Product details
Overview
TPS61013DGSR from Texas Instruments is a fixed-output 2.5 V, high-efficiency synchronous boost converter for single- or dual-cell battery systems. It delivers up to 200 mA output current from 0.9 V input, starts up at 0.8 V, integrates a 1.3 A switch, and features autodischarge and low-battery detection - used in portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61013DGSR datasheet, TPS61013DGSR pinout, TPS61013DGSR application, or TPS61013DGSR equivalent, this page provides verified functional context, validated pin roles, confirmed 2.5 V fixed-output behavior, real-world efficiency data (≥95%), and direct alternative comparisons for battery-powered system design.
Technical Context
The TPS61013DGSR implements a fixed-frequency (420–780 kHz), current-mode PWM controller with integrated NMOS/PMOS synchronous rectifier - eliminating external Schottky diodes and enabling >95% peak efficiency. Its pulse-by-pulse current limit caps switch current at 0.85–0.93 A depending on output voltage.
It operates in powersave mode below ~10 mA load to minimize switching losses, uses internal 500 mV bandgap reference for LBI/LBO low-battery detection, and isolates load from battery during shutdown via backgate diode disconnect circuitry - ensuring zero residual current path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±3% (2.42–2.58 V) across 0–200 mA load and 1.6–3.3 V input |
| Input Voltage Range | 0.8 V to 3.3 V - supports NiCd/NiMH/alkaline single- or dual-cell operation |
| Max Output Current | 200 mA at VIN ≥ 1.8 V; 100 mA at VIN = 0.8 V - enables sustained runtime in deep-discharge states |
| Switch Current Limit | 0.85–0.93 A - limits peak inductor current to prevent saturation and thermal overload |
| Quiescent Current | 5–8 µA in shutdown (EN = GND); 31–46 µA operating - extends battery life in standby |
| Oscillator Frequency | 420–780 kHz - balances EMI control and inductor size (10–33 µH typical) |
| Efficiency | ≥95% peak - achieved via integrated synchronous rectifier (rDS(on) ≤ 0.51 Ω NMOS / ≤ 0.54 Ω PMOS) |
Pinout & Package
TPS61013DGSR 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 (RθJA = 161.8°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Chip-enable input | Active-high enable: tie to VBAT to operate; GND disables converter and isolates load from battery |
| 2 - COMP | Compensation node | Connect R-C-C network to stabilize control loop; sets frequency response and transient performance |
| 3 - FB | Feedback input | Not connected - TPS61013DGSR has internal 2.5 V divider; FB pin unused in fixed-output variants |
| 4 - GND | Power and signal ground | Common reference for all analog/digital blocks; must be low-impedance connection to thermal pad |
| 5 - VOUT | Regulated output | Delivers stable 2.5 V to load; requires 10–47 µF ceramic output capacitor for stability |
| 6 - VBAT | Input supply | Accepts 0.8–3.3 V battery source; UVLO prevents startup below ~0.7 V |
| 7 - SW | Switch node | Connects to inductor; carries pulsed current up to 0.93 A; requires low-ESR layout |
| 8 - ADEN | Autodischarge enable | Tie to VBAT to discharge output cap during shutdown; GND disables autodischarge |
| 9 - LBI | Low-battery input | Monitor battery via resistive divider; triggers LBO when scaled voltage drops below 500 mV |
| 10 - LBO | Low-battery open-drain output | Pulled low when LBI < 500 mV; requires external pull-up to VOUT for logic-level signaling |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated NMOS/PMOS switches eliminate external Schottky diode, enabling >95% efficiency and reducing BOM count |
| Autodischarge function | 300 Ω internal switch discharges output capacitor to <0.4 V during shutdown - prevents microcontroller latch-up |
| Load isolation in shutdown | Backgate diode disconnect circuitry ensures zero current path from battery to VOUT when EN = GND |
| Powersave mode | Reduces switching frequency at light loads (<10 mA), maintaining >85% efficiency down to 100 µA output |
| Low-battery comparator | 500 mV ±15 mV threshold with 10 mV hysteresis - enables programmable battery monitoring without external components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61012DGSR | Fixed 2.5 V output same as TPS61013DGSR, but tighter initial tolerance (±2.8% vs ±3%) and lower max switch current (0.54–0.56 A) | Lower peak current capability limits use with high-ESR or large-value inductors (>22 µH) | Select TPS61012DGSR only if design requires marginally better output accuracy and lower inrush risk |
| TPS61022RTER | Higher 2.0 A switch current, 2.5 V fixed output, but requires external compensation and lacks LBO/LBI pins | No integrated battery monitoring - necessitates external comparator for low-battery alerts | Choose TPS61022RTER when higher output current (>200 mA) or wider input range (0.3–5.5 V) is required |
Compared with TPS61013DGSR, TPS61012DGSR offers slightly better output accuracy but reduced current headroom, while TPS61022RTER trades integrated battery monitoring for higher drive capability and broader input flexibility - making each suitable for distinct system-level trade-offs.

FAQ
What is the exact output voltage of the TPS61013DGSR and how tightly is it regulated?
The TPS61013DGSR provides a fixed 2.5 V output with guaranteed regulation of ±3% (2.42 V to 2.58 V) across full temperature range (–40°C to 85°C), load (0–200 mA), and input voltage (1.6–3.3 V). This specification is confirmed in Section 7.5 of the SLVS314F datasheet and applies specifically to the DGS-packaged TPS61013DGSR variant - not the adjustable TPS61010 or other family members.
Does the TPS61013DGSR require an external feedback resistor divider?
No - the TPS61013DGSR uses an internal resistor divider to set its fixed 2.5 V output. The FB pin (Pin 3) must remain unconnected per TI's Pin Functions table. Connecting external resistors to FB will disrupt regulation and is not supported. This differs from the TPS61010, which requires external feedback for adjustable output.
How does the autodischarge function work on the TPS61013DGSR and what is its design impact?
When ADEN (Pin 8) is tied to VBAT, the TPS61013DGSR activates an internal 300 Ω discharge switch upon shutdown (EN = GND), reducing VOUT to <0.4 V within milliseconds. This prevents unintended MCU wake-up or memory corruption - critical in portable medical devices where clean power-down is mandatory for regulatory compliance.
What is the minimum input voltage at which the TPS61013DGSR can start up and sustain operation?
The TPS61013DGSR starts up with a minimum input voltage of 0.8 V (typical 0.9 V) into full load, and continues operating down to 0.8 V - verified in Section 7.5 Electrical Characteristics. This enables reliable operation across the full discharge curve of alkaline, NiCd, or NiMH cells, unlike many boost converters that drop out above 1.0 V.
Can the TPS61013DGSR be used without the LBI/LBO low-battery monitoring pins?
Yes - the LBI and LBO pins are optional. If unused, LBI must be tied to GND or VBAT (never left floating), and LBO may be left unconnected. The core boost functionality remains fully operational. This simplifies designs where battery monitoring is handled externally or not required - such as in disposable remote controls.
