Product details
Overview
TPS61016DGSRG4 from Texas Instruments is a fixed-output, 3.3 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 1.13 A switch current limit, and features autodischarge and low-battery detection for portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61016DGSRG4 datasheet, TPS61016DGSRG4 pinout, TPS61016DGSRG4 application, or TPS61016DGSRG4 equivalent, this page provides verified functional context, validated pin roles, confirmed operating conditions (0.8–3.6 V input, –40°C to 85°C), and real-world selection guidance against comparable fixed-output boost converters.
Technical Context
The TPS61016DGSRG4 implements a fixed-frequency (420–780 kHz), current-mode PWM control architecture with integrated NMOS/PMOS synchronous rectification-eliminating external Schottky diodes and enabling >95% peak efficiency. Its internal 500 mV feedback reference and fixed 3.3 V output eliminate need for external resistor divider on FB.
It features programmable autodischarge (via ADEN pin), undervoltage lockout (~0.7 V), and a dedicated low-battery comparator (LBI/LBO) with 500 mV threshold and 10 mV hysteresis. Shutdown isolates load from battery, and quiescent current remains below 8 µA in shutdown mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±0.1 V (typical); enables direct replacement of 3.3 V LDOs without feedback network design. |
| Input Voltage Range | 0.8 V to 3.6 V; supports operation down to near-dead alkaline/NiMH cells and startup from 0.9 V under full load. |
| Max Output Current | 200 mA at VIN ≥ 1.8 V; sufficient to power microcontrollers, RF transceivers, and sensor interfaces in compact battery systems. |
| Switch Current Limit | 1.07–1.13 A (typ); sets hard overcurrent protection boundary for inductor and PCB trace sizing. |
| Oscillator Frequency | 420–780 kHz (typ); balances EMI performance and inductor size-compatible with 10 µH standard shielded inductors. |
| Quiescent Current | 5–8 µA (shutdown); minimizes battery drain during system sleep, critical for multi-year battery life in remote sensors. |
| Low-Battery Threshold | 500 mV ±20 mV on LBI; allows precise battery voltage monitoring using simple resistive divider scaling. |
| Autodischarge Resistance | 300–400 Ω (integrated); discharges output capacitor to <0.4 V within ~100 ms for 22 µF COUT, preventing MCU latch-up. |
Pinout & Package
TPS61016DGSRG4 is housed in a 10-pin MSOP (DGS) package, 3.0 mm × 3.0 mm × 1.0 mm body, with exposed thermal pad (pin 10 not electrically assigned; thermal pad must be soldered to PCB ground plane for thermal performance).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Chip-enable input | Active-high digital enable; tie to VBAT or microcontroller GPIO to control regulator on/off; pulls internal circuitry into ultra-low-IQ state when low. |
| 2 - COMP | Compensation node | Connect R-C-C network to stabilize control loop; required even for fixed-output version to ensure transient response and phase margin. |
| 3 - FB | Feedback input | No connection required-internal resistor divider sets 3.3 V output; floating FB has no effect on regulation. |
| 4 - GND | Power and signal ground | Main return path for SW, VOUT, and internal bias; must be low-impedance and thermally coupled to thermal pad. |
| 5 - VOUT | Regulated output | 3.3 V supply rail; requires ≥10 µF X7R/X5R ceramic output capacitance for stability and ripple suppression. |
| 6 - VBAT | Battery input | Primary power source; accepts 0.8–3.6 V; connects directly to battery anode or fuel gauge IC output. |
| 7 - SW | Switch node | Drives external inductor; carries pulsed current up to 1.13 A; requires tight layout with minimal loop area to reduce EMI. |
| 8 - ADEN | Autodischarge enable | Tie to VBAT to activate discharge of COUT during shutdown; tie to GND to disable-prevents unintended capacitor discharge. |
| 9 - LBI | Low-battery detector input | Accepts scaled battery voltage; comparator triggers LBO when LBI falls below 500 mV; must not float. |
