New family of adaptable buck-boost converters delivers up to 2.5 A in a tiny footprint to shrink board space
Texas Instruments (TI) introduced a family of four high-efficiency, low-quiescent-current (IQ) 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.
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 mm2 to 25 mm2 – 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-IQ power-management portfolio, providing low 11- to 15-µA IQ 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.
