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 power save mode can be disabled, forcing the converter to operate at a fixed switching frequency. The maximum average current in the switches is limited to a typical value of 4A. The output voltage is programmable using an external resistor divider or is fixed internally on the chip. The converter can be disabled to minimize battery drain. During shutdown, the load is disconnected from the battery. \u003cul\u003e \u003cli\u003eUp to 96% efficiency\u003c\/li\u003e \u003cli\u003e3A Output current at 3.3V in step down mode (VIN = 3.6 to 5.5V)\u003c\/li\u003e \u003cli\u003eMore than 2A output current at 3.3V in boost mode (VIN \u0026gt;2.5V)\u003c\/li\u003e \u003cli\u003eAutomatic transition between step down and boost mode\u003c\/li\u003e \u003cli\u003eDynamic input current limit\u003c\/li\u003e \u003cli\u003eLess than 50µA device quiescent current\u003c\/li\u003e \u003cli\u003ePower save mode for improved efficiency at low output power\u003c\/li\u003e \u003cli\u003eForced fixed frequency operation at 2.4MHz and synchronization possible\u003c\/li\u003e \u003cli\u003eSmart power good output\u003c\/li\u003e \u003cli\u003eLoad disconnect during shutdown\u003c\/li\u003e \u003cli\u003eOver-temperature protection\u003c\/li\u003e \u003cli\u003eOvervoltage protection\u003c\/li\u003e \u003cli\u003eGreen product and no Sb\/Br\u003c\/li\u003e \u003c\/ul\u003e Applications \u003cp\u003e Power Management, Communications \u0026amp; Networking, Portable Devices, Multimedia, Imaging, Video \u0026amp; Vision, Medical, Industrial, Metering, LED Lighting \u003c\/p\u003e Warnings This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.\u003ch4\u003eOther details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTEXAS INSTRUMENTS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e TPS63021DSJR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eEach (Supplied on Cut Tape)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Change Notice EN\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"https:\/\/www.farnell.com\/datasheets\/2916056.pdf\" target=\"_blank\" title=\"Download data sheet Texas Instruments TPS63021DSJR \u0026lt;b\u0026gt;TPS63021DSJR\u0026lt;\/b\u0026gt; DC\/DC Switching Buck-Boost Regulator Fixed 1.8V to 5.5V in 3.3V\/4A out VSON-14\" download\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/files\/file_4379f50c-e237-48f9-beae-a4e625c5b304_icon.png?9736775303194905289\" alt=\"Download technical document - datasheet - Tanotis India\" width=\"25\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"color: #999999;\"\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
