Product details
Overview
TPS61016DGS from Texas Instruments is a high-efficiency, adjustable-output synchronous boost converter designed for single- or dual-cell battery-powered systems. It delivers up to 200 mA output current from 0.9 V input, supports programmable output voltage from 1.5 V to 3.3 V, integrates synchronous rectification (no external Schottky diode required), and features autodischarge, low-battery detection, and power-save mode - enabling reliable operation in portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61016DGS datasheet, TPS61016DGS pinout, TPS61016DGS application, or TPS61016DGS equivalent, this page provides verified technical context, validated pin functions, confirmed operating conditions (0.8 V–3.3 V input, 1.5–3.3 V adjustable output), real-world efficiency data (>95% peak), and two rigorously cross-checked alternative parts for system-level design continuity.
Technical Context
The TPS61016DGS implements a fixed-frequency (420–780 kHz), current-mode PWM boost controller with integrated NMOS/PMOS synchronous rectifier. It uses pulse-by-pulse current limiting (1.07–1.13 A typical switch current limit) and external R-C-C compensation on the COMP pin to stabilize the control loop.
It features automatic power-save mode at light loads, undervoltage lockout (UVLO ≈0.7 V), and an integrated low-battery comparator (500 mV threshold on LBI, open-drain LBO output). The autodischarge function-enabled by tying ADEN to VBAT-discharges the output capacitor via a 300–400 Ω internal switch, reducing residual VOUT to <0.4 V during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8 V to 3.3 V - enables start-up from nearly-dead alkaline/NiMH cells and stable operation down to battery end-of-life. |
| Output Voltage Range | Adjustable 1.5 V to 3.3 V - set via external resistor divider on FB pin; supports diverse logic supply requirements. |
| Max Output Current | 200 mA at VIN ≥1.8 V - sufficient to power microcontrollers, sensors, and RF front-ends in compact portable devices. |
| Switch Current Limit | 1.07–1.13 A typical - protects internal MOSFETs during transient overload or short-circuit events. |
| Quiescent Current | 5 µA typical shutdown current - minimizes battery drain during extended standby periods. |
| Oscillator Frequency | 420–780 kHz - balances EMI performance and inductor size; supports discontinuous conduction mode (DCM) with low-EMI mode. |
| Feedback Reference | 480–520 mV - precise internal bandgap reference enables accurate output regulation across temperature. |
Pinout & Package
TPS61016DGS is housed in a 10-pin MSOP (DGS) package measuring 3.00 mm × 3.00 mm with exposed thermal pad, optimized for space-constrained portable designs and efficient PCB thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Chip-enable input | Active-high enable: tie to VBAT to activate converter; tie to GND to fully disable switching and isolate load from battery. |
| FB (Pin 3) | Feedback input | Connects to resistor divider to program output voltage; internal 500 mV reference sets regulation point. |
| GND (Pin 4) | Power ground | Primary return path for power and control circuits; must be connected to thermal pad for optimal thermal performance. |
| LBI (Pin 9) | Low-battery detector input | Accepts scaled battery voltage; triggers LBO when input drops below 480–520 mV threshold. |
| LBO (Pin 10) | Open-drain low-battery output | Sinks current when LBI falls below threshold; requires external pull-up to VOUT for logic-level signaling. |
| ADEN (Pin 8) | Autodischarge enable | Tie to VBAT to activate output capacitor discharge during shutdown; tie to GND to disable. |
| COMP (Pin 2) | Error amplifier compensation | External R-C-C network sets loop stability and transient response; critical for reliable regulation. |
| SW (Pin 7) | Switch node | Connects directly to inductor; carries high di/dt switching current - requires tight layout and low-inductance routing. |
| VBAT (Pin 6) | Battery input supply | Primary power source; supports 0.8–3.3 V range with UVLO protection below ~0.7 V. |
