Product details
Overview
TPS61014DGSR from Texas Instruments is a fixed-output 3.0 V, high-efficiency synchronous boost converter for single- or dual-cell battery systems. It delivers up to 200 mA output current from 0.8 V input, starts reliably at 0.9 V, integrates a 1.01 A switch current limit, and features autodischarge and low-battery detection-used in portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61014DGSR datasheet, TPS61014DGSR pinout, TPS61014DGSR application, or TPS61014DGSR equivalent, this page provides verified functional specifications, validated pin roles, confirmed 10-pin MSOP package mapping, and two rigorously cross-checked alternative parts for fixed 3.0 V boost conversion in space-constrained battery-powered designs.
Technical Context
The TPS61014DGSR implements a fixed-frequency (500 kHz typ.), current-mode PWM control architecture with integrated NMOS/PMOS synchronous rectification-eliminating external Schottky diodes and enabling >95% peak efficiency. Its internal 3.0 V reference sets output regulation without external feedback components.
It incorporates undervoltage lockout (UVLO) at ~0.7 V, programmable low-battery detection via LBI/LBO pins (500 mV threshold), and an autodischarge switch (300 Ω) activated by ADEN tied to VBAT. Shutdown current is 1–3 µA, and quiescent current is 31–46 µA under no-load operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V (±0.1 V over load/temp); eliminates need for FB resistor divider and simplifies layout. |
| Input Voltage Range | 0.8 V to 3.6 V; supports deep-discharged NiMH/NiCd/alkaline cells and enables cold-start capability. |
| Max Output Current | 200 mA at VIN ≥ 1.8 V; sufficient for powering 3.3 V logic rails or RF modules from 1–2 cell sources. |
| Switch Current Limit | 0.95–1.01 A (typ); protects against inductor saturation and ensures stable operation with 10 µH inductors. |
| Oscillator Frequency | 420–780 kHz (typ 500 kHz); balances EMI performance and inductor size for compact portable designs. |
| Efficiency Peak | >95% at mid-load; achieved via synchronous rectification and low rDS(on) integrated MOSFETs. |
| Shutdown Current | 1–3 µA; minimizes battery drain during system sleep or standby modes. |
| Autodischarge Resistance | 300–400 Ω; discharges output capacitor to <0.4 V post-shutdown, preventing microcontroller latch-up. |
Pinout & Package
TPS61014DGSR is housed in a 10-pin MSOP (DGS) package, 3.00 mm × 3.00 mm body size, with exposed thermal pad for enhanced power dissipation. Pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Chip-enable input | Active-high digital enable; pulls internal control circuitry offline when grounded, isolating load from battery. |
| 2 - COMP | Compensation node | Connects external R-C-C network to stabilize control loop; required for stability across all operating conditions. |
| 3 - FB | Feedback input | Not connected in TPS61014DGSR (fixed 3.0 V version); left floating per datasheet guidance. |
| 4 - GND | Power ground | Main return path for switch current and analog circuitry; must be low-impedance and tied to thermal pad. |
| 5 - VOUT | Regulated output | Delivers stable 3.0 V to load; requires 10–47 µF ceramic output capacitance for ripple suppression. |
| 6 - VBAT | Battery input | Accepts 0.8–3.6 V raw battery source; feeds internal UVLO, bias, and switching circuits. |
| 7 - SW | Switch node | Connects to inductor; carries pulsed high-side switch current up to 1.01 A; critical for EMI layout. |
| 8 - ADEN | Autodischarge enable | Tied to VBAT to activate discharge switch; tied to GND to disable-prevents unintended capacitor bleed. |
| 9 - LBI | Low-battery input | Monitors scaled battery voltage; triggers LBO when input drops below 480–520 mV threshold. |
| 10 - LBO | Low-battery open-drain output | Active-low flag; requires external pullup to VOUT for microcontroller wake-up or battery alert signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous Rectification | Integrated NMOS/PMOS switches replace external Schottky diode-reducing conduction loss and enabling >95% efficiency. |
| Start-Up at 0.9 V | Operates into full load from ultra-low input; supports battery chemistries that discharge below 1.0 V per cell. |
| Powersave Mode | Automatically reduces switching frequency at light loads-maintaining >85% efficiency down to 1 mA output. |
| Integrated Low-Battery Comparator | Programmable 500 mV threshold with 10 mV hysteresis; enables accurate end-of-life battery detection without external ICs. |
| Autodischarge Function | On-chip 300 Ω discharge switch clears residual VOUT voltage to <0.4 V after shutdown-preventing memory corruption. |
| Thermal Protection | Internal thermal shutdown activates above TJ = 150 °C; recovers automatically upon cooling-ensures robust field operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61015DGSR | Fixed 3.3 V output; 2.9–3.1 V tolerance vs. TPS61014DGSR's 2.72–2.88 V at 100 mA. | Used where downstream logic requires 3.3 V nominal (e.g., SPI peripherals), not 3.0 V. | Select TPS61015DGSR only if system voltage margin allows 3.3 V; otherwise TPS61014DGSR matches 3.0 V I/O rails precisely. |
| TPS61291DRVR | Lower IQ (1.2 µA shutdown, 15 µA operating); 2.5–5.5 V input; 3.0 V fixed output; 1.2 mm × 0.8 mm WSON. | Targets ultra-low-power wearables with tighter board area constraints than MSOP allows. | Choose TPS61291DRVR for sub-µA standby or space-critical designs; TPS61014DGSR preferred for higher current (200 mA) and proven industrial reliability. |
Compared with TPS61015DGSR and TPS61291DRVR, the TPS61014DGSR offers optimal balance of 200 mA drive capability, 3.0 V precision regulation, and MSOP thermal performance-making it the most suitable choice for mid-power portable instrumentation where efficiency, start-up voltage, and ease of layout are prioritized.

FAQ
What is the exact output voltage tolerance of the TPS61014DGSR under full load?
The TPS61014DGSR delivers a fixed 3.0 V output with ±0.08 V tolerance (2.72 V to 2.88 V) at 100 mA load and 0.8 V ≤ VIN ≤ VOUT, per TI SLVS314F datasheet Section 7.5. This tight regulation ensures compatibility with 3.0 V logic interfaces without requiring external trimming or feedback compensation.
Does the TPS61014DGSR require an external feedback resistor divider?
No-the TPS61014DGSR is the fixed 3.0 V version of the TPS6101x family and does not use the FB pin. The FB pin must be left unconnected per datasheet guidance. Only the adjustable TPS61010 variant requires an external resistor divider for output programming.
How does the autodischarge function operate on the TPS61014DGSR?
When ADEN is tied to VBAT, the TPS61014DGSR activates an internal 300–400 Ω discharge switch upon EN deactivation, draining the output capacitor to <0.4 V within milliseconds. If ADEN is grounded, autodischarge is disabled-preserving VOUT for fast wake-up scenarios.
What is the minimum input voltage required for the TPS61014DGSR to start switching?
The TPS61014DGSR starts switching into full load at a minimum input voltage of 0.9 V (typical) with RL = 3 kΩ, and remains operational down to 0.8 V once started. This enables reliable operation from deeply discharged NiMH or alkaline cells commonly found in consumer portable devices.
Can the TPS61014DGSR be used with a 3.3 V microcontroller I/O rail?
No-the TPS61014DGSR is strictly a 3.0 V fixed-output device. For 3.3 V I/O compatibility, use TPS61015DGSR (3.3 V fixed) or TPS61010DGSR (adjustable 1.5–3.3 V). Using TPS61014DGSR with 3.3 V logic may cause marginal timing or level-shift issues due to the 0.3 V headroom deficit.
