Product details
Overview
TPS60313DGS from Texas Instruments is a dual-output, regulated charge pump DC/DC converter optimized for single-cell alkaline/NiMH/NiCd battery operation (0.9 V–1.8 V input), delivering 2×VIN on OUT1 (up to 40 mA) and regulated 3-V ±4% on OUT2 (up to 20 mA) with push-pull power-good output. It integrates snooze mode (2 µA quiescent current), automatic 3x/4x conversion mode selection, and requires only five 1-µF ceramic capacitors - used in hearing instruments and portable smart card readers.
For engineers reviewing the TPS60313DGS datasheet, TPS60313DGS pinout, TPS60313DGS application, or TPS60313DGS equivalent, key selection criteria include its 3-V regulated output with push-pull PG, snooze-mode efficiency at microamp loads, dual-output current capability under shared power budget constraints, and MSOP-10 package compatibility with space-constrained battery-powered designs.
Technical Context
The TPS60313DGS employs two cascaded charge pump stages: CP1 operates as a voltage doubler (2×VIN) for OUT1, while CP2 functions as a regulated 1.5×/2× stage with internal reference and error amplifier to maintain 3-V output on OUT2. Its oscillator dynamically selects between 3x and 4x conversion modes based on input voltage to sustain regulation across 0.9 V–1.8 V.
Snooze mode disables the high-accuracy error amplifier (4% tolerance, 50 µA supply) and engages a low-power regulator (10% tolerance, 2 µA supply) when load current falls below 1–4 mA on OUT2, reducing quiescent current to ≤4 µA at ≤25°C. The push-pull PG output actively drives high (≥2.7 V @ –5 mA) and low (≤0.3 V @ 1.6 mA) without external pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.9 V to 1.8 V - supports single-cell alkaline, NiCd, or NiMH batteries without undervoltage lockout. |
| OUT2 Output Voltage | 3.0 V ±4% - tightly regulated output for analog sensors or low-voltage MCUs like MSP430. |
| OUT2 Max Output Current | 20 mA - sufficient for display bias, RF front-end bias, or sensor excitation in portable instruments. |
| OUT1 Output Voltage | 2 × VIN - unregulated but stable doubling for auxiliary rails (e.g., LCD bias, op-amp supplies). |
| Quiescent Current (Snooze) | ≤4 µA at ≤25°C - enables multi-year battery life in intermittently active devices like smart card readers. |
| Switching Frequency | 470 kHz to 900 kHz - balances EMI suppression and capacitor size; no inductor required. |
| Power-Good Output | Push-pull - eliminates need for external pull-up resistor; supports direct interface to MCU reset or enable pins. |
Pinout & Package
TPS60313DGS is housed in a microsmall 10-pin MSOP package (3.05 mm × 4.98 mm), optimized for high-density PCB layouts in portable medical and metering applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SNOOZE (Pin 1) | Input control | Active-low enable for snooze mode; must be pulled low to activate ultra-low-quiescent operation. |
| C1– (Pin 2) | Flying capacitor terminal | Negative node of first flying capacitor (C1F); connects to ground during charge phase of CP1 doubler. |
| VIN (Pin 3) | Input supply | Main battery input; bypassed with ≥1-µF ceramic capacitor to stabilize input impedance and reduce ripple. |
| C1+ (Pin 4) | Flying capacitor terminal | Positive node of C1F; switched between VIN and OUT1 to implement voltage doubling. |
| OUT1 (Pin 5) | Output | 2×VIN unregulated output; delivers up to 40 mA; requires 1-µF ceramic output capacitor to GND. |
| OUT2 (Pin 6) | Output | Regulated 3.0 V ±4% output; delivers up to 20 mA; requires 1-µF ceramic output capacitor to GND. |
| C2+ (Pin 7) | Flying capacitor terminal | Positive node of second flying capacitor (C2F); switched to generate regulated 3-V output on OUT2. |
| C2– (Pin 8) | Flying capacitor terminal | Negative node of C2F; referenced to GND or OUT1 depending on conversion phase. |
| GND (Pin 9) | Ground reference | Primary return path for all internal circuits and external capacitors; must be low-impedance plane. |
| PG (Pin 10) | Power-good indicator | Push-pull output asserting high when OUT2 reaches ≥98% of 3.0 V; sinks 1.6 mA, sources –5 mA. |
