Product details
Overview
TPS60300DGS from Texas Instruments is a dual-output, regulated charge pump DC-DC converter designed for space-constrained, single-cell battery-powered systems. It delivers 40 mA at 2×VIN (OUT1) and 20 mA at regulated 3.3 V ±4% (OUT2), with input voltage range 0.9 V–1.8 V, quiescent current <35 µA, and up to 90% power conversion efficiency - enabling long runtime in hearing instruments and portable smart card readers.
For engineers reviewing the TPS60300DGS datasheet, TPS60300DGS pinout, TPS60300DGS application, or TPS60300DGS equivalent, this page provides verified technical context, exact pin functions, real-world operating constraints (e.g., LinSkip mode transition at 7.5 mA, 400 µs no-load start-up), and validated alternatives for 3.3-V dual-output charge pump replacement in ultra-low-voltage, low-noise embedded designs.
Technical Context
The TPS60300DGS implements a two-stage switched-capacitor architecture: first stage doubles VIN to generate OUT1 (2×VIN), second stage quadruples and regulates to fixed 3.3 V on OUT2. It automatically selects between 3× or 4× conversion modes based on input voltage to maintain regulation across 0.9 V–1.8 V.
It operates in LinSkip mode - seamlessly transitioning from pulse-skipping (low IQ) at light loads to constant-frequency linear-regulation above 7.5 mA - and integrates an open-drain power-good (PG) comparator that asserts high when OUT2 reaches ≥98% of nominal voltage, with hysteresis of 10%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.9 V to 1.8 V - supports single alkaline/NiMH/NiCd cell without brownout across full discharge curve. |
| OUT2 Output Voltage | 3.3 V ±4% - tightly regulated rail for 3.3-V logic, ADC references, or RF front-end biasing. |
| Max Output Current | 40 mA on OUT1 (2×VIN), 20 mA on OUT2 - enables concurrent powering of analog and digital subsystems. |
| Quiescent Current | <35 µA - extends shelf life and runtime in always-on, intermittently active devices like pagers. |
| Switching Frequency | 470–900 kHz - allows use of small 1-µF ceramic capacitors; avoids audible noise and EMI in sensitive audio applications. |
| Power-Good Output | Open-drain PG with 98% trip threshold - enables reliable power sequencing and system reset control. |
| Shutdown Current | 0.05 µA - isolates load from battery during sleep, minimizing self-discharge in medical wearables. |
Pinout & Package
TPS60300DGS uses a 10-pin VSSOP (DGS) package measuring 3.05 mm × 4.98 mm, optimized for high-density PCB layouts in portable instrumentation and hearing aids.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control; pulls device into 0.05 µA shutdown state when low, isolating battery from outputs. |
| VIN | Supply input | Accepts 0.9–1.8 V single-cell source; requires ≥1-µF bypass capacitor to stabilize input impedance. |
| OUT1 | Unregulated 2×VIN output | Delivers up to 40 mA; used for analog rails or as intermediate supply for second-stage regulation. |
| OUT2 | Regulated 3.3-V output | Provides 20 mA at ±4% accuracy; powers 3.3-V microcontrollers, sensors, or communication ICs. |
| PG | Power-good indicator | Open-drain output asserting high when OUT2 ≥3.234 V; requires external pull-up (100 kΩ–1 MΩ) to OUT1 or OUT2. |
| C1+, C1−, C2+, C2− | Flying capacitor terminals | Interface with four 1-µF ceramic flying caps; topology enables inductorless voltage doubling and quadrupling. |
| GND | Ground reference | Common return for all internal circuits and external capacitors; must be low-impedance plane for ripple suppression. |
Key Features
| Feature | Design Value |
|---|---|
| LinSkip operating mode | Seamlessly transitions from pulse-skipping (≤7.5 mA) to constant-frequency linear regulation (>7.5 mA), optimizing efficiency and noise simultaneously. |
| No-inductor design | Relies solely on five 1-µF ceramic capacitors - eliminates magnetic EMI, reduces BOM cost, and simplifies layout in size-constrained devices. |
