Product details
Overview
TPS61010DGSR from Texas Instruments is a high-efficiency, adjustable-output synchronous boost converter IC 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 via external resistor divider, integrates synchronous rectification (no external Schottky diode required), and features autodischarge, low-battery detection, and shutdown isolation - used in portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61010DGSR datasheet, TPS61010DGSR pinout, TPS61010DGSR application, or TPS61010DGSR equivalent, this page provides verified technical context, validated pin functions, confirmed efficiency and startup behavior, real-world application constraints (e.g., 0.8 V minimum operating voltage, 300 Ω autodischarge switch resistance), and two rigorously cross-checked alternative parts with documented functional and packaging differences.
Technical Context
The TPS61010DGSR implements a fixed-frequency (420–780 kHz), current-mode PWM boost controller with integrated NMOS/PMOS synchronous rectifier, enabling >95% peak efficiency and eliminating external diode requirements. Its pulse-by-pulse current limiting caps switch current at 1.07–1.13 A (typical) and enforces strict 0.8 V minimum operating input voltage.
It operates in powersave mode below light load thresholds, dynamically reducing switching frequency to maintain high efficiency down to microamp quiescent levels (<50 µA). The ADEN pin enables/disables autodischarge (300–400 Ω internal switch), while LBI/LBO provide user-programmable low-battery detection referenced to 500 mV ±15 mV with 10 mV hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Range | Adjustable 1.5 V to 3.3 V via external FB resistor divider - enables flexible rail generation across diverse low-voltage subsystems. |
| Input Voltage Range | Operates from 0.8 V to 3.6 V - supports deep discharge of NiCd/NiMH/alkaline cells without brownout. |
| Max Output Current | 200 mA at VIN ≥ 1.8 V - sufficient to power MCU cores, RF transceivers, or sensor interfaces directly. |
| Switch Current Limit | 1.07 A typical - sets hard ceiling on inductor peak current, defining minimum L1 value and thermal design margin. |
| Quiescent Current | 31–46 µA typical (VBAT/SW pins) - minimizes standby drain in always-on battery applications. |
| Oscillator Frequency | 420–780 kHz - balances EMI control, inductor size, and efficiency across load conditions. |
| Autodischarge Resistance | 300–400 Ω - determines discharge time constant with output capacitance; residual VOUT < 0.4 V after shutdown. |
| Feedback Reference | 480–520 mV - defines precision of output regulation when using external resistor divider on FB pin. |
Pinout & Package
TPS61010DGSR is packaged in a 10-pin MSOP (DGS) package measuring 3.00 mm × 3.00 mm, with exposed thermal pad for enhanced heat dissipation. Pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Chip-enable input | Active-high digital enable; pulls internal control logic and LBI comparator offline when low - ensures zero-load battery isolation. |
| 2 - COMP | Compensation node | Connects external R-C-C network to stabilize control loop; directly affects transient response and phase margin. |
| 3 - FB | Feedback input | Senses output voltage divider ratio; sets regulated VOUT for TPS61010 (adjustable version); must be left unconnected for fixed-output variants. |
| 4 - GND | Power ground | Primary return path for SW, VOUT, and internal bias currents; connects to thermal pad for thermal conduction. |
| 5 - VOUT | Regulated output | Delivers stabilized output voltage; supplies downstream loads and feeds LBO pull-up; requires 10–47 µF ceramic output capacitor. |
| 6 - VBAT | Battery input | Accepts 0.8–3.6 V supply; powers internal circuitry and SW driver; UVLO triggers shutdown below ~0.7 V. |
| 7 - SW | Switch node | Connects to inductor; carries pulsed high-side current; requires low-ESR ceramic input cap (≥10 µF) placed near pin. |
| 8 - ADEN | Autodischarge enable | High = enable discharge path to GND during shutdown; low = disable - prevents unintended system reset on wake-up. |
| 9 - LBI | Low-battery input | Accepts scaled battery voltage; comparator trips at 480–520 mV threshold - requires resistive divider for custom cutoff voltage. |
| 10 - LBO | Low-battery open-drain output | Active-low flag; requires external pull-up to VOUT; asserts when LBI falls below threshold - signals host MCU to initiate battery save mode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61022DRVR | Fixed 3.3 V output; 2.5 A switch current limit; 1.8–5.5 V input range; 2.0 mm × 2.0 mm WSON package. | Not adjustable; higher current capability but lacks LBI/LBO and autodischarge - unsuitable for battery monitoring or controlled shutdown. | Select TPS61022DRVR only when fixed 3.3 V, higher output current, and smaller footprint are prioritized over programmability and battery management features. |
| MAX17222ETA+ | Adjustable 2.0–5.25 V output; 500 mA max output; 0.4 V start-up; 1.6 mm × 1.6 mm TDFN package; no LBI/LBO. | Lower start-up voltage (0.4 V) and higher output current, but no integrated low-battery detection or autodischarge function. | Choose MAX17222ETA+ for ultra-low-voltage harvesting or higher-current needs where battery state signaling is handled externally. |
Compared with TPS61010DGSR, TPS61022DRVR trades adjustability and battery supervision for higher current and smaller size, while MAX17222ETA+ offers lower start-up voltage and greater output current but omits critical battery interface features - making TPS61010DGSR uniquely suited for cost-sensitive, feature-complete single/dual-cell portable systems requiring full battery-aware power management.

FAQ
What is the minimum input voltage required for TPS61010DGSR to start up?
The TPS61010DGSR starts up into full load at a minimum input voltage of 0.9 V (typical) with RL = 3 kΩ at TA = 25°C, and can operate continuously down to 0.8 V once started. This enables reliable operation from deeply discharged NiCd, NiMH, or alkaline cells - a key requirement for long-runtime portable devices like pagers and remote controls. The device incorporates undervoltage lockout (UVLO) that disables operation below ~0.7 V to prevent malfunction.
How does the autodischarge function work on the TPS61010DGSR?
The autodischarge function on the TPS61010DGSR activates when the ADEN pin is tied to VBAT, connecting an internal 300–400 Ω switch between VOUT and GND during shutdown (EN = low). This discharges output capacitors to <0.4 V, preventing residual voltage from causing microcontroller latch-up or memory corruption - especially critical in portable medical diagnostics and internet audio players. Tying ADEN to GND disables this feature.
Can the TPS61010DGSR be used with a fixed output voltage, or is it only adjustable?
The TPS61010DGSR is the adjustable-output variant in the TPS6101x family, supporting 1.5 V to 3.3 V via external resistor divider on the FB pin. Fixed-output versions (e.g., TPS61011–TPS61016) exist but are distinct part numbers. For TPS61010DGSR, the FB pin must be used with a precision divider; leaving it unconnected results in undefined regulation - unlike fixed-output siblings where FB is NC.
What is the purpose of the LBI and LBO pins on the TPS61010DGSR?
The LBI (low-battery input) and LBO (low-battery output) pins implement a user-programmable battery monitor: LBI accepts a scaled battery voltage (e.g., via resistor divider), and when it drops below 480–520 mV, LBO pulls low as an open-drain flag. This enables host MCUs to trigger battery-save routines or user alerts. The circuit is active only when EN = high; LBI must never float and should be tied to GND or VBAT if unused.
Does the TPS61010DGSR require an external Schottky diode?
No, the TPS61010DGSR does not require an external Schottky diode because it integrates a synchronous rectifier using NMOS and PMOS switches. This architecture achieves >95% peak efficiency and eliminates reverse recovery losses and associated thermal stress. The internal rectifier also enables full load isolation during shutdown - a feature impossible with discrete diode-based boost converters.
