It delivers up to 400 mA output current from a 2.5V to 6V input voltage range. With a 2.25 MHz fixed switching frequency, it allows the use of small inductors and capacitors, minimizing solution size. The device integrates low RDS(on) switches, achieving up to 95% efficiency. It features automatic PFM\/PWM mode transition for light-load efficiency, output voltage accuracy of ±1.5%, and a typical quiescent current of 15 µA. The TPS62221DDCT is available in a thin SOT-23 package, making it ideal for space-constrained designs.\u003c\/p\u003e\u003ch2\u003eDetailed Technical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e2.5V to 6V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003eAdjustable (0.7V to VIN) or fixed options\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e400 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitching Frequency\u003c\/td\u003e\n\u003ctd\u003e2.25 MHz (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficiency\u003c\/td\u003e\n\u003ctd\u003eUp to 95%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuiescent Current\u003c\/td\u003e\n\u003ctd\u003e15 µA (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Accuracy\u003c\/td\u003e\n\u003ctd\u003e±1.5%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003eSOT-23-THIN (DDCT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHigh efficiency: up to 95%\u003c\/li\u003e\n\u003cli\u003e2.25 MHz fixed switching frequency for small external components\u003c\/li\u003e\n\u003cli\u003eAutomatic PFM\/PWM mode transition for light-load efficiency\u003c\/li\u003e\n\u003cli\u003eLow quiescent current: 15 µA\u003c\/li\u003e\n\u003cli\u003eOutput voltage accuracy: ±1.5%\u003c\/li\u003e\n\u003cli\u003eIntegrated synchronous rectifier\u003c\/li\u003e\n\u003cli\u003eShort-circuit and thermal protection\u003c\/li\u003e\n\u003cli\u003eAvailable in thin SOT-23 package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTarget Applications\u003c\/h2\u003e\u003cp\u003eThe TPS62221DDCT is ideal for battery-powered portable devices, such as smartphones, tablets, and wearables.
