Product details
Overview
TPS61010DRCRG4 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 a 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 required), and features autodischarge, low-battery detection, and power-save mode for portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61010DRCRG4 datasheet, TPS61010DRCRG4 pinout, TPS61010DRCRG4 application, or TPS61010DRCRG4 equivalent, key selection considerations include minimum start-up voltage (0.8 V), integrated 300-Ω autodischarge switch, 500-mV LBI threshold with 10-mV hysteresis, 420–780-kHz fixed-frequency PWM control, and QFN-10 package thermal resistance (RθJA = 43.1°C/W).
Technical Context
The TPS61010DRCRG4 implements a fixed-frequency, current-mode PWM boost controller with pulse-by-pulse switch current limiting (1.07–1.13 A typical) and internal slope compensation. Its synchronous rectifier uses integrated NMOS/PMOS switches (rDS(on) ≤ 0.51 Ω / 0.54 Ω at VO = 1.5 V) to eliminate external diode losses and achieve >95% peak efficiency.
Control loop stability requires external R-C-C compensation on the COMP pin; feedback regulation uses a precision 500-mV ±20-mV reference at FB. The device enters power-save mode below light load thresholds, reducing switching frequency while maintaining output regulation via burst-mode pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage range | Adjustable 1.5 V to 3.3 V via external resistor divider - enables flexible rail generation for mixed-voltage subsystems. |
| Minimum start-up voltage | 0.8 V - supports operation down to deeply discharged alkaline/NiMH cells without external bias. |
| Max output current | 200 mA at VIN ≥ 1.8 V - sufficient for powering microcontrollers, sensors, and RF transceivers in compact wearables. |
| Oscillator frequency | 420–780 kHz - balances EMI performance and inductor size; fixed-frequency operation simplifies EMI filtering. |
| Quiescent current | 5 µA shutdown current (typical) - minimizes battery drain during system sleep states. |
| Autodischarge resistance | 300 Ω (typical) - discharges output capacitors to <0.4 V within milliseconds after EN deactivation, preventing MCU latch-up. |
| LBI threshold voltage | 500 mV ±20 mV - allows precise low-battery warning with external resistive divider; 10-mV hysteresis prevents chatter. |
Pinout & Package
TPS61010DRCRG4 is housed in a thermally enhanced 3 mm × 3 mm, 10-pin QFN package (DRC) with exposed thermal pad. This package delivers RθJA = 43.1°C/W and RθJB = 18.1°C/W, enabling high-power-density designs without heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Chip-enable input | Active-high logic control: ties to GND for full shutdown (1 µA IOFF); connects to VBAT or MCU GPIO for system-level power sequencing. |
| VBAT (Pin 6) | Battery supply input | Accepts 0.8–3.3 V input; includes UVLO (≈0.7 V) to prevent erratic startup from weak cells. |
| SW (Pin 7) | Switch node | Connects to inductor; handles pulsed 1.07–1.13 A peak current; requires low-ESR ceramic capacitor and careful layout to minimize ringing. |
| VOUT (Pin 5) | Regulated output | Delivers stable 1.5–3.3 V; supplies downstream logic, sensors, or RF ICs; isolated from VBAT during shutdown. |
| FB (Pin 3) | Feedback input | Monitors output via resistor divider; 500-mV reference sets regulation point; high-impedance (0.03 µA bias) minimizes divider current loss. |
| COMP (Pin 2) | Compensation node | Requires external R-C-C network to stabilize control loop; placement critical for transient response and phase margin. |
| ADEN (Pin 8) | Autodischarge enable | Connect to VBAT to activate 300-Ω discharge path; tie to GND to disable - essential for systems requiring residual VOUT retention. |
| LBI (Pin 9) | Low-battery input | Accepts scaled battery voltage; comparator triggers LBO when input falls below 500 mV; must not float. |
| LBO (Pin 10) | Low-battery open-drain output | Active-low flag (VOL ≤ 0.2 V @ 10 µA); requires external pullup to VOUT for MCU interrupt signaling. |
