Product details
Overview
TPS60200DGSR from Texas Instruments is a regulated 3.3 V, 100-mA charge pump DC/DC converter for battery-powered systems operating from 1.6 V to 3.6 V input. It uses push-pull topology with four external ceramic capacitors, delivers <5 mVPP output ripple, and integrates a low-battery detector (LBI/LBO) for two-cell alkaline/NiMH systems in portable medical devices and audio players.
For engineers reviewing the TPS60200DGSR datasheet, TPS60200DGSR pinout, TPS60200DGSR application, or TPS60200DGSR equivalent, key selection criteria include its 100 mA regulated output at 3.3 V, 35 µA quiescent current, 0.05 µA shutdown current, MSOP-10 package, and integrated low-battery warning functionality with 1.18 V threshold.
Technical Context
The TPS60200DGSR implements dual single-ended charge pumps operating in 180° phase-shifted push-pull mode to sustain continuous output current and minimize ripple. Regulation is achieved via error amplifier-controlled MOSFET gate drive in constant-frequency mode above 7 mA load, switching seamlessly to pulse-skip mode below that threshold.
It features an internal 1.18 V reference for the low-battery comparator, auto-discharge of the output capacitor during shutdown, and EN pin dual-function operation-enabling internal oscillator, disabling device, or synchronizing to external clock up to 800 kHz. Input voltage range extends down to 1.6 V for deep battery discharge support.

Pinout & Package
TPS60200DGSR is housed in a 10-pin MSOP (DGS) package measuring 3.00 mm × 3.00 mm with exposed thermal pad (not electrically connected). The package supports fine-pitch PCB assembly and provides adequate thermal dissipation (RθJA = 158.1°C/W) for 100 mA operation in ambient temperatures up to 85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - LBI | Low-battery detector input | Analog input referenced to GND; triggers LBO when voltage falls below 1.18 V - used to monitor battery voltage via resistive divider |
| 2, 3 - GND | Ground terminals | Dual ground pins reduce ground impedance and improve PSRR; must be tied to common system ground plane |
| 4 - C1+ | Flying capacitor positive terminal | Connects to + terminal of 1 µF ceramic flying capacitor C1 - critical path for charge transfer timing and efficiency |
| 5 - OUT | Regulated 3.3 V output | Primary power rail; requires 2.2 µF ceramic output capacitor (Co) to maintain ripple & transient performance |
| 6 - C2+ | Flying capacitor positive terminal | Connects to + terminal of second 1 µF flying capacitor C2 - completes push-pull charge transfer cycle with C1 |
| 7 - IN | Input supply | Accepts 1.6–3.6 V battery input; bypassed with 2.2 µF ceramic capacitor (Ci) close to pin for stability and EMI reduction |
| 8 - C2− | Flying capacitor negative terminal | Connects to − terminal of C2; forms complementary half of push-pull pumping stage |
| 9 - EN | Enable/synchronization input | Three-state control: low = shutdown, high = internal oscillator, AC signal = external clock sync up to 800 kHz |
| 10 - LBO | Open-drain low-battery output | Pulled low when LBI < 1.18 V; requires external pullup (100 kΩ–1 MΩ) to OUT or compatible rail for logic-level signaling |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull charge pump topology | Enables continuous current delivery and <5 mVPP ripple without inductors - eliminates EMI and size penalties of buck/boost converters |
| Integrated low-battery detector | 1.18 V ±4% precision threshold with hysteresis - enables reliable battery end-of-life signaling without external comparators or references |
| Auto-discharge on shutdown | Active discharge of output capacitor within 0.6 ms when EN goes low - ensures safe, predictable system power-down state |
| Ultra-low quiescent and shutdown currents | 35 µA operating / 0.05 µA shutdown - extends runtime in intermittent-use devices like handheld test equipment and wearables |
| External clock synchronization | EN pin accepts 400–800 kHz clock signal - allows EMI frequency steering and system-level timing coordination |
| Four-capacitor solution | Only Ci, C1, C2, and Co required - reduces BOM count, PCB area, and design complexity versus multi-inductor alternatives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60122DR | Same 3.3 V/100 mA output, but higher 200 mA peak current rating and 90% efficiency vs. 85% typical for TPS60200DGSR | Targeted at higher-pulse-load applications (e.g., wireless transceivers); lacks LBO open-drain structure - uses active-high PG | Select TPS60122DR if peak current >100 mA or higher efficiency at light loads is required; verify LBO replacement with external logic if low-active signaling is mandatory |
| TPS60201DGSR | Pin-compatible MSOP-10 variant with power-good (PG) instead of low-battery (LBO) output; identical electrical specs otherwise | Used where system-level power sequencing requires "power OK" confirmation rather than battery depletion warning | Choose TPS60201DGSR only if power-good assertion (not low-battery alert) aligns with host controller requirements; no change to layout or external components needed |
Compared with TPS60122DR and TPS60201DGSR, the TPS60200DGSR uniquely provides open-drain low-battery signaling with 1.18 V threshold in a minimal 4-capacitor configuration - making it optimal for cost-sensitive, space-constrained battery monitors where end-of-life detection drives user interaction.

FAQ
What is the minimum input voltage supported by the TPS60200DGSR?
The TPS60200DGSR operates down to 1.6 V input, enabling full utilization of two alkaline, NiCd, or NiMH cells through deep discharge. Below this voltage, regulation is not guaranteed and output may drop out. This 1.6 V minimum supports extended runtime in battery-powered applications such as handheld medical instruments and portable audio devices where every millivolt of battery capacity matters.
Does the TPS60200DGSR require an inductor?
No, the TPS60200DGSR is a capacitor-based charge pump and requires no inductor. It uses two 1 µF flying capacitors (C1, C2), a 2.2 µF input capacitor (Ci), and a 2.2 µF output capacitor (Co) - all ceramic X5R/X7R types. This inductorless architecture eliminates magnetic EMI, reduces board area, and simplifies layout compared to inductive DC/DC converters, making it ideal for noise-sensitive and space-constrained designs.
How does the low-battery detection work on the TPS60200DGSR?
The TPS60200DGSR features a precision 1.18 V ±4% low-battery comparator referenced to GND on the LBI pin. When the voltage at LBI drops below this threshold - typically set via a resistor divider from the battery - the open-drain LBO pin pulls low. An external pullup resistor (100 kΩ–1 MΩ) to OUT or another logic rail generates a clean logic-low signal for host MCU interrupt or display alert, enabling timely user notification before system brownout.
Can the TPS60200DGSR be synchronized to an external clock?
Yes, the TPS60200DGSR supports external clock synchronization via the EN pin. Applying a 400–800 kHz square wave (30–70% duty cycle) to EN configures the device to run at half that frequency (200–400 kHz), allowing EMI frequency steering and system-level timing alignment. If EN is held high DC, the device uses its internal oscillator; if pulled low, it enters 0.05 µA shutdown with output capacitor auto-discharge.
What is the output voltage ripple specification for the TPS60200DGSR?
The TPS60200DGSR delivers less than 5 mVPP output voltage ripple under maximum 100 mA load, achieved through its push-pull charge pump topology and optimized capacitor selection (1 µF flying, 2.2 µF output). This low ripple eliminates need for post-regulation LDOs in many applications, preserving efficiency while meeting noise requirements for precision analog circuits, ADCs, and RF receivers in portable equipment.
