TPS6307x Buck-Boost Converters

Texas Instruments offers its TPS6307x, 2 V to 16 V, buck-boost converters with 3.6 A switch current

Image of Texas Instruments' TPS63070 and TPS630701 Buck-Boost ConvertersTexas Instruments' TPS6307x is a high efficiency, low quiescent current, buck-boost converter suitable for applications where the input voltage can be higher or lower than the output voltage. Output currents can go as high as 2 A in boost mode and in buck mode. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. At low load currents, the converter enters power save mode to maintain high efficiency over a wide load current range. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery. The device is available in a 2.5 mm × 3 mm QFN package.
