Product details
Overview
TPS60313DGSR from Texas Instruments is a dual-output, regulated charge pump DC/DC converter optimized for single-cell battery systems. It delivers 2×VIN at OUT1 (up to 40 mA) and a regulated 3-V ±4% output at OUT2 (up to 20 mA) from 0.9–1.8-V input, with push-pull power-good (PG) output and snooze mode enabling <2 µA quiescent current. It targets ultra-low-power portable instrumentation and hearing aids.
For engineers reviewing the TPS60313DGSR datasheet, TPS60313DGSR pinout, TPS60313DGSR application, or TPS60313DGSR equivalent, key selection criteria include its 3-V regulated output tolerance, push-pull PG interface, snooze-mode current threshold (1–4 mA), 470–900 kHz switching frequency, and MSOP-10 package compatibility with space-constrained medical and metering designs.
Technical Context
The TPS60313DGSR integrates two independent charge pump stages: a voltage doubler (CP1) for OUT1 and a regulated 1.5×/2× stage (CP2) with internal reference and error amplifier for precise 3-V regulation at OUT2. Its automatic mode selection between 3× and 4× conversion maintains high efficiency across the 0.9–1.8-V input range.
Snooze mode disables the main error amplifier and engages a low-quiescent 10%-tolerance regulator when load current drops below 1–4 mA, reducing supply current to ≤4 µA at ≤25°C. The push-pull PG output actively drives high (≥2.7 V @ –5 mA) or low (≤0.3 V @ 1.6 mA) without external pull-up, supporting reliable power sequencing in MSP430-based systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output 1 (OUT1) | 2×VIN unregulated output; delivers up to 40 mA at 1-V input with no load on OUT2 - enables rail-to-rail analog circuitry from low-voltage batteries. |
| Output 2 (OUT2) | Regulated 3-V ±4% output; supplies up to 20 mA while maintaining tight voltage stability over temperature and line/load variations - suitable for precision ADCs and microcontrollers. |
| Input Voltage Range | 0.9 V to 1.8 V - supports single alkaline, NiCd, or NiMH cells across full discharge curve without brownout. |
| Snooze Mode IQ | ≤4 µA at ≤25°C - extends battery life in standby by reducing consumption below typical self-discharge rates of primary cells. |
| Switching Frequency | 470–900 kHz - enables use of small 1-µF ceramic capacitors and minimizes EMI in noise-sensitive audio and sensor applications. |
| Power-Good Output | Push-pull type; active-high at ≥98% of nominal OUT2 voltage - eliminates need for external pull-up resistor and simplifies power-up sequencing logic. |
| Package | 10-pin MSOP (DGS); 3.05 mm × 4.98 mm footprint - fits compact wearable and hearing instrument PCB layouts with minimal board area. |
Pinout & Package
TPS60313DGSR uses the DGS (10-pin MSOP) package with exposed pad for thermal performance. Pin functions are validated per TI SLVS362A datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SNOOZE | Input control | Active-low enable for snooze mode; pulling low reduces IQ to ≤4 µA and relaxes regulation to ±10% - critical for ultra-low-power sleep states. |
| C1−, C1+ | Flying capacitor terminals | Interface with 1-µF ceramic flying capacitor C1F to implement first-stage voltage doubling for OUT1 - requires low-ESR placement adjacent to IC. |
| VIN | Input supply | Accepts 0.9–1.8-V battery input; bypassed with ≥1-µF ceramic capacitor to stabilize input impedance and reduce ripple injection. |
| OUT1 | Unregulated output | Delivers 2×VIN (e.g., ~2.6 V from 1.3-V cell); used for analog rails or non-critical peripherals where regulation margin is acceptable. |
| PG | Power-good indicator | Push-pull output asserts high when OUT2 reaches ≥98% of 3 V; sinks 1.6 mA or sources –5 mA - drives logic directly without pull-up. |
| GND | Ground reference | Common return for all internal circuits and external capacitors; must be low-impedance plane to minimize noise coupling into sensitive OUT2 regulation loop. |
| C2−, C2+ | Flying capacitor terminals | Connect to 1-µF ceramic C2F to support second-stage regulated charge pump for OUT2 - timing and ESR directly impact regulation accuracy and transient response. |
| OUT2 | Regulated output | Stable 3-V ±4% supply for microcontrollers (e.g., MSP430), sensors, or RF front-ends; load step response tested to 2–18 mA with <20 mV overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic components and associated EMI; enables fully ceramic, low-profile BOM using only five 1-µF X7R/X5R capacitors. |
