µF for CIN and COUT. X5R or X7R dielectrics are recommended to maintain capacitance across temperature and bias. Inductors are not required or supported, as confirmed in the Features list (SLVS296, p.1) and Capacitor Selection section (p.14–15).
What is the purpose of the LBI and LBO pins on the TPS60212DGSRG4?
LBI is the low-battery detector input, referenced to an internal 1.18-V ±5% threshold; a resistor divider from input sets the trip point. LBO is an open-drain output that pulls low when LBI falls below threshold. Both pins are specific to TPS60212DGSRG4 (and TPS60210), unlike the PG pin on TPS60211/213. Details are in the Electrical Characteristics tables (p.8) and Figure 2 (p.6).