| GND (Pin 4) | Power ground | Primary return path; connects to thermal pad for optimal heat dissipation and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated NMOS/PMOS switches replace external Schottky diode, eliminating 0.3–0.4 V forward drop and enabling >95% peak efficiency at 100 mA. |
| Power-save mode | Automatic transition to burst-mode operation below ~10 mA load, reducing switching losses and maintaining >85% efficiency at light loads. |
| Load isolation during shutdown | Dedicated circuit disconnects VOUT from VBAT when EN = GND, preventing battery drain through back-gate diodes of synchronous switches. |
| Integrated antiringing switch | Clamps SW node voltage spikes during turn-off, reducing EMI and eliminating need for external snubber networks. |
| Low-battery comparator | Configurable 500-mV threshold with 10-mV hysteresis and open-drain LBO output - enables accurate state-of-charge monitoring without external comparators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61016DRCR | Fixed 3.3-V output; identical pinout, package, and quiescent current; no FB/COMP pins required. | Eliminates external feedback resistors but lacks output voltage flexibility; suitable only for 3.3-V-only systems. | Select TPS61016DRCR when output voltage is fixed and board space for FB divider is constrained. |
| TPS61291DRVR | Lower 0.7-V start-up, 1.2-A switch limit, 1.2-MHz switching, and 1.4-µA shutdown current; 6-pin WSON package. | Higher integration (integrated inductor option available), smaller footprint, but requires different PCB layout and compensation. | Choose TPS61291DRVR for next-gen ultra-low-power designs prioritizing minimal solution size and sub-1-µA shutdown. |
Compared with TPS61010DRCRG4, TPS61016DRCR offers plug-and-play 3.3-V regulation but sacrifices adjustability, while TPS61291DRVR provides superior ultra-low-power performance and higher frequency at the cost of redesign effort and reduced maximum output current headroom.

FAQ
What is the minimum input voltage required for TPS61010DRCRG4 to start switching?
The TPS61010DRCRG4 starts switching at a minimum input voltage of 0.8 V under recommended operating conditions. At 25°C with 100-mA load, the typical start-up voltage is 0.9 V. Below 0.8 V, undervoltage lockout (UVLO) disables operation to prevent unstable regulation. This enables reliable function with nearly depleted alkaline or NiMH cells.
How does the autodischarge function work on TPS61010DRCRG4, and how is it enabled?
The autodischarge function on TPS61010DRCRG4 activates an internal 300-Ω switch between VOUT and GND after EN is pulled low, discharging output capacitance to <0.4 V. It is enabled by connecting ADEN (Pin 8) to VBAT; tying ADEN to GND disables the feature. This prevents unintended MCU wake-up or memory corruption during system shutdown.
Can TPS61010DRCRG4 be used with a fixed output voltage, or is it only adjustable?
TPS61010DRCRG4 is specifically the adjustable-output variant of the TPS6101x family, supporting 1.5–3.3 V via external resistor divider on FB (Pin 3). Fixed-output versions (e.g., TPS61011–TPS61016) exist but are distinct part numbers with different markings and internal feedback networks - TPS61010DRCRG4 itself requires external resistors for regulation.
What thermal performance can be expected from the TPS61010DRCRG4 QFN package?
The TPS61010DRCRG4 in its 3 mm × 3 mm QFN (DRC) package achieves RθJA = 43.1°C/W and RθJB = 18.1°C/W with standard JEDEC 2-layer board layout. With proper thermal pad soldering and copper pour, it sustains 200-mA output continuously at 85°C ambient without derating - significantly outperforming the MSOP variant (RθJA = 161.8°C/W).
Does TPS61010DRCRG4 require external compensation components, and where are they connected?
Yes, TPS61010DRCRG4 requires external R-C-C compensation on the COMP pin (Pin 2) to stabilize the current-mode control loop. A typical network includes a series RC from COMP to GND plus a small capacitor from COMP to FB. Incorrect compensation causes oscillation or poor transient response - TI's TPS6101xEVM-157 reference design provides validated values.
