New family of adaptable buck-boost converters delivers up to 2.5 A in a tiny footprint to shrink board space

DALLAS, Sept. 30, 2019 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today introduced a family of four high-efficiency, low-quiescent-current (I(Q)) buck-boost converters that feature tiny packaging with minimal external components for a small solution size. The integrated TPS63802, TPS63805, TPS63806 and TPS63810 DC/DC noninverting buck-boost converters offer wide input and output voltage ranges that scale to support multiple battery-driven applications, helping engineers simplify and accelerate their designs. For more information, samples and evaluation modules, see

Each of the devices in the family automatically selects buck, buck-boost or boost mode according to the operating conditions. Their complete solution size of 19.5 mm(2) to 25 mm(2) - up to 25% smaller than similar devices - is a result of compact packaging, an advanced control topology requiring few external multilayer ceramic capacitors, and tiny 0.47-µH inductors. The devices offer a wide 1.3-V to 5.5-V input and 1.8-V to 5.2-V output voltage range, which helps engineers speed their designs and encourages reuse across multiple applications.

These DC/DC converters are the latest addition to TI's industry-leading low-I(Q) power-management portfolio, providing low 11- to 15-µA I(Q) for excellent light-load efficiency while minimizing power losses and extending run times in battery-driven applications such as portable electronic point-of-sale terminals, grid infrastructure metering devices, wireless sensors and handheld electronic devices.

Key features and benefits

    --  The TPS63802 is a 2-A buck-boost converter with low 11-µA I(Q)
        consumption suitable for pulsed-load applications such as industrial
        Internet of Things devices.
    --  The TPS63805 is a 2-A buck-boost converter with a 22-µF output
        capacitor and 0.47-µH inductor resulting in a small solution size of
        19.5 mm(2) that meets the requirements of handheld industrial and
        personal electronics applications.
    --  The TPS63806 is a 2.5-A buck-boost converter with a focus on improved
        load-step regulation for applications with an aggressive load profile
        that require tight regulation, such as time-of-flight sensors in
        smartphones, cameras or augmented reality devices.
    --  The TPS63810 is a 2.5-A buck-boost converter with I(2)C interface for
        dynamic voltage scaling through either a two-wire interface or the VSEL
        pin, enabling the device to serve as a pre-regulator or voltage envelope
        tracker for systems found in smartphones, wireless hearing aids or
