Product details
Overview
TPS60212DGSR from Texas Instruments is a regulated 3.3-V step-up charge pump DC/DC converter for battery-powered systems, delivering up to 50 mA continuous output current from 1.6–3.6 V input, featuring ultra-low 2 µA snooze-mode quiescent current, <5-mVPP output ripple via push-pull topology, and integrated low-battery detection. It replaces inductor-based converters in space-constrained medical and portable electronics.
For engineers reviewing the TPS60212DGSR datasheet, TPS60212DGSR pinout, TPS60212DGSR application, or TPS60212DGSR equivalent, key selection criteria include its 50-mA output capability at 2-V input, 10-pin MSOP (DGS) package, low-battery detector with 1.18-V threshold, linskip mode transition at ~7 mA, and compatibility with ceramic-only external capacitor design (C1/C2 = 1 µF, Ci/Co = 2.2 µF).
Technical Context
The TPS60212DGSR implements dual single-ended charge pumps operating in 180° push-pull phase to ensure continuous charge transfer and minimize output voltage ripple. Its regulation uses a combination of constant-frequency linear-regulation mode above ~7 mA load and pulse-skip mode below that threshold-enabling high efficiency across wide load ranges while maintaining tight ±4% output voltage accuracy.
Three operational modes are controlled via the SNOOZE pin: low-power snooze mode (2 µA IQ, 2 mA max load), normal operation (internal 200–400 kHz oscillator), or external clock synchronization (400–800 kHz). The device integrates a precision low-battery comparator (trip = 1.18 V ±5%) with open-drain LBO output and supports start-up precharge to 0.8×VIN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% over 1.6–3.6 V input and 0–50 mA load - ensures stable supply for 3.3-V logic without external LDO. |
| Max Output Current | 50 mA minimum at 2-V input - sufficient for MSP430 microcontrollers and glucose meter sensors. |
| Quiescent Current | 35 µA typical no-load, 2 µA in snooze mode - extends shelf life and runtime in always-on battery devices. |
| Output Ripple | <5 mVPP at full load - eliminates need for post-regulation filtering in noise-sensitive analog circuits. |
| Switching Frequency | 200–400 kHz internal, syncable to 400–800 kHz external clock - enables EMI control in RF-sensitive designs. |
| Low-Battery Threshold | 1.18 V ±5% on LBI pin - configurable via resistive divider for precise battery end-of-life signaling. |
| Package | 10-pin MSOP (DGS), 3.0 × 3.0 × 1.0 mm - compact footprint compatible with high-density portable PCB layouts. |
Pinout & Package
TPS60212DGSR is housed in a 10-pin MSOP (DGS) package with exposed thermal pad (not electrically connected). Pin numbering follows standard DGS layout: top view, pin 1 at top-left corner, counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI | Low-battery detector input | Accepts voltage divider from battery; triggers LBO when ≤1.18 V - enables user-defined battery depletion warning. |
| GND | Ground reference (pins 2 and ?) | Dual GND pins (2 and ?) reduce ground impedance and improve thermal dissipation in high-current transients. |
| C1−, C1+ | Flying capacitor terminals (1st pump) | Connect 1-µF ceramic flying cap; polarity critical - reverse connection causes failure or excessive ripple. |
| C2−, C2+ | Flying capacitor terminals (2nd pump) | Second flying cap operates 180° out-of-phase with C1 - enables push-pull charge transfer and ripple cancellation. |
| OUT | Regulated 3.3-V output | Supplies load directly; requires ≥2.2-µF ceramic bypass to GND for stability and transient response. |
| LBO | Open-drain low-battery output | Pulled low when LBI <1.18 V; requires external pullup to OUT or logic rail ≤3.6 V - drives MCU interrupt or LED. |
| SNOOZE | Mode control input | Low = snooze (2 µA IQ); high = normal (internal oscillator); AC signal = external sync - single-pin multimode control. |
| IN | Input power supply | Accepts 1.6–3.6 V; bypassed with ≥2.2-µF ceramic cap to suppress source impedance and improve efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Inductorless architecture | Eliminates magnetic components and associated EMI - simplifies layout, reduces BOM cost, and improves reliability in portable devices. |
