Product details
Overview
TPS60300DGSR from Texas Instruments is a dual-output, regulated charge pump DC-DC converter designed for space-constrained, single-cell battery-powered systems. It accepts 0.9 V to 1.8 V input (e.g., one alkaline/NiMH cell), delivers regulated 3.3 V ±4% at up to 20 mA on OUT2 and 2×VIN (up to 40 mA) on OUT1, and features open-drain power-good supervision - used in portable medical instruments and smart card readers.
For engineers reviewing the TPS60300DGSR datasheet, TPS60300DGSR pinout, TPS60300DGSR application, or TPS60300DGSR equivalent, key selection criteria include its 10-pin VSSOP package, LinSkip mode for light-load efficiency, shutdown current <2.5 µA, 90% peak conversion efficiency, and compatibility with five 1-µF ceramic capacitors only - no inductors required.
Technical Context
The TPS60300DGSR implements a two-stage switched-capacitor architecture: first stage doubles VIN to generate OUT1; second stage quadruples VIN (or regulates 3.3 V from 0.9–1.8 V) to produce OUT2. It automatically selects between 3× or 4× conversion modes based on input voltage to maintain regulation across the full 0.9–1.8 V range.
Its LinSkip operating mode transitions seamlessly between pulse-skipping (for <7.5 mA load) and constant-frequency linear-regulation (for higher loads), minimizing output ripple while sustaining >90% efficiency at 20 mA. The open-drain PG pin monitors OUT2 and asserts high when voltage reaches ≥98% of nominal 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.9 V to 1.8 V - supports single alkaline, NiCd, or NiMH cell without brownout across full discharge curve. |
| OUT2 Output Voltage | 3.3 V ±4% - tightly regulated rail for MCU I/O or analog circuitry requiring stable 3.3-V supply. |
| Max Output Current (OUT2) | 20 mA - sufficient for low-power MSP430 peripherals, hearing instrument ASICs, or pager logic. |
| Quiescent Current | <35 µA - enables multi-year battery life in always-on portable instrumentation. |
| Switching Frequency | 470–900 kHz - high-frequency operation allows use of small 1-µF ceramic flying/output capacitors. |
| Shutdown Current | 0.05 µA - isolates load from battery during sleep, preserving shelf life in home-automation sensors. |
| Power-Good Output | Open-drain PG - provides system reset or enable sequencing signal when OUT2 reaches regulation. |
Pinout & Package
TPS60300DGSR is housed in a micro-small 10-pin VSSOP (DGS) package measuring 3.05 mm × 4.98 mm, optimized for high-density PCB layouts in portable devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high digital control: drives device into ultra-low-IQ shutdown (<0.05 µA) when pulled low. |
| VIN | Input supply | Accepts 0.9–1.8 V battery source; requires ≥1-µF ceramic bypass capacitor to GND for stability. |
| C1+, C1− | Flying capacitor 1 terminals | Form first charge-pump stage; connect to 1-µF ceramic capacitor (C1F) for voltage doubling to OUT1. |
| OUT1 | Unregulated 2×VIN output | Delivers up to 40 mA at ~2×VIN; used for bias rails or auxiliary supplies where regulation not critical. |
| OUT2 | Regulated 3.3-V output | Main regulated rail; 3.3 V ±4% over temperature and load; bypassed with 1-µF ceramic capacitor. |
| PG | Power-good indicator | Open-drain output asserting high when OUT2 ≥98% of 3.3 V; requires external pull-up to OUT1 or OUT2. |
| GND | Ground reference | Common return for all internal circuits and external capacitors; must be low-impedance plane. |
| C2+, C2− | Flying capacitor 2 terminals | Form second charge-pump stage; connect to 1-µF ceramic capacitor (C2F) for regulated 3.3-V generation. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor design | Enables complete DC-DC solution with only five 1-µF ceramic capacitors - eliminates EMI, size, and cost penalties of magnetics. |
| LinSkip mode | Automatically switches between pulse-skipping (low IQ) and constant-frequency linear regulation - maintains low noise and high efficiency across 0–20 mA load. |
| Load isolation in shutdown | Disconnects OUT1/OUT2 from VIN when EN = low - prevents battery drain in storage or standby, extending shelf life. |
| Integrated power-good supervisor | Monitors OUT2 regulation in real time and signals system controller via open-drain PG - enables safe power-up sequencing and fault detection. |
| Wide input voltage support | Operates down to 0.9 V input - supports full discharge of alkaline cells (2000 mAh) until power-good deasserts at IL = 20 mA. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60302DGSR | Same pinout and package; push-pull PG output instead of open-drain - eliminates need for external pull-up resistor. | Preferred where system lacks dedicated pull-up rail; reduces BOM count but increases PG output loading on OUT2. | Select TPS60302DGSR if PG drive strength >1.6 mA is needed and OUT2 loading margin permits. |
| MAX680ESA+ | Single-output 5-V charge pump; no OUT1 doubler, no PG, wider input (1.5–6.5 V); SO-8 package. | Suitable only for 5-V-only systems; lacks dual-rail capability and supervision - cannot replace TPS60300DGSR directly. | Consider MAX680ESA+ only for legacy 5-V designs where 3.3-V regulation and PG are unnecessary. |
Compared with TPS60302DGSR, TPS60300DGSR offers simpler PG interface (open-drain) with lower output loading impact; compared with MAX680ESA+, it delivers dual regulated/unregulated outputs, tighter 3.3-V tolerance, and integrated power supervision - making it uniquely suited for modern low-voltage portable instrumentation.

FAQ
What is the input voltage range supported by the TPS60300DGSR?
The TPS60300DGSR supports an input voltage range of 0.9 V to 1.8 V, enabling direct operation from a single alkaline, NiCd, or NiMH cell across its full discharge curve. This range is validated per TI SLVS302B datasheet Section 8.3, with guaranteed regulation on OUT2 down to 0.9 V at reduced load (10 mA).
Does the TPS60300DGSR require external inductors?
No, the TPS60300DGSR is a switched-capacitor charge pump and requires no inductors. It operates with only five 1-µF ceramic capacitors - CIN, C1F, C2F, COUT1, and COUT2 - as specified in the Typical Application Schematic (Section 10.2) and Feature list of the SLVS302B datasheet.
What is the function of the PG pin on the TPS60300DGSR?
The PG (power-good) pin on the TPS60300DGSR is an open-drain output that goes high when the OUT2 voltage reaches ≥98% of its nominal 3.3 V value. As stated in Section 9.3.1, it requires an external pull-up resistor (100 kΩ to 1 MΩ) to OUT1 or OUT2 and is used for system power-up sequencing and fault monitoring.
What is the maximum output current capability of the TPS60300DGSR on OUT2?
The TPS60300DGSR delivers up to 20 mA on OUT2 when VIN ≥1.1 V and OUT1 is unloaded, as confirmed in Section 8.5 Electrical Characteristics (IOUT(OUT2) row). At VIN = 0.9 V, maximum OUT2 current is 10 mA - a derating necessary to maintain regulation under low-input conditions.
How does the TPS60300DGSR achieve high efficiency across varying loads?
The TPS60300DGSR uses LinSkip mode - a proprietary operating mode that automatically transitions between pulse-skipping (for light loads <7.5 mA) and constant-frequency linear regulation (for heavier loads). This preserves >90% peak efficiency while minimizing output ripple, as detailed in Section 5 Description and Figure 7 Efficiency vs Output Current.
