Product details
Overview
TPS60204DGS from Texas Instruments is a regulated 3.3-V, 100-mA charge pump DC/DC converter in a 10-pin MSOP (DGS) package, designed for low-ripple, inductorless power conversion from 1.6-V to 3.6-V inputs-ideal for two-cell alkaline/NiMH battery systems in portable medical and audio devices.
For engineers reviewing the TPS60204DGS datasheet, TPS60204DGS pinout, TPS60204DGS application, or TPS60204DGS equivalent, key selection criteria include its 5-mVPP output ripple, LinSkip mode enabling 35-μA quiescent current, integrated low-battery detector with 1.18-V threshold, push-pull topology, and EN pin programmable operation (shutdown/sync/internal oscillator).
Technical Context
The TPS60204DGS implements a dual single-ended charge pump in push-pull phase (180°), delivering regulated 3.3 V ±4% across 1.6–3.6 V input while maintaining continuous current transfer to minimize ripple. Its LinSkip control seamlessly transitions between constant-frequency linear regulation (>7 mA load) and pulse-skip mode (<7 mA) to optimize efficiency and noise.
It integrates a 1.18-V reference, error amplifier, shutdown/start-up circuit, and low-battery comparator with open-drain LBO output. The EN pin serves triple function: logic-level enable, external clock sync input (400–800 kHz), and oscillator disable-enabling precise EMI management and battery isolation during shutdown (0.05-μA ISD).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 3.3 V ±4% - tightly regulated rail for 3.3-V logic and analog circuits without external feedback resistors |
| Max output current | 100 mA continuous - sufficient for microprocessor cores, sensors, and RF front-ends in compact battery-powered systems |
| Input voltage range | 1.6 V to 3.6 V - supports full discharge of two alkaline/NiMH cells (1.0 V/cell) while maintaining regulation |
| Output ripple | <5 mVPP - achieved via push-pull topology and optimized capacitor layout; eliminates need for post-regulation LDO in noise-sensitive applications |
| Quiescent current | 35 μA - enables multi-year shelf life in always-on portable instrumentation with minimal standby drain |
| Shutdown current | 0.05 μA - isolates battery from load during deep sleep, critical for glucose meters and emergency wearables |
| Low-battery threshold | 1.18 V ±4% on LBI pin - user-configurable via resistor divider to signal end-of-life before system brownout |
Pinout & Package
TPS60204DGS is housed in a 3.05 mm × 4.98 mm 10-pin MSOP (DGS) package, tape-and-reel compatible (R-suffix variant available). Pin functions are validated per TI SLVS354B Rev. May 2023.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBI | Low-battery detector input | Accepts voltage divider from battery; triggers LBO when ≤1.18 V; must be tied to GND if unused |
| GND | Power ground | Dual GND pins (2 & 10 in functional diagram) provide low-impedance return path for flying capacitors and output stage |
| C1−, C1+ | Flying capacitor terminals (C1) | Form first half of push-pull charge pump; require 1-μF X7R ceramic (low ESR) for 100-mA operation |
| OUT | Regulated 3.3-V output | Delivers up to 100 mA; bypassed with 2.2-μF ceramic capacitor to GND for ripple suppression and transient response |
| 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; invalid for first 500 μs at startup |
| EN | Enable/sync control input | Three-mode: Low = shutdown (0.05 μA); High = internal oscillator; AC-coupled clock = sync (400–800 kHz) |
| C2−, C2+ | Flying capacitor terminals (C2) | Second half of push-pull pair; phased 180° from C1 to sustain continuous output current and minimize ripple |
| IN | Input supply | Accepts 1.6–3.6 V; bypassed with 2.2-μF ceramic capacitor to GND near pin for stable input impedance |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull charge pump topology | Enables continuous current delivery to output capacitor, achieving <5-mVPP ripple without inductors or post-LDO filtering |
| LinSkip operating mode | Automatically switches between constant-frequency regulation (>7 mA) and pulse-skip (<7 mA), sustaining 35-μA IQ at light loads |
| Integrated low-battery detector | 1.18-V ±4% threshold with hysteresis; provides early warning before system reset, configurable via external R-divider |
| EN pin multifunctionality | Single pin controls shutdown, internal oscillation, or external clock synchronization-reducing BOM count and PCB routing complexity |
| Ultrasmall MSOP-10 package | 3.05 mm × 4.98 mm footprint with only four external ceramic capacitors required-ideal for space-constrained handheld instruments |

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, pinout, and electrical specs-but features power-good (PG) output instead of low-battery (LBO) detector | Used where system monitoring requires confirmation of valid 3.3-V output (e.g., FPGA configuration sequencing), not battery health | Select TPS60205DGS when power-good signaling is needed; otherwise, TPS60204DGS is optimal for battery-aware designs |
| TPS60122DGS | Higher 200-mA output, same 3.3-V regulation, but uses different LinSkip threshold (10 mA) and lacks EN sync capability | Suitable for higher-current peripherals (e.g., Bluetooth radios), but less suitable for ultra-low-power standby due to higher IQ (55 μA) | Choose TPS60122DGS only if >100 mA is required; TPS60204DGS offers superior efficiency below 100 mA and tighter ripple control |
Compared with TPS60205DGS, TPS60204DGS provides battery-end-of-life signaling instead of power validation-critical for portable medical devices. Against TPS60122DGS, it trades peak current for lower quiescent consumption and enhanced ripple performance, making it preferable for long-life, noise-sensitive applications.

FAQ
What is the minimum input voltage supported by the TPS60204DGS?
The TPS60204DGS operates down to 1.6 V input, enabling full utilization of two alkaline or NiMH cells through end-of-discharge. Below 1.6 V, regulation is not guaranteed; the device may continue switching but output voltage will drop outside ±4% tolerance. This 1.6-V minimum supports typical two-cell battery discharge curves where usable capacity extends below 1.8 V.
How does the LinSkip mode improve efficiency in the TPS60204DGS?
The TPS60204DGS enters LinSkip mode below ~7 mA load, disabling switching cycles until output voltage drops below 3.3 V. This reduces average switching losses and cuts quiescent current to 35 μA-nearly 5× lower than constant-frequency mode. Each active cycle transfers only the energy needed to sustain regulation, minimizing ripple while maximizing battery life in standby.
Can the TPS60204DGS be synchronized to an external clock, and what are the limits?
Yes-the EN pin accepts an external clock signal (400–800 kHz, 30–70% duty cycle) to synchronize switching. Internal charge pump frequency is half the EN clock rate (e.g., 600-kHz EN → 300-kHz fOSC). If EN remains low >10 μs, the device shuts down. This feature enables EMI reduction by aligning harmonics away from sensitive bands like 455-kHz IF stages.
What capacitor values are required for full 100-mA operation of the TPS60204DGS?
For 100-mA continuous output, TI specifies 1-μF X7R/X5R ceramic flying capacitors (C1, C2), 2.2-μF input capacitor (Ci), and 2.2-μF output capacitor (Co)-all placed close to respective pins. Using smaller values (e.g., 0.47 μF) reduces max output current and raises ripple; larger Co (e.g., 10 μF) improves transient response but adds size and cost without benefit at 100 mA.
Is the TPS60204DGS pin-compatible with other devices in the TPS6020x family?
Yes-TPS60204DGS and TPS60205DGS share identical 10-pin MSOP (DGS) package, pinout, and core electrical specifications. They differ only in monitor function: TPS60204DGS has LBI/LBO (low-battery), while TPS60205DGS has GND/PG (power-good). No PCB changes are needed when swapping between them, provided the system's monitoring requirement matches the selected variant.
