Product details
Overview
TPS61010DRCR 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 a 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 operates down to 0.8 V input during regulation - enabling use in ultra-low-voltage portable medical diagnostics and wireless headsets.
For engineers reviewing the TPS61010DRCR datasheet, TPS61010DRCR pinout, TPS61010DRCR application, or TPS61010DRCR equivalent, key selection considerations include its 0.8-V minimum operating voltage, integrated autodischarge function (300 Ω switch), <50 µA quiescent current, and QFN-10 (3 mm × 3 mm) package with thermal pad for compact, thermally robust designs.
Technical Context
The TPS61010DRCR implements a fixed-frequency (420–780 kHz), current-mode PWM boost controller with pulse-by-pulse switch current limiting (typ. 1.0 A). Its synchronous rectifier uses integrated NMOS/PMOS switches (rDS(on) ≤ 0.51 Ω / 0.54 Ω at VO = 1.5 V) to achieve >95% efficiency without external diodes.
It features externally compensated error amplifier (COMP pin), programmable low-battery detection via LBI/LBO (500 mV threshold), and autodischarge control via ADEN pin. During shutdown (EN = GND), load isolation is enforced and output capacitor discharge is enabled when ADEN = VBAT - reducing residual VOUT to <0.4 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage range | Adjustable 1.5 V to 3.3 V via FB resistor divider - enables flexible rail generation for diverse SoC or sensor interfaces. |
| Minimum start-up voltage | 0.9 V (typ.) - allows reliable startup from deeply discharged NiMH/alkaline cells. |
| Max continuous output current | 200 mA at VIN ≥ 1.8 V - sufficient to power microcontrollers, RF transceivers, or display drivers in portable devices. |
| Quiescent current | 46 µA (typ.) - minimizes battery drain in always-on monitoring applications. |
| Shutdown current | 1–3 µA - ensures negligible self-discharge during extended storage or sleep modes. |
| Oscillator frequency | 500 kHz (typ.) - balances EMI performance and inductor size (10–33 µH typical). |
| Switch current limit | 1.07 A (typ. at VO = 3.3 V) - sets peak inductor current and defines maximum deliverable power under low-VIN conditions. |
| Feedback reference voltage | 500 mV (±20 mV) - determines output voltage accuracy and stability with external resistor divider. |
Pinout & Package
The TPS61010DRCR is housed in a 3 mm × 3 mm, 10-pin QFN package (DRC) with exposed thermal pad for enhanced thermal dissipation in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBAT (Pin 6) | Input supply connection | Accepts 0.8–3.3 V battery input; feeds internal UVLO, bias, and power switches. |
| EN (Pin 1) | Enable control input | Active-high logic: drives converter ON/OFF; disconnects load from battery during shutdown. |
| ADEN (Pin 8) | Autodischarge enable input | High = enables 300 Ω internal discharge switch on VOUT during shutdown; low = disables discharge. |
| FB (Pin 3) | Feedback input | Connects to resistor divider from VOUT to set regulated output voltage (1.5–3.3 V range). |
| COMP (Pin 2) | Compensation node | External R-C-C network stabilizes control loop; critical for transient response and phase margin. |
| VOUT (Pin 5) | Regulated output | Delivers stable boosted voltage; requires 10–47 µF ceramic output capacitor for ripple suppression. |
| LBO (Pin 10) | Low-battery open-drain output | Active-low flag (pulled low when LBI < 500 mV); requires external pullup to VOUT. |
| LBI (Pin 9) | Low-battery sense input | Monitors scaled battery voltage; 10 mV hysteresis prevents chatter near threshold. |
| SW (Pin 7) | Power switch node | Connects to inductor; carries pulsed current up to 1.07 A; requires low-ESR layout routing. |
| GND (Pin 4) | Power and signal ground | Primary return path; must be tied directly to thermal pad for optimal thermal and noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated NMOS/PMOS switches eliminate external Schottky diode, enabling >95% efficiency and reducing BOM count. |
| Autodischarge function | 300 Ω internal switch discharges output capacitor to <0.4 V during shutdown - prevents MCU latch-up or memory corruption. |
| Powersave mode | Reduces switching frequency at light loads while maintaining regulation - sustains high efficiency down to µA-level output currents. |
| Load isolation during shutdown | Special backgate control disconnects output from battery even with PMOS body diode present - eliminates standby leakage paths. |
| Integrated low-battery comparator | 500 mV ±15 mV reference with 10 mV hysteresis enables accurate, programmable battery monitoring without external components. |
| Antiringing switch | Integrated circuit suppresses inductor ringing during switch turn-off - reduces EMI and improves reliability without snubber networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61012DRCR | Fixed 2.5 V output; no FB pin required; identical package and pinout. | Eliminates external feedback resistors but lacks output voltage flexibility. | Select when system requires only 2.5 V and board space is constrained. |
| MAX1703ESA+ | Fixed 3.3 V output; higher 2.5-A switch current limit; 1.2-MHz switching frequency. | Better suited for higher-current loads (>200 mA) but consumes more quiescent current (110 µA). | Choose for faster transient response and higher output capability where efficiency at light load is secondary. |
Compared with TPS61010DRCR, TPS61012DRCR offers plug-and-play simplicity for fixed-rail designs, while MAX1703ESA+ trades higher quiescent current for greater peak current and switching speed - making TPS61010DRCR optimal for ultra-low-power, adjustable-voltage portable systems.

FAQ
What is the minimum input voltage required for TPS61010DRCR to start up?
The TPS61010DRCR starts up with a minimum input voltage of 0.9 V (typical) under full-load conditions. This allows reliable operation from nearly depleted single-cell alkaline or NiMH batteries. Once started, it continues regulating down to 0.8 V input, as specified in the recommended operating conditions. The actual startup voltage depends on load and temperature, but remains within this range per TI's SLVS314F datasheet.
How does the autodischarge function work on the TPS61010DRCR?
The autodischarge function on the TPS61010DRCR activates when ADEN is tied to VBAT and EN is driven low. An internal 300 Ω switch connects VOUT to GND, discharging output capacitance until residual voltage falls below 0.4 V. This prevents unintended MCU wakeups or memory corruption during shutdown. If ADEN is grounded, autodischarge is disabled - preserving VOUT for fast restart.
Can the TPS61010DRCR replace fixed-output variants like TPS61012DRCR in the same PCB layout?
No - the TPS61010DRCR cannot directly replace fixed-output variants such as TPS61012DRCR without layout changes. While both share the DRC package and pinout, TPS61010DRCR requires an external resistor divider on FB to set output voltage, whereas TPS61012DRCR leaves FB unconnected. Using TPS61010DRCR in a TPS61012DRCR layout would result in undefined output voltage due to floating FB.
What is the role of the COMP pin on the TPS61010DRCR?
The COMP pin on the TPS61010DRCR serves as the compensation node for the internal error amplifier. It must be connected to an external R-C-C network (typically 10 kΩ, 1 nF, 100 pF) to stabilize the control loop, ensure phase margin >45°, and optimize transient response. Incorrect or missing compensation can cause oscillation, poor load regulation, or startup failure - especially with high-ESR output capacitors.
Does the TPS61010DRCR provide load isolation during shutdown?
Yes - the TPS61010DRCR provides true load isolation during shutdown (EN = GND). Its proprietary synchronous rectifier control actively disconnects the PMOS body diode path between VOUT and VBAT, preventing reverse current flow and eliminating standby battery drain. This is confirmed in Section 9.3.2 of the datasheet and distinguishes it from basic boost controllers that rely on external blocking diodes.
