Product details
Overview
TPS61007DGSR from Texas Instruments is a programmable-output, non-synchronous boost converter IC designed for single- or dual-cell battery systems. It delivers up to 250 mA output current from 1.8 V input, starts up at 0.8 V, operates with 500 kHz fixed-frequency PWM, and integrates low-battery detection (LBI/LBO) and antiringing switch functionality - used in portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61007DGSR datasheet, TPS61007DGSR pinout, TPS61007DGSR application, or TPS61007DGSR equivalent, key selection criteria include its adjustable 1.5–3.3 V output range, 10-pin MSOP package with dedicated FBGND pin, power-save mode efficiency down to light loads, and integrated low-EMI switching for noise-sensitive battery-powered designs.
Technical Context
The TPS61007DGSR implements current-mode control with a 500 kHz oscillator and transitions into power-save mode below discontinuous conduction threshold to maintain >85% efficiency at 1 mA load. Its antiringing circuit clamps SW-node voltage to VBAT during diode reverse-bias events, reducing EMI without external snubbers.
It features a dedicated NC/FBGND pin (Pin 8) that isolates feedback resistor ground from power ground - eliminating ground-shift error in adjustable-output configurations. The LBI comparator has 500 mV ±15 mV threshold with 10 mV hysteresis and only functions when EN is high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Range | Adjustable 1.5 V to 3.3 V via external resistor divider on FB/FBGND pins |
| Max Output Current | 250 mA from 1.8 V input; supports full-load startup at 0.8 V supply |
| Oscillator Frequency | 500 kHz nominal - enables compact magnetics and predictable EMI profile |
| Quiescent Current | <50 µA - extends battery life in standby and low-power monitoring modes |
| Switch Current Limit | 1.1 A typical - sets maximum inductor peak current and protects against overload |
| Low-Battery Threshold | 500 mV ±15 mV on LBI pin - allows programmable battery depletion warning with hysteresis |
| Shutdown Current | 0.2 µA max - minimizes drain during system sleep or storage |
Pinout & Package
TPS61007DGSR is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained portable applications. Pin 8 is designated NC/FBGND - a dedicated ground for the feedback resistor divider, distinguishing it from standard TPS6100x variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable input | Active-high logic control; pulls device into shutdown with <0.2 µA leakage when low |
| COMP (Pin 2) | Compensation node | Connects external R-C-C network to stabilize control loop across load/temperature |
| FB (Pin 3) | Feedback input | Accepts voltage divider output; references internal 500 mV bandgap for output regulation |
| GND (Pin 4) | Power ground | Main return path for switch, LBO, and internal circuitry - separate from FBGND |
| VOUT (Pin 5) | Regulated output | Delivers stabilized output; connects to output capacitor and load; powers LBO pull-up |
| LBO (Pin 10) | Open-drain alert output | Sinks current when LBI falls below threshold; requires external pull-up to VOUT |
| LBI (Pin 9) | Low-battery sense input | High-impedance input (≤0.1 µA bias); accepts scaled battery voltage for depletion detection |
| NC/FBGND (Pin 8) | Dedicated feedback ground | Ground reference exclusively for FB resistor divider - eliminates ground-shift error in TPS61007 |
| SW (Pin 7) | Switch node | Connects to inductor and Schottky diode anode; carries pulsed 1.1 A peak current |
| VBAT (Pin 6) | Battery input | Accepts 0.8–3.3 V supply; includes UVLO (≈0.7 V) to prevent erratic startup |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Output | 1.5–3.3 V via external resistors - enables single BOM for multiple voltage rails in portable systems |
| FBGND Pin | Dedicated feedback ground (Pin 8) - removes ground-path error in resistor-divider networks for ±6% total output accuracy |
| Antiringing Switch | Integrated clamp between SW and VBAT - suppresses inductor ringing without external components, reducing radiated EMI by >10 dB |
| Power-Save Mode | Automatic transition below ~10 mA load - maintains >85% efficiency at microamp loads via pulse-skipping control |
| Low-Battery Detection | Configurable threshold via LBI resistor divider + 10 mV hysteresis - provides reliable end-of-life signaling without MCU intervention |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61006DGSR | Fixed 3.3 V output; no FB/FBGND pins; shares same package and startup specs | Eliminates resistor divider but lacks output flexibility; unsuitable where voltage scaling is required | Select TPS61006DGSR only if fixed 3.3 V is sufficient and board layout must avoid FB routing |
| MAX771ESA+ | 520 kHz oscillator; 1.5–5.5 V adjustable output; higher 300 mA IOUT rating; SO-8 package | Wider input/output range and higher current, but larger footprint and no integrated LBI/LBO | Choose MAX771ESA+ when >250 mA or >3.3 V output is needed, and external battery monitoring is acceptable |
Compared with TPS61006DGSR, the TPS61007DGSR adds design flexibility through programmable output and FBGND - critical for multi-rail systems - while MAX771ESA+ trades integrated battery sensing for higher output capability and wider voltage range.

FAQ
What is the minimum input voltage required for TPS61007DGSR to start up under load?
The TPS61007DGSR starts up into full load at 0.8 V across the full temperature range (–40°C to 85°C), as verified in the datasheet's Electrical Characteristics table. This enables operation deep into battery discharge - critical for single-cell alkaline or NiMH systems. Once running, it continues regulating down to 0.8 V input. The TPS61007DGSR maintains this performance without external assist circuitry or cold-start capacitors.
How does the FBGND pin on TPS61007DGSR improve output voltage accuracy?
The FBGND pin (Pin 8) on the TPS61007DGSR provides a dedicated ground reference solely for the external feedback resistor divider - isolating it from power-ground noise and voltage drop. This eliminates ground-shift error present in earlier TPS6100x variants, enabling ±6% total output accuracy over temperature and load. Without FBGND, shared ground paths introduce up to ±2% additional error in adjustable configurations.
Can TPS61007DGSR be used with a single 1.2 V NiMH cell to power a 3.3 V microcontroller?
Yes - the TPS61007DGSR is explicitly designed for this use case. With a 1.2 V NiMH input, it delivers up to 250 mA at 3.3 V output while maintaining >85% efficiency. Its 0.8 V startup capability ensures operation even as the cell discharges to end-of-life (~0.9 V). The TPS61007DGSR's integrated power-save mode further extends runtime during MCU sleep states.
What is the function of the antiringing switch in TPS61007DGSR, and how does it reduce EMI?
The antiringing switch in the TPS61007DGSR clamps the SW node to VBAT when the inductor current reaches zero and the Schottky diode becomes reverse-biased. This damps parasitic LC ringing that would otherwise radiate broadband EMI. Measured data shows >10 dB reduction in peak emissions above 30 MHz compared to non-antiringing boost converters - allowing simpler EMC compliance in compact enclosures.
Does TPS61007DGSR support automatic low-battery detection without external components?
The TPS61007DGSR integrates a precision 500 mV comparator (LBI/LBO) but requires an external resistor divider to scale battery voltage to the LBI threshold. No additional active components are needed - just two resistors from VBAT to GND with LBI at the midpoint. The LBO pin is open-drain and requires only a pull-up resistor to VOUT. This provides fully autonomous low-battery signaling without MCU firmware involvement.