| VOUT (Pin 5) | Regulated output | Delivers stable boosted voltage; isolated from VBAT during shutdown via integrated backgate disconnect circuit. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated synchronous rectifier | Eliminates need for external Schottky diode and achieves >95% peak efficiency - reduces BOM count and thermal stress. |
| Autodischarge function | Discharges output capacitor to <0.4 V via 300–400 Ω internal switch when EN = GND - prevents microcontroller latch-up or memory corruption. |
| Power-save mode | Reduces switching frequency at light loads to maintain high efficiency (>85% at 1 mA) without external control logic. |
| Load isolation during shutdown | Backgate diode of high-side PMOS is actively disconnected - ensures zero current path from battery to VOUT, eliminating parasitic drain. |
| Low-battery detection | Configurable threshold via LBI resistive divider; 10 mV hysteresis prevents chatter; LBO provides direct interface to MCU interrupt or reset pin. |
Applications
| Internet Audio Players | Portable Medical Diagnostic Equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61015DGS | Fixed 3.3 V output; no FB pin required; identical package and pinout except FB unconnected. | Eliminates external feedback resistors but lacks output voltage flexibility; suitable only where 3.3 V is mandatory. | Select if board layout rework is unacceptable and output voltage tolerance permits fixed 3.3 V (±3.3% vs TPS61016's ±3.0% over range). |
| TPS61291DRVR | Higher 500 mA output, 0.7 V start-up, 1.2 MHz switching, WSON-6 package; no LBI/LBO or ADEN. | Targets higher-power wearables; lacks battery monitoring and autodischarge - requires external circuitry for same functionality. | Select when >200 mA is needed and system can implement discrete low-battery detection; not drop-in due to different pin count, package, and feature set. |
Compared with TPS61016DGS, TPS61015DGS offers simpler implementation for fixed 3.3 V use but sacrifices adjustability, while TPS61291DRVR delivers higher current and smaller footprint at the cost of missing integrated battery supervision - making TPS61016DGS the optimal choice for space-constrained, battery-aware portable systems requiring programmable output and autonomous shutdown behavior.

FAQ
What is the minimum input voltage required for TPS61016DGS to start up?
The TPS61016DGS starts up with a minimum input voltage of 0.85 V (typical) under 100 mA load, and as low as 0.8 V (guaranteed) with lighter loads. This enables reliable operation from deeply discharged NiMH or alkaline cells, and is validated per Section 7.5 of the SLVS314F datasheet.
How does the autodischarge function work on TPS61016DGS?
When ADEN is tied to VBAT and EN is pulled low, the TPS61016DGS activates an internal 300–400 Ω discharge switch between VOUT and GND, reducing residual output voltage to <0.4 V. This prevents unintended MCU wake-up or memory state corruption - a verified behavior documented in Section 9.3.6 and Figure 11 of the datasheet.
Can TPS61016DGS operate with a 3.3 V fixed output without external resistors?
No - TPS61016DGS is the adjustable version of the family and requires an external resistor divider on the FB pin to set output voltage. For fixed 3.3 V, TI offers TPS61015DGS, which has identical pinout and package but internal feedback; using TPS61016DGS for fixed 3.3 V mandates proper FB divider design per Section 10.2.1.
What is the purpose of the COMP pin on TPS61016DGS?
The COMP pin on TPS61016DGS connects to an external R-C-C compensation network that stabilizes the error amplifier's control loop. Proper compensation is essential for transient response and regulation accuracy - TI provides recommended values in Application Report SLVA267 and the TPS6101xEVM-157 reference design.
Does TPS61016DGS provide true load isolation during shutdown?
Yes - TPS61016DGS uses a patented backgate disconnect circuit that isolates VOUT from VBAT when EN = GND, achieving <1 µA shutdown current. Unlike conventional synchronous boosters, it prevents reverse current flow through the PMOS body diode, ensuring zero parasitic drain - confirmed in Section 9.3.2 and Figure 17 of the datasheet.
