Product details
Overview
TPS60301DGS from Texas Instruments is a dual-output, regulated charge pump DC-DC converter designed for space-constrained, single-cell battery-powered systems. It delivers a stable 3-V ±4% output (OUT2) and a 2×VIN unregulated output (OUT1), supports 0.9–1.8-V input, provides up to 20 mA at OUT2 and 40 mA at OUT1, and operates with <35 µA quiescent current - enabling multi-day operation in hearing instruments and portable smart card readers.
For engineers reviewing the TPS60301DGS datasheet, TPS60301DGS pinout, TPS60301DGS application, or TPS60301DGS equivalent, this page details its LinSkip mode operation, open-drain power-good supervision, VSSOP-10 package constraints, and dual-output load-sharing behavior critical for low-voltage, low-noise embedded power design.
Technical Context
The TPS60301DGS implements a two-stage switched-capacitor architecture: first stage doubles VIN to generate OUT1; second stage quadruples VIN (via 3×/4× auto-selection) to regulate OUT2 at 3 V. It uses LinSkip mode - seamlessly transitioning between pulse-skipping (light load) and constant-frequency linear regulation (≥7.5 mA load) - minimizing output ripple while maintaining efficiency across 0.9–1.8-V input range.
Its power-good (PG) output is open-drain, activated when OUT2 reaches ≥98% of nominal voltage, and pulled low during shutdown. Load isolation on disable reduces battery leakage to ≤0.05 µA, extending shelf life. No inductors are required; only five 1-µF ceramic capacitors enable full implementation.
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 | 3.0 V ±4% - tightly regulated rail for MCU I/O or analog sensors requiring stable 3-V supply |
| Max Output Current (OUT2) | 20 mA - sufficient for MSP430-based metering or low-power pagers with burst-mode operation |
| Quiescent Current | <35 µA - enables >1-year shelf life in always-on medical wearables using coin-cell or AA batteries |
| Switching Frequency | 470–900 kHz - high-frequency operation allows small 1-µF ceramic flying capacitors and minimizes EMI filtering needs |
| Power-Good Output | Open-drain PG - provides system reset or sequencing signal when OUT2 stabilizes; requires external pull-up |
| Shutdown Current | 0.05 µA - isolates load from battery, preventing parasitic drain during storage or sleep modes |
Pinout & Package
TPS60301DGS 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 medical and consumer devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Device-enable input | Active-high logic control; drives device into ultra-low-IQ shutdown (0.05 µA) when low |
| VIN | Supply input | 0.9–1.8-V battery input; requires ≥1-µF ceramic bypass capacitor to GND |
| C1+, C1− | Flying capacitor 1 terminals | Form first charge-pump stage; connect 1-µF ceramic capacitor between C1+ and C1− |
| C2+, C2− | Flying capacitor 2 terminals | Form second charge-pump stage; connect 1-µF ceramic capacitor between C2+ and C2− |
| OUT1 | 2×VIN unregulated output | Delivers up to 40 mA; used for bias rails or auxiliary loads not requiring tight regulation |
| OUT2 | Regulated 3-V output | Main power rail; supplies core logic or analog circuitry with ±4% accuracy over temperature and load |
| PG | Power-good detector output | Open-drain signal active high when OUT2 ≥98% of 3 V; requires external pull-up resistor (100 kΩ–1 MΩ) |
| GND | Ground reference | Common return path for all capacitors and outputs; must be low-impedance plane for ripple suppression |
Key Features
| Feature | Design Value |
|---|---|
| LinSkip operating mode | Automatically switches between pulse-skipping (low IQ) and constant-frequency linear regulation (low noise) based on load current threshold (7.5 mA typical) |
| No-inductor design | Eliminates magnetic components and associated EMI; enables compact, low-profile layouts in hearing aids and smart cards |
| Dual independent outputs | OUT1 (2×VIN) and OUT2 (3 V) can be loaded simultaneously - total OUT1 current ≤40 mA, OUT2 ≤20 mA - supporting mixed-voltage subsystems |
| Load isolation in shutdown | Disconnects battery from both outputs during EN = low, reducing standby leakage to ≤1 µA per output |
| Thermal performance | RθJA = 156.1°C/W - enables reliable operation up to 125°C junction temperature with minimal heatsinking in sealed enclosures |

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 |
|---|---|---|---|
| TPS60300DGS | Identical pinout and electrical specs, but outputs 3.3 V (±4%) at OUT2 instead of 3 V | Suitable where system logic requires 3.3-V I/O compatibility rather than 3-V analog precision | Select TPS60300DGS if downstream MCU or sensor specifies 3.3-V nominal supply with tighter tolerance than LDO can provide |
| MAX680ESA+ | Single-output, 5-V fixed charge pump; no PG output; requires 2.0–6.0-V input; higher IQ (120 µA) | Lacks dual-rail capability and power supervision; suited for legacy 5-V logic rails only | Choose MAX680ESA+ only for retrofitting existing 5-V designs where 3-V regulation and PG are unnecessary |
Compared with TPS60301DGS, TPS60300DGS offers identical form-factor and efficiency but targets 3.3-V systems, while MAX680ESA+ sacrifices regulation accuracy, supervision, and low-voltage operation for simple 5-V generation - making TPS60301DGS uniquely suited for modern sub-2-V battery-powered instrumentation.

FAQ
What is the regulated output voltage of the TPS60301DGS?
The TPS60301DGS provides a regulated 3.0-V ±4% output at OUT2, verified across 0.9–1.8-V input range and 0–20-mA load. This specification is confirmed in Section 8.5 of the SLVS302B datasheet under VOUT(OUT2) test conditions for TPS60301/TPS60303 variants. OUT1 delivers an unregulated 2×VIN output.
Does the TPS60301DGS require external inductors?
No, the TPS60301DGS is a switched-capacitor charge pump and requires no inductors. It operates with only five 1-µF ceramic capacitors: one input (CIN), two flying (C1F, C2F), and two output (COUT1, COUT2). This inductor-free design is explicitly stated in the Features section and Typical Application Schematic of the SLVS302B datasheet.
How does the power-good (PG) output function on the TPS60301DGS?
The TPS60301DGS features an open-drain PG output that goes high when OUT2 reaches ≥98% of 3.0 V and pulls low during shutdown or undervoltage. As specified in Section 8.5, it requires an external pull-up resistor (100 kΩ–1 MΩ) to OUT1 or OUT2. PG is not internally driven high - unlike push-pull variants TPS60302/TPS60303.
What is the maximum continuous output current for OUT2 on the TPS60301DGS?
The TPS60301DGS delivers up to 20 mA continuously at OUT2 when VIN ≥1.0 V and OUT1 is unloaded, as documented in the Device Comparison Table and Electrical Characteristics (Section 8.5). At VIN = 0.9 V, max OUT2 current drops to 12 mA. Total combined output current must respect individual stage limits: OUT1 ≤40 mA, OUT2 ≤20 mA.
What package type is used for the TPS60301DGS?
The TPS60301DGS uses the 10-pin VSSOP (DGS) package, measuring 3.05 mm × 4.98 mm with 0.5-mm lead pitch. This information is confirmed in the Device Information table (page 2) and Mechanical, Packaging, and Orderable Information section (page 20) of the SLVS302B datasheet. The DGS suffix explicitly denotes this VSSOP variant.
