Product details
Overview
TPS60204DGSR from Texas Instruments is a regulated 3.3-V, 100-mA low-ripple charge pump DC/DC converter in a 10-pin MSOP (DGS) package. It operates from 1.6 V to 3.6 V input, delivers <5 mVPP output ripple via push-pull topology, integrates a low-battery detector (LBI/LBO), and supports external clock synchronization - used in battery-powered microprocessor systems and portable medical instruments.
For engineers reviewing the TPS60204DGSR datasheet, TPS60204DGSR pinout, TPS60204DGSR application, or TPS60204DGSR equivalent, key selection criteria include its regulated 3.3-V output with ±4% tolerance, 35-μA quiescent current, 0.05-μA shutdown current, LinSkip mode for light-load efficiency, and explicit low-battery detection functionality (not power-good).
Technical Context
The TPS60204DGSR uses dual single-ended charge pumps operating in 180° push-pull phase to maintain continuous output current and achieve <5 mVPP ripple. Its LinSkip control mode switches seamlessly between constant-frequency linear regulation (>7 mA load) and pulse-skip operation (<7 mA), preserving low ripple while minimizing quiescent current.
It implements an integrated 1.18-V ±4% low-battery comparator referenced to LBI pin, with open-drain LBO output and 10-mV hysteresis. EN pin enables three modes: shutdown (EN = low), internal oscillator (EN = high), or external clock sync (EN = AC signal 400–800 kHz), with automatic disable if EN remains low >10 μs.
Key Specifications

|---|---|
| Output voltage | 3.3 V ±4% (regulated across 1.6–3.6 V input and 0–100 mA load) |
| Max output current | 100 mA continuous (min at 2 V input; peak up to 150 mA per graph) |
| Output ripple | <5 mVPP (measured at 100 mA load with 1-μF flying caps and 2.2-μF output cap) |
| Quiescent current | 35 μA typical (no-load, 1.8–3.6 V input; enables ultra-low-power standby) |
| Shutdown current | 0.05 μA typical (input-output isolation; extends shelf life in battery systems) |
| LBI threshold | 1.18 V ±4% (trip point for low-battery warning; adjustable via external resistor divider) |
| Switching frequency | 200–400 kHz internal; sync capable up to 800 kHz external clock (EN pin) |
Pinout & Package
TPS60204DGSR is housed in a 10-pin MSOP package (DGS), 3.05 mm × 4.98 mm, tape-and-reel (R suffix denotes 2500-unit reel). Pin functions are validated per TI SLVS354B Rev. May 2023.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI | Low-battery detector input | Analog input referenced to internal 1.18-V comparator; connect to battery divider to set custom low-voltage warning threshold |
| GND | Ground reference | Primary ground return for all internal circuits and external capacitors (C1−, C2−, Ci, Co) |
| C1− | Flying capacitor negative terminal | Return node for first flying capacitor (C1); alternates charge/discharge with C1+ during push-pull cycle |
| C1+ | Flying capacitor positive terminal | Charge-transfer node for C1; connected internally to MOSFET switches driving push-pull topology |
| OUT | Regulated output | 3.3-V power rail; requires 2.2-μF ceramic bypass to GND; supplies load and LBO pullup |
| LBO | Open-drain low-battery output | Active-low warning signal; requires external 100-kΩ–1-MΩ pullup to OUT or compatible rail ≤3.6 V |
| EN | Enable/control input | Three-mode control: low = shutdown, high = internal oscillator, AC = external sync (400–800 kHz) |
| C2− | Flying capacitor negative terminal | Return node for second flying capacitor (C2); phased 180° opposite C1− for ripple cancellation |
| IN | Input supply | 1.6–3.6 V battery input; bypassed with 2.2-μF ceramic capacitor to GND |
| C2+ | Flying capacitor positive terminal | Charge-transfer node for C2; complements C1+ in push-pull operation to sustain continuous output current |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull charge pump topology | Enables <5 mVPP output ripple by maintaining continuous current transfer to output capacitor |
