Product details
Overview
TPS60310DGS from Texas Instruments is a dual-output, regulated charge pump DC/DC converter optimized for single-cell battery operation (0.9 V–1.8 V input), delivering 2×VIN on OUT1 (up to 40 mA) and regulated 3.3 V ±4% on OUT2 (up to 20 mA), with snooze mode quiescent current < 2 µA. It enables compact, low-EMI power in hearing instruments and portable smart card readers.
For engineers reviewing the TPS60310DGS datasheet, TPS60310DGS pinout, TPS60310DGS application, or TPS60310DGS equivalent, key selection criteria include its open-drain power-good output, MSOP-10 package footprint, 3.3-V regulated output tolerance, snooze-mode efficiency at microamp loads, and compatibility with five 1-µF ceramic capacitors only.
Technical Context
The TPS60310DGS integrates two independent charge pump stages: a voltage doubler (CP1) generating OUT1 at 2×VIN, and a regulated 1.5×/2× charge pump (CP2) with internal reference and error amplifier to maintain 3.3 V on OUT2. It auto-selects between 3× and 4× conversion modes to sustain regulation across the 0.9–1.8 V input range.
Snooze mode disables the high-accuracy error amplifier and engages a low-quiescent 10%-tolerance regulator, reducing supply current to ≤4 µA at ≤25°C while maintaining output within 3.3 V ±10%. The SNOOZE pin (active-low) controls entry/exit, and PG asserts high when OUT2 reaches ≥98% of nominal voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.9 V to 1.8 V - supports single alkaline/NiCd/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. |
| OUT2 Max Output Current | 20 mA - sufficient to power MSP430 peripherals, LCD bias, or low-power sensors simultaneously. |
| OUT1 Output Voltage | 2×VIN - provides scalable unregulated rail up to ~3.6 V for display drivers or LED biasing. |
| Quiescent Current (Snooze) | ≤4 µA at ≤25°C - extends battery life in standby by consuming less than typical battery self-discharge. |
| Switching Frequency | 470–900 kHz - enables use of small 1-µF ceramic flying capacitors and minimizes EMI filtering burden. |
| Power-Good Output | Open-drain - requires external pull-up; signals valid 3.3-V rail for sequencing or wake-up logic. |
Pinout & Package
TPS60310DGS is housed in a microsmall 10-pin MSOP package (3.05 mm × 4.98 mm), lead-free and RoHS-compliant, designed for high-density portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SNOOZE | Active-low enable input | Pulling low enters ultra-low-power snooze mode; must not exceed highest applied voltage (e.g., OUT1). |
| C1−, C1+ | Flying capacitor terminals (CP1 stage) | Connect 1-µF ceramic capacitor between C1+ and C1− to implement 2×VIN doubler for OUT1. |
| VIN | Main power input | Bypass with ≥1-µF ceramic capacitor to GND; accepts 0.9–1.8 V from single-cell battery. |
| OUT1 | Unregulated 2×VIN output | Delivers up to 40 mA; bypass with 1-µF ceramic capacitor to GND for stability and ripple reduction. |
| PG | Open-drain power-good indicator | Asserts high when OUT2 ≥98% of 3.3 V; requires external pull-up (100 kΩ–1 MΩ) to OUT1 or OUT2. |
| GND | Ground reference | Common return for all capacitors and load paths; must be low-impedance plane for noise control. |
| C2−, C2+ | Flying capacitor terminals (CP2 stage) | Connect 1-µF ceramic capacitor between C2+ and C2− to support regulated 3.3-V generation on OUT2. |
| OUT2 | Regulated 3.3-V output | Delivers up to 20 mA with ±4% accuracy; bypass with 1-µF ceramic capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI and board area overhead; uses only five 1-µF ceramic capacitors for full solution. |
| Snooze mode with 2 µA IQ | Reduces system standby power below battery self-discharge rate-critical for multi-year medical device battery life. |
| Auto-ranging 3×/4× charge pump | Maintains regulation across full 0.9–1.8 V input range without manual configuration or external components. |
| Integrated power-good supervisor | Provides reliable power-up/down sequencing signal for MSP430 or other low-power MCUs without extra IC. |
| MSOP-10 thermal performance | RθJA = 294°C/W (unsoldered); dissipates ≤46 mW at max load, limiting junction rise to ~10°C on typical EVM. |
Applications
| Hearing Instruments | Portable Smart Card Readers |
|---|---|
Use Scenario: Miniature in-the-ear (ITE) hearing aids powered by zinc-air button cells (1.4 V nominal, discharging to 0.9 V). IC Role / Device Role / Timing Role: Primary 3.3-V supply for ultra-low-power DSP and microphone preamp; OUT1 powers electret bias.