| Battery isolation in shutdown | Load disconnection from VIN during EN = low reduces leakage to ≤1 µA, preserving battery shelf life for >1 year in storage. |
| Integrated power-good supervision | Monitors OUT2 regulation in real time and signals readiness via open-drain PG - eliminates need for external supervisor IC. |
| Wide input compatibility | Operates down to 0.9 V input - supports full discharge of alkaline, NiMH, and NiCd cells without requiring boost pre-regulator. |
Applications
| Portable Hearing Instruments | Pagers & Low-Power Wearables |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60302DGS | Identical pinout and electrical specs, but push-pull PG output (no external pull-up required) and same 3.3-V OUT2 regulation. | Eliminates need for external pull-up resistor; better suited for systems where PG drives logic directly without level translation. | Select TPS60302DGS if board layout lacks space for 100-kΩ pull-up or if PG must drive CMOS inputs without additional components. |
| TPS60310DGS | Same VSSOP-10 package, 3.3-V OUT2, but higher 50-mA OUT2 current capability and 1.5-MHz switching frequency. | Supports higher-current peripherals (e.g., Bluetooth LE radios); requires smaller 0.47-µF flying caps due to faster switching. | Choose TPS60310DGS only when >20 mA OUT2 load is required and layout can accommodate tighter capacitor placement for 1.5-MHz operation. |
Compared with TPS60300DGS, TPS60302DGS removes external component dependency for PG interfacing while retaining identical regulation and efficiency, whereas TPS60310DGS trades higher quiescent current (65 µA) for increased output capability and faster transient response - making it suitable only for higher-power variants of the same application space.

FAQ
What is the maximum output current capability of TPS60300DGS on each rail?
The TPS60300DGS delivers up to 40 mA on OUT1 (2×VIN) when OUT2 is unloaded, and up to 20 mA on OUT2 (3.3 V) when OUT1 is unloaded. Simultaneous loading is permitted, but total current drawn from the first charge pump stage must not exceed 40 mA - for example, 20 mA on OUT1 and 10 mA on OUT2 is valid. This constraint ensures stable regulation and thermal performance within the VSSOP package.
Does TPS60300DGS require external inductors?
No, the TPS60300DGS is an inductorless charge pump converter. It uses only five 1-µF ceramic capacitors - one input (CIN), two flying (C1F, C2F), and two output (COUT1, COUT2) - to achieve voltage doubling and regulation. This eliminates magnetic EMI, reduces solution size, and lowers BOM cost compared to inductive DC-DC solutions.
How does the power-good (PG) output function on TPS60300DGS?
The TPS60300DGS features an open-drain PG output that goes high when OUT2 reaches ≥98% of its nominal 3.3-V value (≥3.234 V), with 10% hysteresis. It requires an external pull-up resistor (100 kΩ–1 MΩ) to either OUT1 or OUT2. During shutdown (EN = low), PG is actively pulled low - enabling reliable power sequencing and system reset control in portable designs.
What is the minimum input voltage required for TPS60300DGS to regulate 3.3 V on OUT2 at full 20 mA load?
At 20 mA load on OUT2, the TPS60300DGS requires a minimum input voltage of 1.1 V to maintain regulation. Below 1.1 V, output voltage drops - e.g., at 0.9 V input, regulation holds only up to 10 mA on OUT2. This behavior is documented in the Electrical Characteristics table and ensures compatibility with fully discharged alkaline and NiMH cells.
Can TPS60300DGS operate in shutdown mode with zero load and still isolate the battery?
Yes. When EN is driven low, the TPS60300DGS enters shutdown mode with typical supply current of 0.05 µA and output leakage ≤1 µA per rail. This true load isolation prevents battery drain during storage or standby, supporting >1-year shelf life in hearing instruments and other sealed portable devices - a key requirement confirmed in the device functional modes section.
