TI TPS613226ADBVT 1.8A Synchronous Boost Converter With 6.5µA Quiescent Current

Shenzhen Mingjiada Electronics Co., Ltd, as a global leading authorised distributor of electronic components, specialises in supplying TI's TPS613226ADBVT synchronous boost converter, which, with its ultra-low quiescent current of only 6.5µA and high output current capability of 1.8A, has become the ideal power supply solution for portable electronic devices, Internet of Things (IoT) terminals and medical equipment.

Product Description Of TPS613226ADBVT
TPS613226ADBVT is a synchronous boost converter with only 6.5-µA quiescent current. The TPS613226ADBVT provides a power-supply solution for products powered by alkaline battery, NiMH rechargeable battery, or one-cell Li-ion battery. The boost converter is based on a hysteretic control topology using synchronous rectification to obtain maximum efficiency at minimal quiescent current. The TPS613226ADBVT also allows the use of small external inductor and capacitors. Higher than 90% efficiency is achieved at 10-mA load from 1.5-V input to 2.2-V output conversion.

TPS613226ADBVT can also support high output current applications with an external schottky diode. The TPS613226ADBVT provides higher than 500-mA output current capability at 3-V input voltage to 5-V output voltage conversion with an external Schottky diode in parallel with the internal rectifier FET.

The output voltage is set internally to a fixed output voltage from 1.8 V to 5.5 V in increments of 0.1 V. Thus, it only needs two external components to get the desired output voltage. The TPS613226ADBVT also implements thermal shutdown protection function.

Core Features Of TPS613226ADBVT
Ultra-low quiescent current: With an operating quiescent current of only 6.5µA, the TPS613226ADBVT significantly extends the life of battery-powered devices, making it particularly suitable for applications requiring long standby times.
High output current capability: The TPS613226ADBVT supports switching currents up to 1.8A, which can provide stable power output for various types of loads and meet the needs of high-performance portable devices.
Wide Input Voltage Range: 0.7V to 5.5V input voltage range makes it compatible with a wide range of battery types, including single-cell alkaline/nickel-metal hydride batteries, lithium-ion batteries, and more.
High Efficiency Synchronous Rectification: The TPS613226ADBVT integrates synchronous rectification technology with a maximum efficiency of up to 95%, which effectively reduces energy loss and improves the overall energy efficiency of the system.
Adjustable Output Voltage: The output voltage can be flexibly adjusted within the range of 1.8V to 5.5V through external resistors, adapting to the voltage requirements of different application scenarios.
Small package: SOT23-6 (DBV) small package, the size of only 2.9mm × 1.6mm, very suitable for space-constrained portable equipment design.
Rich Protection Functions: TPS613226ADBVT has built-in protection mechanisms such as over-current protection, over-temperature protection, and under-voltage lockout (UVLO) to ensure the safe operation of the system under various abnormal conditions.

Application Of TPS613226ADBVT
Portable electronic devices
The TPS613226ADBVT can effectively extend battery life in consumer electronics such as smartphones, tablets, and TWS headphones. Its ultra-low quiescent current characteristics are particularly suited to the standby mode of these devices, while its 1.8A output current capability meets the high power requirements of devices in active states.

IoT Terminal Devices
For all types of IoT sensor nodes, smart home devices and wearables, the TPS613226ADBVT provides an ideal power solution. These devices typically need to be in a low-power state for long periods of time, waking up only intermittently for data transmission, and the 6.5µA quiescent current can significantly reduce overall system power consumption and extend battery replacement cycles.

Medical Electronics
In applications such as portable medical monitoring equipment and hearing aids, the TPS613226ADBVT not only provides a stable power output, but its low noise characteristics also prevent power disturbances from affecting sensitive medical signals. The small package helps to realise miniaturised designs for medical devices.

Industrial Sensors and Instrumentation
Wireless sensor networks, data acquisition terminals and other devices in industrial environments often require unattended operation for long periods of time, and the ultra-low quiescent current feature of the TPS613226ADBVT ensures that these devices remain operational for long periods of time in extreme environments.