| LinSkip mode control | Automatically transitions between constant-frequency regulation (>7 mA) and pulse-skip (<7 mA) to optimize efficiency without sacrificing ripple performance |
| Integrated low-battery detector | 1.18-V ±4% precision comparator with 10-mV hysteresis and open-drain LBO output - no external IC required |
| No-inductor design | Reduces EMI, board space, and BOM cost using only four ceramic capacitors (C1, C2, Ci, Co) |
| Input-output isolation in shutdown | 0.05-μA shutdown current and physical disconnection of IN from OUT prevent battery drain during 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 |
|---|---|---|---|
| TPS60205DGS | Same package, specs, and topology but features power-good (PG) output instead of low-battery (LBO) detection | Used where system startup validation matters more than battery monitoring (e.g., FPGA configuration power rails) | Select TPS60205DGS only if PG functionality is required; not interchangeable with TPS60204DGSR due to different pin mapping (LBI→GND, LBO→PG) and detection logic |
| TPS60122DGS | Higher 200-mA output, same 3.3-V regulation and low-battery detector, but larger 16-pin QFN package and higher quiescent current (55 μA) | Suitable for higher-current portable instrumentation where board space permits larger footprint | Choose TPS60122DGS when >100 mA load or lower thermal resistance is needed; incompatible pinout and layout require PCB redesign |
Compared with TPS60205DGS, TPS60204DGSR provides battery health monitoring instead of power validation; compared with TPS60122DGS, it trades output current and thermal performance for minimal size and ultra-low quiescent current in the compact 10-pin MSOP.

FAQ
What is the exact function of the LBI and LBO pins on the TPS60204DGSR?
The LBI (Low-Battery Input) pin on the TPS60204DGSR accepts a divided battery voltage and compares it to an internal 1.18-V ±4% reference. When the LBI voltage drops below this threshold, the open-drain LBO (Low-Battery Output) pin pulls low to signal battery depletion. LBO requires an external pullup resistor (100 kΩ–1 MΩ) to OUT or another ≤3.6-V rail. If unused, LBI must be tied to GND and LBO left floating.
Does the TPS60204DGSR support external clock synchronization, and what are the valid frequency ranges?
Yes, the TPS60204DGSR supports external clock synchronization via the EN pin. When an AC signal is applied to EN, the device synchronizes its internal switching to half the external clock frequency. Valid external clock frequencies range from 400 kHz to 800 kHz, resulting in internal charge pump operation from 200 kHz to 400 kHz. The device disables if EN remains low for more than 10 μs.
What is the minimum input voltage required for the TPS60204DGSR to deliver full 100-mA output current?
The TPS60204DGSR guarantees 100-mA continuous output current starting at a 2-V input voltage, as specified in the Electrical Characteristics table. Operation is supported down to 1.6 V input, but maximum output current decreases below 2 V - e.g., peak output current drops to ~100 mA at 1.6 V and ~150 mA at 3.6 V per Figure 7-12.
How does the LinSkip mode improve efficiency in the TPS60204DGSR without increasing output ripple?
The TPS60204DGSR's LinSkip mode automatically switches between constant-frequency regulation (>7 mA load) and pulse-skip operation (<7 mA). In pulse-skip mode, the error amplifier disables switching cycles when output voltage exceeds 3.3 V, reducing quiescent current to 35 μA. Crucially, MOSFET rDS(ON) remains actively controlled during active cycles, limiting energy per cycle and maintaining <5 mVPP ripple even at light loads.
Can the TPS60204DGSR be used with input voltages above 3.6 V, and what are the absolute maximum ratings?
No, the TPS60204DGSR must not be operated with input voltage exceeding 3.6 V. Per Absolute Maximum Ratings (Section 7.1), the maximum IN-to-GND voltage is 3.6 V. Exceeding this risks permanent damage. The device is designed for 1.6–3.6 V operation - typical use cases include two alkaline (up to 3.2 V fresh), NiCd, or NiMH cells. Input overvoltage protection is not integrated.
