Product details
Overview
TPS60210DGS from Texas Instruments is a regulated 3.3-V step-up charge pump IC designed for space-constrained, battery-powered systems. It accepts 1.6–3.6-V input (e.g., two alkaline/NiMH cells), delivers ≥100 mA continuous output current, maintains ±4% output regulation, and achieves <5-mVPP ripple using push-pull topology-enabling inductorless 3.3-V supply in glucose meters, MSP430-based devices, and portable audio.
For engineers reviewing the TPS60210DGS datasheet, TPS60210DGS pinout, TPS60210DGS application, or TPS60210DGS equivalent, key selection criteria include its 2-µA snooze-mode quiescent current, integrated low-battery detector (LBI/LBO), 10-pin MSOP (DGS) package, and synchronization-capable SNOOZE pin for EMI control in ultra-low-power embedded designs.
Technical Context
The TPS60210DGS implements a dual single-ended charge-pump architecture operating in 180° push-pull phase to ensure continuous charge transfer, eliminating the high ripple typical of conventional charge pumps. Its regulation combines constant-frequency linear mode (>7 mA load) and pulse-skip mode (<7 mA) to balance noise, efficiency, and quiescent current.
It integrates a low-battery detector with 1.18-V ±5% trip threshold on LBI and open-drain LBO output, plus start-up precharge, short-circuit limiting (~60 mA), and external clock synchronization up to 800 kHz applied to the SNOOZE pin-supporting deterministic EMI management without layout changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% over 1.6–3.6-V input and 0–100 mA load-ensures stable MCU core/logic rail without external LDO. |
| Input Voltage Range | 1.6 V to 3.6 V-supports full discharge of two alkaline/NiMH cells or one Li-MnO₂ coin cell. |
| Max Continuous Output Current | 100 mA at VIN ≥ 2 V-sufficient for MSP430 active-mode operation and sensor subsystems. |
| Quiescent Current | 35 µA typical at no load-minimizes standby drain in always-on medical or metering devices. |
| Snooze Mode IQ | 2 µA typical with output maintained at 3.3 V ±6%-lower than typical battery self-discharge rate. |
| Output Ripple | <5 mVPP at full load-achieved via push-pull topology and eliminates need for post-regulation filtering. |
| Switching Frequency | 200–400 kHz internal; sync-capable up to 800 kHz on SNOOZE pin-enables EMI harmonics placement outside sensitive IF bands. |
Pinout & Package
TPS60210DGS is housed in a 10-pin MSOP (DGS) package-2.0 mm × 3.0 mm, 0.5-mm pitch-with exposed thermal pad (not electrically connected). The package supports tape-and-reel delivery (TPS60210DGSR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI | Low-battery detector input | Accepts resistive divider to set 1.18-V trip threshold; connect to GND if unused-enables system-level battery health monitoring. |
| GND | Ground reference | Primary return path for input, output, and internal circuitry; pin 2 is dedicated ground-critical for ripple suppression and stability. |
| C1−, C1+ | Flying capacitor terminals (Pump 1) | Interface with 1-µF ceramic flying cap; phase-shifted 180° vs C2 to enable continuous output charge transfer. |
| OUT | Regulated 3.3-V output | Supplies load directly; requires ≥2.2-µF ceramic output capacitor (Co) for <5-mVPP ripple and transient response. |
| LBO | Open-drain low-battery warning output | Pulled low when LBI voltage drops below threshold; requires external pullup to OUT or logic rail ≤3.6 V-drives host MCU interrupt or LED. |
| SNOOZE | Mode control and sync input | Low = 2-µA snooze mode; high = normal operation; AC signal = external clock sync-single pin enables three distinct power states. |
| C2−, C2+ | Flying capacitor terminals (Pump 2) | Completes push-pull pair with C1; identical 1-µF requirement-enables ripple cancellation without inductors. |
| IN | Input power supply | Accepts 1.6–3.6 V; bypassed with ≥2.2-µF ceramic capacitor (Ci) close to pin-stabilizes source impedance during charge cycles. |
Key Features
| Feature | Design Value |
|---|---|
| Inductorless architecture | Uses only four ceramic capacitors (C1, C2, Ci, Co)-reduces BOM count, PCB area, and EMI vs inductive DC/DC converters. |
| Push-pull charge-pump topology | Delivers continuous output current with <5-mVPP ripple-eliminates need for post-regulation LDO in noise-sensitive applications. |
| Three-mode SNOOZE control | Supports ultralow-IQ snooze (2 µA), efficient normal operation, and EMI-controlled external sync-enables adaptive power management. |
| Integrated low-battery detector | 1.18-V ±5% threshold on LBI with open-drain LBO output-provides early warning before system brownout without external comparators. |
| Start-up precharge | Connects IN to OUT until VOUT reaches 0.8×VIN-limits inrush into empty Co and ensures reliable cold-start from depleted batteries. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge-pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60211DGS | Replaces LBI/LBO with PG (power-good) output; same 100-mA rating and 3.3-V output. | Used where system startup sequencing or output-voltage validation is required instead of battery monitoring. | Select TPS60211DGS when host MCU needs reliable "output OK" signal rather than low-battery warning. |
| TPS60210DGSR | Identical electrical specs and pinout; R suffix denotes tape-and-reel packaging (3000 units/reel). | No functional difference-used exclusively for automated SMT assembly and volume procurement. | Choose TPS60210DGSR for production builds; TPS60210DGS is for prototyping or low-volume hand-soldering. |
Compared with TPS60211DGS, the TPS60210DGS provides battery health awareness via LBI/LBO but lacks power-good signaling; compared with TPS60210DGSR, it offers identical performance in tube packaging-making TPS60210DGS optimal for evaluation and small-batch integration where reel handling is unnecessary.

FAQ
What is the minimum input voltage required for TPS60210DGS to start up and regulate?
The TPS60210DGS supports startup from 1.6 V, verified across temperature and load conditions. Internal precharge connects IN to OUT until VOUT reaches 0.8×VIN, enabling reliable cold-start even with deeply discharged two-cell alkaline or NiMH batteries. Below 1.6 V, regulation cannot be sustained per datasheet absolute maximum ratings.
Does TPS60210DGS require external compensation components?
No, the TPS60210DGS is fully internally compensated. Its regulation loop is optimized for standard ceramic capacitors: 1 µF for C1/C2, 2.2 µF for Ci and Co. Adding external compensation risks instability and violates the validated design covered in the SLVS296 datasheet typical application circuit.
How does the low-battery detector in TPS60210DGS interface with a microcontroller?
The LBO pin is an open-drain output that pulls low when the LBI voltage drops below 1.18 V. A pullup resistor (100 kΩ–1 MΩ) to OUT or another logic rail ≤3.6 V converts this to an active-low interrupt signal. The TPS60210DGS datasheet Figure 2 shows the resistive divider (R1/R2) connecting VBAT to LBI for threshold programming.
Can TPS60210DGS operate without the SNOOZE pin connected?
Yes-leaving SNOOZE unconnected defaults it to high via internal bias, enabling normal operation mode. However, for lowest quiescent current, explicitly drive SNOOZE low; for EMI control, apply a clean external clock. Floating SNOOZE may cause erratic mode transitions due to noise susceptibility.
What is the maximum output capacitance supported by TPS60210DGS?
The TPS60210DGS supports output capacitors up to 10 µF ceramic (X5R/X7R), as validated in Table 2 of SLVS296. Larger Co improves load transient response and reduces ripple in snooze mode, but exceeding 10 µF may delay startup time or affect stability if ESR falls outside the 0.01–0.1-Ω range recommended for all external capacitors.
