TI Launches TPS63900 DC/DC Buck-Boost Converter
Standby current level of 75nA, support for various RF standards


Smart grid applications connect to networks via multiple RF standards. Developers must ensure sufficient output current for these applications to connect to the network while simultaneously reducing standby current.

Accordingly, Texas Instruments (TI) released the TPS63900 DC/DC buck-boost converter on the 2nd.

The TPS63900 has a low standby current of approximately 75 nA and features 32 user-programmable output voltage settings (ranging from 1.8 to 5 V). Additionally, dynamic voltage scaling allows the output voltage to be switched while the application is running.

With a wide supply voltage range (1.8 to 5 V) and programmable input current limit (1 to 100 mA or unlimited), the TPS63900 is suitable for use with a variety of primary and secondary batteries, including 3S alkaline, 1S Li-MnO2, and 1S Li-SOCl2.

Additionally, the high output current capability supports commonly used RF standards such as sub-GHz, BLE, LoRa, wM-Bus, and NB-IoT.

Suitable for water and gas meters that must operate continuously while consuming a lot of power when sharing data, the TPS63900 is available in a 2.5×2.5mm WSON package.

Pricing starts at $0.80 for quantities of 1,000. Evaluation modules are available for $49 on TI.com, with various payment and shipping options available.
