Product details
Overview
TPS613226ADBVT from Texas Instruments is a synchronous boost converter IC designed for ultra-low-power battery-powered systems. It delivers a fixed 3.6-V output with ±3% accuracy, supports 0.9–5.5-V input (including single-cell alkaline/NiMH/Li-ion), and draws only 6.5-µA quiescent current into VOUT-enabling multi-year operation in wireless sensors and portable medical devices.
For engineers reviewing the TPS613226ADBVT datasheet, TPS613226ADBVT pinout, TPS613226ADBVT application, or TPS613226ADBVT equivalent, key selection criteria include its 1.2-A peak switch current limit, SOT-23-5 package footprint, hysteretic current-mode control architecture, and compatibility with small external components (4.7-µH inductor, 22-µF ceramic output capacitor) for space-constrained designs.
Technical Context
The TPS613226ADBVT implements a hysteretic current-mode control topology that maintains constant 200-mA inductor ripple and adjusts offset based on load to sustain high efficiency under light loads. Its internal synchronous rectification eliminates external diode requirements while enabling operation down to 0.4-V input after startup.
It integrates undervoltage lockout (0.4-V threshold with 100-mV hysteresis), thermal shutdown (150°C trip, 130°C recovery), and cycle-by-cycle peak current limiting (1.2-A typical). The device operates without external compensation and supports adaptive constant-off-time mode when an external Schottky diode is added for higher output current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.6 V ±3% over –40°C to +125°C - ensures stable rail for 3.3-V logic and USB-peripheral interfaces. |
| Quiescent current | 6.5 µA into VOUT pin - enables >10-year battery life in always-on IoT endpoints powered by coin cells or alkaline batteries. |
| Peak switch current limit | 1.2 A typical - supports up to ~500 mA output at 3.6 V with 3-V input when paired with external Schottky diode. |
| Input voltage range | 0.9 V to 5.5 V - accommodates full discharge curve of 1-cell alkaline (1.5 V → 0.9 V), NiMH (1.2 V → 0.9 V), or Li-ion (4.2 V → 3.0 V). |
| Efficiency | >90% at 10-mA load (1.5-V → 2.2-V) - minimizes heat generation and extends runtime in thermally isolated enclosures. |
| Switching behavior | Hysteretic current-mode control with discontinuous conduction mode (DCM) at light loads - eliminates need for loop compensation and reduces idle power loss. |
| Thermal protection | 150°C shutdown with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
TPS613226ADBVT is housed in a 2.9-mm × 1.6-mm 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement. 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 internal connection | 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 diode anode; carries high di/dt switching current - requires short, low-inductance trace. |
| Pin 3 (NC) | No internal connection | Must be left floating or tied to GND; serves mechanical stability only. |
| Pin 4 (GND) | Power ground reference | Primary return path for switch current and IC bias; must connect to solid ground plane under device for thermal and EMI performance. |
| Pin 5 (VOUT) | Regulated output | Delivers fixed 3.6-V supply; requires local 22-µF ceramic capacitor placed within 3 mm of pin to suppress switching noise and ensure stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 6.5 µA into VOUT enables multi-year operation from CR2032 or AA alkaline cells in standby mode. |
| Hysteretic current-mode control | Eliminates external compensation network and enables seamless transition between continuous/discontinuous conduction modes for optimal light-load efficiency. |
| Integrated synchronous rectification | Reduces BOM count by removing need for external Schottky diode in standard configurations - lowers solution cost and footprint. |
| Thermal and current protection | Combines cycle-by-cycle peak current limiting (1.2 A) and junction-temperature shutdown (150°C) to prevent failure under fault conditions without external circuitry. |
| Small external component count | Requires only one inductor (4.7 µH) and one output capacitor (22 µF) for full functionality - ideal for space-constrained wearables and hearing aids. |
Applications
| Wireless Sensor Node | Portable Medical Monitor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS613222ADBVT | Fixed 5.0-V output; 1.8-A peak switch current limit; lower RDS(on) (750 mΩ HS / 150 mΩ LS). | Targets USB OTG (5-V) power delivery; supports higher output current with external Schottky diode. | Select when system requires 5-V rail and >300-mA sustained load - not drop-in compatible due to different output voltage and current capability. |

FAQ
What is the output voltage of the TPS613226ADBVT?
The TPS613226ADBVT provides a factory-trimmed fixed output voltage of 3.6 V with ±3% accuracy over –40°C to +125°C junction temperature. This value is set internally and requires no external resistors - simplifying design and improving long-term stability compared to adjustable boost converters.
Does the TPS613226ADBVT require external compensation components?
No, the TPS613226ADBVT uses a hysteretic current-mode control architecture that does not require external compensation. Its stability is inherent to the control scheme, eliminating the need for feedback capacitors or resistors - reducing BOM count and layout complexity.
Can the TPS613226ADBVT operate with input voltages below 0.9 V?
Yes - after initial startup (which requires ≥0.83 V at VOUT), the TPS613226ADBVT can continue operating with input voltage as low as 0.4 V. This extends usable battery capacity in alkaline and NiMH cells, allowing full discharge before system shutdown.
What package type is used for the TPS613226ADBVT?
The TPS613226ADBVT is supplied in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 1.6 mm. Pins 1 and 3 are no-connect (NC); Pin 2 is SW; Pin 4 is GND; Pin 5 is VOUT. The package includes an exposed thermal pad for enhanced heat dissipation.
How does the TPS613226ADBVT achieve high efficiency at light loads?
The TPS613226ADBVT achieves >90% efficiency at 10-mA load through hysteretic current-mode control, which automatically transitions into discontinuous conduction mode (DCM) under light loads. Combined with only 6.5-µA quiescent current into VOUT, this minimizes idle power loss and maximizes battery runtime.
