Texas Instruments TPS61299/TPS61299-Q1 5.5V Boost Converters

Texas Instruments TPS61299/TPS61299-Q1 5.5V Boost Converters are synchronous boost converters with a 95nA ultra-low quiescent current and average input current limit. These converters provide a power solution for portable equipment with an alkaline and coin cell battery. The TPS61299/TPS61299-Q1 converters deliver high efficiency under light-load conditions to achieve long operation times. The TPS61299-Q1 converters are AEC-Q100 qualified for automotive applications. These converters are used in smart watches, smart bands, and portable medical equipment.

The TPS61299/TPS61299-Q1 has a wide input voltage range from 0.5V to 5.5V and an output voltage range from 1.8V to 5.5V. The device has different versions for the average input current limit from 5mA to 1.9A. These converters with a 1.2A current limit can support up to 500mA output current from 3V to 5V conversion and achieve approximately 94% efficiency at 200mA load. TPS61299/TPS61299-Q1 converters are available in a 6-ball 1.2mm x 0.8mm WCSP package and a 6-pin 1.6mm x 0.6mm SOT563 package.