| Push-pull charge pump topology | Two 180°-phase-shifted pumps deliver continuous charge flow - achieves <5-mVPP ripple without LC filtering. |
| Linskip adaptive regulation | Seamlessly transitions between constant-frequency (low-noise) and pulse-skip (high-efficiency) modes at ~7 mA - optimizes performance across dynamic loads. |
| Integrated low-battery detector | 1.18-V ±5% comparator with open-drain LBO output - provides accurate, programmable battery monitoring without external ICs. |
| Snooze mode with 2-µA IQ | Maintains 3.3-V output within ±6% while drawing less than typical battery self-discharge current - ideal for long-term storage. |

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 | 100-mA output rating, same 3.3-V regulation and DGS package - higher current capability with identical pinout and feature set. | Required where peak load exceeds 50 mA (e.g., active RF transmission bursts or multi-sensor concurrent sampling). | Select TPS60210DGSR when system peak current >50 mA; otherwise TPS60212DGSR offers lower quiescent current in light-load scenarios. |
| MAX860ESA+ | 3.3-V fixed-output charge pump (50 mA), 8-pin SOIC package, no snooze mode or low-battery detection - simpler but less feature-rich. | Suitable for cost-sensitive, non-critical applications lacking battery monitoring or ultra-low-power sleep requirements. | Choose MAX860ESA+ only if board space permits larger SOIC and features like LBI/LBO or 2-µA snooze are unnecessary. |
Compared with TPS60210DGSR, the TPS60212DGSR trades 50-mA output headroom for tighter integration of low-battery monitoring and deeper sleep efficiency; versus MAX860ESA+, it adds critical system-level supervision functions at the cost of slightly higher complexity and pin count.

FAQ
What is the maximum continuous output current of the TPS60212DGSR?
The TPS60212DGSR delivers a minimum of 50 mA continuous output current when supplied from a 2-V input, as specified in the SLVS296 datasheet. This rating holds across the full operating temperature range (−40°C to 85°C) and input voltage range (1.6 V to 3.6 V), making the TPS60212DGSR suitable for moderate-power portable electronics such as glucose meters and sensor nodes where peak loads remain within this limit.
Does the TPS60212DGSR require inductors in its application circuit?
No, the TPS60212DGSR is an inductorless charge pump DC/DC converter. It uses two flying capacitors (C1 and C2, typically 1 µF each) and input/output ceramic capacitors (Ci and Co, minimum 2.2 µF) to generate a regulated 3.3-V output. This eliminates magnetic components, reduces EMI, saves PCB area, and lowers BOM cost - a core design advantage of the TPS60212DGSR over traditional boost converters.
How does the snooze mode function in the TPS60212DGSR?
When the SNOOZE pin is driven low, the TPS60212DGSR enters snooze mode, reducing quiescent current to a typical 2 µA while maintaining output regulation within 3.3 V ±6%. Load current is limited to 2 mA in this mode. If load exceeds 2 mA, the device automatically exits snooze to restore full regulation - a behavior confirmed in the SLVS296 functional description and electrical characteristics tables for the TPS60212DGSR.
What is the purpose of the LBI and LBO pins on the TPS60212DGSR?
The LBI (Low-Battery Input) and LBO (Low-Battery Output) pins implement an integrated battery monitoring function unique to the TPS60212DGSR. LBI accepts a resistive divider from the battery to set a trip point (typically 1.18 V); when voltage falls below threshold, LBO - an open-drain output - pulls low to signal MCU or alert circuitry. This eliminates need for external comparators in battery-powered designs using the TPS60212DGSR.
Can the TPS60212DGSR be synchronized to an external clock signal?
Yes, the TPS60212DGSR supports external clock synchronization via the SNOOZE pin. When an AC signal (400–800 kHz, 30–70% duty cycle) is applied, the internal switching frequency locks to half the input clock frequency. This capability enables EMI reduction by aligning switching harmonics away from sensitive bands - a documented feature of the TPS60212DGSR in the SLVS296 datasheet's "Synchronization to an External Clock Signal" section.