IC Role / Device Role / Timing Role: Generates clean 3.3-V rail for secure element and contactless transceiver; PG signals ready state to host MCU. Use Value: Open-drain PG simplifies level-shifting to 1.8-V host logic; no inductor avoids interference with NFC antenna. |
| Metering with MSP430 | Home Automation Sensors |
Use Scenario: Battery-powered water/gas meter using MSP430FR5969 with LCD and ultrasonic sensing. IC Role / Device Role / Timing Role: Supplies regulated 3.3-V for MCU core and ADC reference; OUT1 powers LCD segment drivers. Use Value: 3.3-V ±4% output ensures ADC accuracy over full battery life; 20-mA OUT2 supports simultaneous LCD + sensor burst. |

IC Role / Device Role / Timing Role: Provides stable 3.3-V rail for RF SoC and digital sensor interface; snooze mode enables 10-year shelf life. Use Value: 2 µA snooze current matches AA self-discharge; 1-µF capacitor count minimizes BOM cost and size. |
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 |
|---|---|---|---|
| TPS60311DGS | Same package and pinout; delivers regulated 3-V (±4%) on OUT2 instead of 3.3 V. | Required where legacy 3-V logic or sensor interfaces dominate; incompatible with 3.3-V-only peripherals. | Select when system-level voltage rails mandate strict 3.0-V compliance, not 3.3-V. |
| TPS60312DGS | Identical electrical specs except push-pull (not open-drain) PG output; same 3.3-V OUT2. | Eliminates need for external pull-up resistor; reduces component count but increases PG sink current demand. | Choose when simplifying BOM and driving heavier PG loads (e.g., direct GPIO wake-up without pull-up). |
Compared with TPS60311DGS and TPS60312DGS, the TPS60310DGS uniquely combines 3.3-V regulation with open-drain PG-enabling flexible level-shifting and minimal leakage in always-on monitoring nodes where pull-up resistor placement affects layout density.

FAQ
What is the maximum output current capability of TPS60310DGS on OUT2?
The TPS60310DGS delivers up to 20 mA on OUT2 when OUT1 is unloaded and VIN ≥ 1.1 V. At lower input voltages (e.g., VIN = 0.9 V), the guaranteed maximum drops to 10 mA. Both outputs may be loaded simultaneously, but total current drawn from the first charge pump stage (supplying OUT1) must not exceed 40 mA.
Does TPS60310DGS require an inductor in its application circuit?
No, the TPS60310DGS is a capacitor-based charge pump and requires no inductor. Its complete solution uses only five 1-µF ceramic capacitors: one input (CIN), two flying (C1F, C2F), and two output (C(OUT1), C(OUT2))-reducing EMI, board area, and BOM cost versus inductive DC/DC converters.
How does the snooze mode function in TPS60310DGS, and what triggers exit?
In snooze mode (enabled by pulling SNOOZE low), the TPS60310DGS reduces quiescent current to ≤4 µA while maintaining OUT2 within 3.3 V ±10%. It exits automatically when load current exceeds ~2 mA on OUT2 or ~8 mA on OUT1, re-engaging full regulation and higher efficiency switching.
What is the role of the PG pin on TPS60310DGS, and how must it be interfaced?
The PG pin on TPS60310DGS is an open-drain output that goes high when OUT2 reaches ≥98% of 3.3 V. It requires an external pull-up resistor (100 kΩ–1 MΩ) to either OUT1 or OUT2. If unused, PG must remain unconnected-no internal pull-up exists.
Can TPS60310DGS operate with input voltage below 0.9 V?
No-the absolute minimum input voltage for functional operation is 0.9 V per datasheet specifications. Below this threshold, regulation cannot be maintained, startup fails, and device behavior is undefined. The recommended operating range remains strictly 0.9 V to 1.8 V.