| Automatic mode selection | Internally switches between 3× and 4× charge pump ratios based on input voltage and load - sustains >85% efficiency from 0.9 V to 1.8 V across 1–20 mA loads. |
| Integrated power supervisor | Push-pull PG output provides deterministic power-up/down signaling for MSP430 reset control and system-level sequencing without external comparators. |
| Low-noise regulation | 30-mVP–P output ripple at 20 mA on OUT2 (1.2-V input) - meets requirements for low-noise amplifiers and 12-bit+ ADC references. |
| Thermal robustness | RθJA = 200°C/W on typical EVM; dissipates ≤46 mW at max load - junction rise limited to 10°C above ambient, enabling operation up to 115°C ambient. |
Applications

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 |
|---|---|---|---|
| TPS60312DGSR | Identical pinout and electrical specs except 3.3-V ±4% regulated OUT2 instead of 3-V; same push-pull PG. | Used where system logic requires 3.3-V I/O compatibility (e.g., interfacing with 3.3-V UART or SPI peripherals). | Select TPS60312DGSR when 3.3-V regulation is mandatory; otherwise TPS60313DGSR offers tighter voltage alignment with 3-V microcontrollers like MSP430FRxx. |
| MAX17222ETA+ | Single-output 3-V boost converter (not dual); 95% peak efficiency; 1.8–5.5-V input; different 6-pin TSOT package. | Lacks OUT1 doubler and PG output; requires external supervision circuitry for power sequencing. | Choose MAX17222ETA+ only if single-rail 3-V supply suffices and board space allows TSOT-6; not drop-in compatible due to pin count, function, and package mismatch. |
Compared with TPS60312DGSR and MAX17222ETA+, the TPS60313DGSR uniquely combines dual-rail generation (2×VIN + regulated 3 V), push-pull PG, and snooze-mode IQ ≤4 µA in a space-optimized MSOP-10 - making it the sole option for battery-powered systems requiring both analog headroom and precise 3-V digital logic from sub-1.8-V sources.

FAQ
What is the regulated output voltage of the TPS60313DGSR?
The TPS60313DGSR provides a regulated 3-V ±4% output at OUT2 across –40°C to 85°C and 0.9–1.8-V input range. This specification is confirmed in the Electrical Characteristics table of SLVS362A, where VO(OUT2) = 2.88 V (min) to 3.12 V (max) at 1–20 mA load and 1–1.8-V VIN. The 3-V output aligns with MSP430 and other 3-V logic families, distinguishing it from the 3.3-V variants TPS60310/TPS60312.
Does the TPS60313DGSR support snooze mode, and what is its quiescent current?
Yes, the TPS60313DGSR supports snooze mode enabled by pulling the SNOOZE pin low. In snooze mode, its quiescent supply current is ≤4 µA at ≤25°C and ≤10 µA at 60°C, verified in the Electrical Characteristics table under "I(SQ) Quiescent supply current in snooze mode." This ultra-low current extends battery life in intermittent-use applications such as home sensors and hearing aids.
What type of power-good output does the TPS60313DGSR feature?
The TPS60313DGSR features a push-pull power-good (PG) output, as specified in the "AVAILABLE OPTIONS" table and confirmed in the Electrical Characteristics section for TPS60313. It actively drives high (≥2.7 V @ –5 mA) or low (≤0.3 V @ 1.6 mA), eliminating the need for an external pull-up resistor - unlike the open-drain PG of TPS60311/TPS60310.
What are the absolute maximum ratings for input voltage and output current on the TPS60313DGSR?
The TPS60313DGSR has an absolute maximum input voltage of –0.3 V to 2 V and maximum continuous output currents of 80 mA at OUT1 and 40 mA at OUT2, per the Absolute Maximum Ratings table in SLVS362A. These limits define safe operating boundaries; recommended conditions specify 0.9–1.8-V input and ≤40 mA (OUT1) / ≤20 mA (OUT2) for reliable regulation and thermal performance.
Can the TPS60313DGSR operate from a single NiMH cell?
Yes, the TPS60313DGSR is explicitly designed for single-cell operation including NiMH batteries, which deliver 0.9–1.8-V across their discharge curve. The datasheet states "from a 0.9-V to 1.8-V input voltage (one alkaline, NiCd, or NiMH battery)" in the Description section, and efficiency curves (Figures 1–2) confirm stable operation down to 0.9 V with >80% efficiency at 10 mA load.
