Texas Instruments today introduced a new bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60nA, which is one third of the IQ of similar competing boost converters. The TPS61094 buck/boost converter integrates a buck super capacitor charger and a boost DC-DC converter, while providing ultra-low quiescent current. The TPS61094 solution with super capacitor and the current hybrid layer capacitor (HLC) Compared with the program, the program can help engineers extend battery life by up to 20%. The powerful discharge capability of supercapacitors helps support relatively large peak loads, which is very important for battery-powered industrial applications such as smart meters, smoke detectors and video doorbells, and medical applications that require long standby.
Nowadays, designs based on lithium thionyl chloride (Li/SOCl?) batteries usually require a parallel connection of an expensive HLC to support the management of relatively large peak loads, but this is not the most cost-effective solution. TPS61094 has both 60nA ultra-low quiescent current and integrated supercapacitor charge and discharge management circuit, allowing engineers to use supercapacitors instead of HLC to support large peak loads, and will be used in applications that use disposable battery power and need to run continuously for more than 10 years. The battery life is extended by up to 20%. Similarly, TPS61094 can provide a backup power management solution during a safe power outage or power outage period. In addition to extending battery life, TI’s ultra-low power buck/boost converter TPS61094 has a 2A inductor current limit capability in boost mode. Therefore, the output current of TPS61094 is twice that of competing boost converters. The powerful output current capability enables TPS61094 to support wider input voltage and more types of wireless transceiver modules, such as Narrowband Internet of Things (NB-IoT), LTE-M, Wi-SUN?, MIOTY, Bluetooth? and wireless M- Bus. For example, TPS61094 can support a continuous output current exceeding 250mA and an input voltage as low as 0.7V. Simplify the system design and save up to 50% of peripheral circuits. Typical industrial applications such as smart meters require multiple circuit components to implement backup power management and support large current load functions. After integrating a buck charger and a boost converter in a single chip, discrete buck chargers, inductors, and two external capacitors can be eliminated, which can reduce the number of components by 50% and maximize board space . Packaging, availability TPS61094 is now available through TI and authorized distributors, the device adopts 2.0mm x 3.0mm, 12-pin WSON package. Minimum packaging and non-standard quantities of tape and reel are available on TI.com.cn and other channels. TI.com.cn also provides TPS61094EVM-066 evaluation board
