Product details
Overview
TPS613222ADBVR from Texas Instruments is a synchronous boost converter optimized for ultra-low-power battery-powered systems, delivering fixed 5-V output at up to 1.8-A switch current with only 6.5-µA quiescent current into VOUT and ±3% output voltage accuracy over temperature. It operates from 0.9-V to 5.5-V input and supports high-efficiency conversion (≥90% at 10-mA load, 1.5-V to 2.2-V), making it ideal for single-cell alkaline/NiMH or Li-ion portable electronics.
For engineers reviewing the TPS613222ADBVR datasheet, TPS613222ADBVR pinout, TPS613222ADBVR application, or TPS613222ADBVR equivalent, key selection criteria include its 5-V fixed output, 1.8-A peak switch current limit, SOT-23-5 (DBV) package, hysteretic current-mode control architecture, and thermal shutdown protection - all critical for compact, long-life power management in space-constrained devices.
Technical Context
The TPS613222ADBVR implements a hysteretic current-mode control topology that maintains constant 200-mA typical inductor ripple while dynamically adjusting switching frequency to sustain regulation across light-to-moderate loads. Its internal error amplifier regulates output by modulating the offset of this ripple based on feedback from the fixed 5-V output divider.
This device integrates both high-side and low-side synchronous MOSFETs (RDS(on) = 750 mΩ / 150 mΩ), supports operation down to 0.4-V input post-startup, and includes undervoltage lockout (UVLO) with 0.4-V threshold and 100-mV hysteresis, plus thermal shutdown at 150°C with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±3% over –40°C to +125°C - ensures stable USB-compatible rail without external resistors. |
| Peak Switch Current Limit | 1.8 A typical - enables ≥500-mA output current at 3-V-to-5-V conversion when used with external Schottky diode. |
| Quiescent Current | 6.5 µA into VOUT pin - minimizes battery drain in always-on or standby modes of portable equipment. |
| Input Voltage Range | 0.9 V to 5.5 V - supports single-cell alkaline (0.9–1.6 V), NiMH (0.9–1.4 V), and Li-ion (3.0–4.2 V) sources. |
| Efficiency | ≥90% at 10-mA load, 1.5-VIN → 2.2-VOUT - extends runtime in low-power wireless peripherals and sensors. |
| Switching Control | Hysteretic current-mode - eliminates need for external compensation, simplifies design, and improves transient response. |
| Thermal Protection | 150°C shutdown with 20°C hysteresis - prevents damage during sustained overload or poor PCB thermal design. |
Pinout & Package
TPS613222ADBVR is housed in a 2.9-mm × 1.6-mm 5-pin SOT-23 (DBV) package with exposed pad for thermal performance. Pin 1 is NC (no connection), Pin 2 is SW (switch node), Pin 3 is NC, Pin 4 is GND, and Pin 5 is VOUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (NC) | No connection | Internally unconnected - must be left floating or tied to GND per layout best practice; no electrical function. |
| Pin 2 (SW) | Power switch node | Connects to inductor and external Schottky anode - carries high di/dt switching current; requires tight layout and ground plane coupling. |
| Pin 3 (NC) | No connection | Internally unconnected - same handling as Pin 1; avoid routing signals or traces to this terminal. |
| Pin 4 (GND) | Power ground | Main return path for switch and output currents - must connect directly to low-impedance PCB ground plane under device. |
| Pin 5 (VOUT) | Regulated output | Delivers fixed 5-V supply - requires local 22-µF ceramic capacitor placed within 3 mm of pin for stability and noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 6.5 µA into VOUT pin - enables >1-year shelf life in coin-cell or alkaline-powered IoT sensors. |
| Synchronous rectification | Integrated high-side (750 mΩ) and low-side (150 mΩ) MOSFETs - eliminates external diode loss, improving efficiency by ~8% vs. asynchronous designs. |
| Fixed 5-V output | Factory-trimmed ±3% accuracy - removes need for feedback resistor network, reducing BOM count and layout area. |
| External Schottky support | Enables ≥500-mA output at 3-V-to-5-V - meets USB OTG and HDMI auxiliary power requirements without redesigning core circuitry. |
| Hysteretic current-mode control | No external compensation required - reduces design cycle time and eliminates instability risks from capacitor ESR variations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS613222ADBV | Same silicon, identical electrical specs, but in tape-and-reel packaging (DBV) vs. cut-tape (ADBVR) - no functional difference. | Identical use cases; differs only in packaging format and reel quantity. | Select ADBVR for prototyping or low-volume builds; DBV for automated SMT production. |
| TPS61291DRVR | Lower 3.5-µA IQ, 1.2-A switch limit, 3.3-V fixed output - lacks 5-V option and external Schottky support. | Better for ultra-low-power 3.3-V systems (e.g., BLE sensors); unsuitable for 5-V USB OTG or high-current loads. | Choose only if 3.3-V output suffices and <3.5-µA IQ is mandatory; not a drop-in replacement for 5-V or >500-mA needs. |
Compared with TPS613222ADBVR, TPS613222ADBV offers identical performance in reel format for volume manufacturing, while TPS61291DRVR trades 5-V capability and higher current for lower quiescent current - making it viable only where output voltage and load requirements align.

FAQ
What is the output voltage of the TPS613222ADBVR?
The TPS613222ADBVR provides a factory-trimmed fixed 5.0-V output with ±3% accuracy over temperature (–40°C to +125°C). This eliminates the need for external feedback resistors and ensures compatibility with USB-powered peripherals and 5-V logic interfaces without additional regulation stages.
Does the TPS613222ADBVR support external Schottky diodes?
Yes, the TPS613222ADBVR supports an external Schottky diode connected from SW to VOUT to increase output current capability. With this configuration, it delivers >500 mA at 3-V input to 5-V output - enabling use in USB OTG and HDMI auxiliary power applications where higher load currents are required.
What package type is used for the TPS613222ADBVR?
The TPS613222ADBVR uses a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 1.6 mm with an exposed thermal pad. Pins 1 and 3 are no-connect (NC), Pin 2 is SW, Pin 4 is GND, and Pin 5 is VOUT - requiring careful PCB layout to minimize parasitic inductance on SW and ensure effective thermal dissipation.
What is the minimum input voltage for startup of the TPS613222ADBVR?
The TPS613222ADBVR starts up when the input voltage reaches a typical 0.87 V at the VOUT pin (with RLOAD ≥ 250 Ω). After startup, it continues operating down to 0.4 V input - allowing full utilization of single-cell alkaline or NiMH batteries through deep discharge, extending usable battery life significantly.
How does the TPS613222ADBVR achieve high efficiency at light loads?
The TPS613222ADBVR achieves ≥90% efficiency at 10-mA load via hysteretic current-mode control, which enables discontinuous conduction mode (DCM) under light loads. Combined with only 6.5-µA quiescent current into VOUT and synchronous rectification (150 mΩ low-side RDS(on)), it minimizes switching and conduction losses across the entire load range.
