Product details
Overview
TPS61006DGSR from Texas Instruments is a fixed-output 3.3 V, non-synchronous boost converter optimized for single- or dual-cell battery systems. It delivers up to 100 mA from 0.8 V input, starts up into full load at 0.9 V, operates with ≤50 µA quiescent current, and integrates low-battery detection (LBI/LBO) for system-level power management in portable medical and audio devices.
For engineers reviewing the TPS61006DGSR datasheet, TPS61006DGSR pinout, TPS61006DGSR application, or TPS61006DGSR equivalent, key selection criteria include minimum startup voltage (0.9 V), fixed 3.3 V output tolerance (±3.3% over load/temperature), integrated antiringing switch for EMI reduction, and MSOP-10 package compatibility with space-constrained battery-powered designs.
Technical Context
The TPS61006DGSR uses a fixed-frequency (500 kHz) current-mode PWM controller with automatic transition into power-save mode below ~10 mA load to sustain >85% efficiency across 1–100 mA. Its internal 1.1 A switch current limit and UVLO (0.7 V) ensure robust start-up and brownout protection during battery discharge.
It implements an integrated antiringing switch that clamps SW-node ringing to VBAT when the inductor current reaches zero, reducing radiated EMI without external snubbers. The LBI/LBO comparator provides programmable low-battery warning with 500 mV threshold and 10 mV hysteresis, active only when EN is high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±3.3% (measured at 100 mA, 0.8–1.6 V input) |
| Startup Input Voltage | 0.9 V into 33 Ω load (enables operation from near-dead alkaline/NiMH cells) |
| Max Output Current | 100 mA @ 0.8 V input; 250 mA @ 1.8 V input (supports dual-cell configurations) |
| Quiescent Current | <50 µA (minimizes standby drain in always-on remote controls or sensors) |
| Oscillator Frequency | 500 kHz typical (enables compact 33 µH inductor and ceramic output capacitor) |
| Switch Current Limit | 1.1 A (prevents inductor saturation; requires ≥1.5× peak current rating on external inductor) |
| Efficiency Peak | 90% @ 100 mA, 1.2 V input, 3.3 V output (reduces thermal load in sealed enclosures) |
Pinout & Package
TPS61006DGSR is housed in a 10-pin VSSOP (DGS) package, 3.00 mm × 3.00 mm body size, with 0.5 mm pitch and exposed thermal pad (not electrically connected). Pin 1 is EN; pin 10 is LBO. NC/FBGND (pin 8) is not connected on TPS61006DGSR.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (1) | Chip-enable input | Active-high logic control: tie to VBAT for always-on; pull to GND for shutdown (<0.5 µA drain) |
| COMP (2) | Error amplifier compensation node | Connect R-C-C network to stabilize loop response; critical for transient load regulation |
| FB (3) | Feedback input | No connection required - TPS61006DGSR has internal resistor divider for fixed 3.3 V output |
| GND (4) | Power ground | Main return path for switch current and analog circuitry; connect directly to thermal pad |
| VOUT (5) | Regulated output | 3.3 V supply rail; decouple with ≥22 µF ceramic capacitor close to pin |
| LBO (10) | Open-drain low-battery output | Pulled low when LBI < 500 mV; requires external pullup to VOUT for active-low flag signaling |
| LBI (9) | Low-battery input | Monitor battery via resistive divider; connect to GND if unused (never float) |
| SW (7) | Switch node | Connects to inductor/diode junction; high dv/dt node requiring tight layout and guard ring |
| VBAT (6) | Battery input | Accepts 0.8–3.3 V; bypass with ≥10 µF ceramic capacitor adjacent to pin |
| NC/FBGND (8) | No-connect | Not bonded internally on TPS61006DGSR; leave unconnected or float (no PCB trace) |
Key Features
| Feature | Design Value |
|---|---|
| Start-up into full load | Operates from 0.9 V input with 33 Ω load - enables use with deeply discharged NiMH/alkaline cells |
| Integrated low-battery comparator | 500 mV threshold with 10 mV hysteresis on LBI; LBO provides open-drain system alert without external IC |
| Antiringing switch | Internally clamps SW-node ringing to VBAT during DCM - reduces EMI by >10 dB without snubber components |
| Power-save mode | Disables switching below ~10 mA load - maintains >80% efficiency at 1 mA output current |
| Micro-size packaging | 3 mm × 3 mm VSSOP-10 footprint - fits in <100 mm² PCB area for hearing aids and wearables |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61022RGET | Higher 2.5 A switch limit; 2.5 V–5.5 V input; synchronous rectification; 1.2 MHz switching | Targets higher-current (up to 2 A) loads; requires different inductor/capacitor values and layout | Choose for >200 mA output or wider input range; not drop-in due to pinout and control scheme differences |
| MAX17065ETA+ | 0.7 V startup; 3.3 V fixed output; 1.2 MHz; integrated Schottky; 1.2 A switch | Optimized for ultra-low-voltage Li-ion backup; lacks LBI/LBO pins | Prefer when lowest possible startup voltage is critical and low-battery monitoring is handled externally |
Compared with TPS61006DGSR, TPS61022RGET supports higher output current but requires PCB redesign and lacks integrated battery monitoring, while MAX17065ETA+ achieves lower startup voltage at the cost of no built-in low-battery signaling - making TPS61006DGSR optimal for cost-sensitive, space-constrained, battery-supervised portable devices.

FAQ
What is the minimum input voltage required for TPS61006DGSR to start up under load?
The TPS61006DGSR starts up into a full 33 Ω load at 0.9 V input voltage across the full –40°C to +85°C temperature range. Once running, it continues operation down to 0.8 V input. This specification is verified per SLVS279D Section 7.5 and applies only when EN is high and LBI is properly terminated.
Does TPS61006DGSR require external feedback resistors to set its output voltage?
No. TPS61006DGSR has an internal resistor divider that fixes the output voltage at 3.3 V. The FB pin (pin 3) must be left unconnected. External resistors are only required for adjustable-output variants like TPS61000 or TPS61007 - not for TPS61006DGSR.
How does the low-battery detection function work on TPS61006DGSR?
The TPS61006DGSR uses the LBI pin to monitor battery voltage via an external resistor divider. When the divided voltage drops below 500 mV ±15 mV, the LBO pin pulls low (open-drain). This function is active only when EN = high; LBO is high-impedance in shutdown. LBI must never be left floating.
What is the purpose of the COMP pin on TPS61006DGSR, and how should it be configured?
The COMP pin on TPS61006DGSR is the error amplifier compensation node. It requires an external R-C-C network (e.g., 10 kΩ, 1 nF, 100 pF) connected to GND to stabilize the control loop and ensure proper transient response. Incorrect compensation causes output overshoot or oscillation - design guidance is provided in SLVS279D Section 10.2.2.1.
Can TPS61006DGSR be used with a single-cell NiMH battery that discharges down to 0.8 V?
Yes. TPS61006DGSR sustains regulation down to 0.8 V input voltage once started, and starts reliably at 0.9 V into full load. This matches the discharge curve of single-cell NiMH (1.2 V nominal, 0.8–1.4 V operational), enabling full utilization of battery capacity without premature cutoff.