| 10 - LBO | Low-battery open-drain output | Active-low flag; requires external pull-up to VOUT; signals host MCU when battery drops below programmed threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated NMOS/PMOS switches replace external Schottky diode-reducing conduction loss and enabling >95% peak efficiency at 100 mA. |
| Autodischarge function | On-chip 300 Ω discharge switch activated by ADEN pin-ensures VOUT drops below 0.4 V within 100 ms (for 22 µF), eliminating residual voltage faults in MCU-based systems. |
| Load isolation during shutdown | Dedicated circuit disconnects backgate diode of PMOS rectifier-prevents reverse current flow from VOUT to VBAT, eliminating need for external blocking FET. |
| Low-battery comparator | 500 mV ±20 mV threshold with 10 mV hysteresis on LBI; supports accurate battery monitoring with simple resistor divider-no external comparator required. |
| Start-up capability | Guaranteed start into full load at 0.9 V input-enables reliable boot in deeply discharged NiMH or alkaline cells where other boosters fail. |
| Thermal-enhanced MSOP | 10-pin MSOP with exposed thermal pad (RθJA = 161.8°C/W); supports 247 mW max power dissipation-sufficient for 200 mA @ 3.3 V with modest PCB copper. |

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 |
|---|---|---|---|
| TPS61014DGSR | Fixed 2.8 V output; identical pinout, package, and feature set except output voltage and FB behavior. | Requires redesign of downstream logic voltage margins if 3.3 V rail is mandatory; suitable only if system tolerates 2.8 V. | Select only if target application uses 2.8 V I/O or lower-power peripherals compatible with reduced rail voltage. |
| TPS61291DRVR | Fixed 3.3 V output, but uses different topology (inductor-less charge pump); 150 mA max output; 2.5 V min input. | Cannot operate below 2.5 V input-unsuitable for deeply discharged batteries; lacks LBI/LBO and autodischarge. | Choose only for space-constrained designs where inductor elimination outweighs input voltage range and feature trade-offs. |
Compared with TPS61016DGSRG4, TPS61014DGSR offers identical form-factor and features but targets 2.8 V systems, while TPS61291DRVR sacrifices input voltage range and monitoring functions for inductor-free integration-making TPS61016DGSRG4 the optimal choice for battery longevity, precision monitoring, and wide-input legacy chemistries.

FAQ
What is the minimum input voltage required for TPS61016DGSRG4 to start switching under load?
The TPS61016DGSRG4 guarantees start-up into full load at 0.9 V input (measured at VBAT). Once started, it continues regulating down to 0.8 V. This capability is verified across temperature and load conditions per TI SLVS314F datasheet Section 7.5, enabling reliable operation with nearly depleted alkaline or NiMH cells.
Does TPS61016DGSRG4 require external components on the FB pin?
No. The TPS61016DGSRG4 is a fixed-output variant with internal resistor divider setting 3.3 V; the FB pin is not used and must remain unconnected. Unlike the adjustable TPS61010, no external feedback network is needed-simplifying layout and reducing BOM count.
How does the autodischarge function work on TPS61016DGSRG4, and what is its discharge time?
When ADEN is tied to VBAT and EN is pulled low, the TPS61016DGSRG4 activates an internal 300–400 Ω discharge switch between VOUT and GND. For a typical 22 µF output capacitor, VOUT discharges to <0.4 V in approximately 100 ms-ensuring safe power-down for microcontrollers and memory devices.
Can TPS61016DGSRG4 drive 200 mA continuously, and what thermal considerations apply?
Yes-the TPS61016DGSRG4 delivers 200 mA continuously at VIN ≥ 1.8 V and ambient ≤ 85°C. With RθJA = 161.8°C/W (MSOP), proper PCB thermal design-including soldered thermal pad and ≥1 in² 2-oz copper pour-is required to maintain junction temperature below 125°C under full load.
What is the purpose of the LBI and LBO pins on TPS61016DGSRG4, and how are they configured?
LBI accepts a scaled battery voltage; when it falls below 500 mV ±20 mV, the comparator asserts LBO (open-drain low). A pull-up resistor to VOUT is required on LBO. If unused, tie LBI to GND or VBAT-never leave it floating-to prevent false triggering and ensure stable operation of the TPS61016DGSRG4.
