Product details
Overview
TPS61013DGS from Texas Instruments is a fixed-output 2.8 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, low-battery detection, and power-save mode - used in portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61013DGS datasheet, TPS61013DGS pinout, TPS61013DGS application, or TPS61013DGS equivalent, this page provides verified technical context, confirmed pin functions, real-world application mappings, and validated alternative options for battery-powered embedded designs requiring stable 2.8 V rail generation from low-voltage sources.
Technical Context
The TPS61013DGS implements a fixed-frequency (420–780 kHz), current-mode PWM boost 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 down to 0.8 V input, enters power-save mode below ~10 mA load to reduce quiescent current (<50 µA), and isolates load from battery during shutdown via backgate diode disconnect. Autodischarge (enabled via ADEN tied to VBAT) discharges output capacitors to <0.4 V using a 300–400 Ω internal switch.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±0.08 V (2.72–2.88 V) - tightly regulated for 2.8 V logic rails and RF front-end biasing. |
| Input Voltage Range | 0.8 V to 3.3 V - supports NiCd/NiMH/alkaline single- or dual-cell operation including deep discharge recovery. |
| Max Output Current | 200 mA at VIN ≥ 1.8 V - sufficient for MCU + sensor + BLE transceiver subsystems in compact wearables. |
| Switch Current Limit | 0.85–0.93 A - sets inductor peak current and defines minimum L1 value (10–33 µH) for stable operation. |
| Quiescent Current | 31–46 µA - enables multi-week standby in battery-gated IoT endpoints without compromising startup capability. |
| Oscillator Frequency | 420–780 kHz - balances EMI control and inductor size; supports low-EMI discontinuous mode at light loads. |
| Shutdown Current | 1–3 µA - minimizes battery drain during system sleep, critical for long-life portable medical devices. |
| Low-Battery Threshold | 500 mV ±20 mV on LBI - allows precise battery state-of-charge monitoring with external resistor divider. |
Pinout & Package
TPS61013DGS 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 in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 EN | Chip-enable input | Active-high enable: tie to VBAT for always-on; pull to GND to fully disable regulator and isolate load from battery. |
| 2 COMP | Compensation node | Connect R-C-C network to stabilize control loop; sets phase margin and transient response for specific L1/COUT values. |
| 3 FB | Feedback input | Not connected - TPS61013DGS has internal 2.8 V reference; FB pin is unused in fixed-output variants. |
| 4 GND | Power ground | Main return path for SW, VOUT, and internal circuits; must be low-impedance connection to thermal pad. |
| 5 VOUT | Regulated output | 2.8 V supply rail; requires 10–47 µF ceramic output capacitor (X7R/X5R) for stability and ripple suppression. |
| 6 VBAT | Battery input | Primary power source; accepts 0.8–3.3 V; UVLO disables startup below ~0.7 V to prevent malfunction. |
| 7 SW | Switch node | Connects to inductor (L1); carries pulsed current up to 0.93 A; requires short, low-inductance trace routing. |
| 8 ADEN | Autodischarge enable | Tie to VBAT to discharge COUT to <0.4 V during shutdown; tie to GND to disable autodischarge function. |
| 9 LBI | Low-battery input | Monitor battery voltage via resistive divider; triggers LBO when scaled voltage drops below 500 mV. |
| 10 LBO | Low-battery open-drain output | Active-low flag; requires external pull-up to VOUT; signals microcontroller when battery falls below threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated NMOS/PMOS switches replace external Schottky diode - eliminates 0.3–0.4 V forward drop, enabling >95% peak efficiency at 200 mA. |
| Autodischarge function | 300–400 Ω internal switch discharges output capacitor to <0.4 V after shutdown - prevents residual voltage from corrupting MCU reset or memory state. |
| Load isolation during shutdown | Backgate diode disconnect circuit blocks reverse current flow from VOUT to VBAT - ensures zero battery drain and defined power-off behavior. |
| Power-save mode | Reduces switching frequency at light loads (<10 mA) - maintains >85% efficiency while cutting quiescent current to 31–46 µA. |
| Integrated antiringing switch | Suppresses inductor flyback ringing at SW node - reduces EMI and improves reliability without external snubber components. |
| Low-battery comparator | 500 mV ±20 mV threshold with 10 mV hysteresis on LBI - enables accurate, noise-immune battery monitoring with simple resistor divider. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61014DGS | Fixed 3.0 V output; identical pinout, package, and electrical specs except VO and FB handling. | Used where system requires 3.0 V logic rail instead of 2.8 V - e.g., certain RF transceivers or SD card interfaces. | Select TPS61014DGS only if 3.0 V regulation is mandatory; not a drop-in replacement due to different output voltage. |
| TPS61022DRVR | Higher 2.5 A switch current, 2.5–5.5 V input, 3.3/5.0 V output options; 6-pin WSON package; no LBI/LBO or ADEN. | Targets higher-power applications like motor drivers or multi-rail PMICs; lacks battery monitoring and autodischarge features. | Choose TPS61022DRVR for >500 mA loads or wider input range; avoid if low-battery detection or controlled shutdown is required. |
Compared with TPS61013DGS, TPS61014DGS offers identical form-factor and feature set but targets 3.0 V systems, while TPS61022DRVR trades battery-aware functions for higher current and broader input range - making TPS61013DGS optimal for compact, battery-state-aware 2.8 V applications.

FAQ
What is the exact output voltage tolerance of the TPS61013DGS?
The TPS61013DGS delivers a fixed 2.8 V output with ±0.08 V tolerance (2.72 V to 2.88 V) under recommended operating conditions (VIN = 1.2 V, IO = 0–100 mA, TA = 25°C). This specification is confirmed in the Electrical Characteristics table of the SLVS314F datasheet and applies across the full temperature range (–40°C to 85°C).
Can the TPS61013DGS start up from a single 0.9 V alkaline cell?
Yes, the TPS61013DGS starts up into full load with supply voltages as low as 0.9 V and remains operational down to 0.8 V input. This capability is explicitly stated in the Features section and verified in Figure 12 (Minimum Startup Supply Voltage vs Load Resistance) of the SLVS314F datasheet.
How does the autodischarge function work on the TPS61013DGS?
The TPS61013DGS discharges its output capacitor to <0.4 V after shutdown when ADEN is tied to VBAT. An internal 300–400 Ω switch connects VOUT to GND, with discharge time determined by total output capacitance. If ADEN is grounded, autodischarge is disabled - preserving residual voltage for fast wake-up.
Is the TPS61013DGS pin-compatible with other TPS6101x variants?
Yes, all TPS6101x devices in the DGS (10-pin MSOP) package share identical pin configuration and mechanical footprint. TPS61013DGS, TPS61014DGS, and TPS61015DGS differ only in fixed output voltage (2.8 V, 3.0 V, 3.3 V) and marking - enabling layout reuse across voltage variants in the same design family.
What is the maximum continuous output current supported by the TPS61013DGS?
The TPS61013DGS supports up to 200 mA continuous output current when input voltage is ≥1.8 V, as specified in the Recommended Operating Conditions table (Section 7.3). At lower inputs (0.8 V < VIN < 1.8 V), maximum output current is reduced to 100 mA to maintain regulation and thermal safety.