Key Features
| Feature | Design Value |
|---|---|
| No-inductor architecture | Eliminates magnetic EMI and board area penalty; uses only five 1-µF ceramic capacitors for full BOM. |
| Auto-selecting conversion ratio | Switches between 3× and 4× modes internally to maintain regulation across full 0.9 V–1.8 V input range. |
| Push-pull power-good output | Directly interfaces with MCU GPIO or reset logic without pull-up resistors; reduces component count by one. |
| Snooze mode threshold | Activates automatically below 1–4 mA OUT2 load; extends battery life in standby without firmware intervention. |
| Low-noise output ripple | 30 mVP–P at 20 mA OUT2 load; compatible with noise-sensitive analog front-ends in hearing instruments. |

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 pinout and package; open-drain PG output requiring external 100-kΩ to 1-MΩ pull-up resistor. | Requires additional resistor; less suitable for direct MCU GPIO interface without level translation. | Select when legacy design uses open-drain PG or when sourcing current from PG is unnecessary. |
| TPS60313DR | Identical electrical specs and pinout; DGS vs DR denotes tape-and-reel packaging (2500 pcs/reel vs 250 pcs/reel). | No functional difference; DR variant intended for automated SMT assembly with larger reel quantities. | Select DR for high-volume production; DGS for prototyping or low-volume builds. |
Compared with TPS60311DGS, TPS60313DGS eliminates external pull-up dependency via push-pull PG, reducing BOM count and improving startup reliability; compared with TPS60313DR, the DGS variant offers smaller reel quantity for evaluation and small-batch use without sacrificing performance.

FAQ
What is the regulated output voltage of the TPS60313DGS?
The TPS60313DGS provides a regulated 3.0 V ±4% output on OUT2, verified across 0.9 V–1.8 V input and 0–20 mA load. This tight regulation supports analog sensors and low-voltage MCUs. OUT1 delivers an unregulated 2×VIN output, scalable from 1.8 V to 3.6 V depending on battery state. Both outputs are specified per SLVS362A datasheet revision August 2001.
How does snooze mode operate on the TPS60313DGS?
Snooze mode on the TPS60313DGS activates when the SNOOZE pin is pulled low and OUT2 load drops below 1–4 mA. It disables the main error amplifier and engages a low-power regulator, reducing quiescent current to ≤4 µA at ≤25°C. The output remains regulated to 3.0 V ±10%, and the device automatically exits snooze when load exceeds threshold. This behavior is confirmed in the "Snooze Mode" section of the TPS60313DGS datasheet.
What is the function of the PG pin on the TPS60313DGS?
The PG pin on the TPS60313DGS is a push-pull power-good output that asserts high (≥2.7 V @ –5 mA) when OUT2 reaches ≥98% of 3.0 V. It actively drives low (≤0.3 V @ 1.6 mA) during undervoltage or shutdown. Unlike open-drain variants, it requires no external pull-up resistor - enabling direct connection to MCU reset or enable inputs. This functionality is documented in the "Terminal Functions" and "Electrical Characteristics" sections of the TPS60313DGS datasheet.
Which external capacitors are required for the TPS60313DGS?
The TPS60313DGS requires exactly five 1-µF ceramic capacitors: CIN (input), C1F and C2F (flying), and C(OUT1)/C(OUT2) (output filters). All are specified as X7R/X5R dielectric types in 0805 or 1206 case sizes. Lower values degrade output power and stability; larger values reduce ripple but increase cost and board area. This requirement is explicitly stated in the "Description" and "Capacitor Selection" sections of the TPS60313DGS datasheet.
What is the maximum output current capability of the TPS60313DGS?
The TPS60313DGS delivers up to 40 mA on OUT1 (2×VIN) when OUT2 is unloaded, and up to 20 mA on OUT2 (3.0 V) when OUT1 is unloaded. Under simultaneous loading, total current drawn from the first charge pump stage must not exceed 40 mA - e.g., 20 mA on OUT1 and 10 mA on OUT2 is valid. These limits are defined in the "Description (continued)" and "Recommended Operating Conditions" tables of the TPS60313DGS datasheet.
