Texas instruments introduces family of four high-efficiency, low-quiescent-current (iq) buck-boost converters

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 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. key features and benefits: the tps63802 is a 2-a buck-boost converter with low 11-Μa iq 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 mm2 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 i2c 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 headphones.
