Content for TPS61022
The TPS61022 provides a power supply solution for portable equipment and IoT devices powered by various batteries and super capacitors. The TPS61022 has minimum 6.5-A valley switch current limit over full temperature range. With a wide input voltage range of 0.5 V to 55 V, the TPS61022 supports supercapacitor backup power applications, which may deeply discharge the supercapacitor. The TPS61022 operates at 1-MHz switching frequency when the input voltage is above 1.5 V. the switching frequency decreases gradually to 0.6 MHz when the input voltage is below 1.5 V down to 1 V. A MODE pin sets the TPS61022 operating either in power-save mode or forced PWM mode in light load condition. The TPS61022 only consumes a 26-pA quiescent current from Vgyr in light load condition. During shutdown, the load is completely disconnected from the input power. The TPS61022 has 5.7-V output overvoltage protection, output short-circuit protection, and thermal shutdown protection. The TPS61022 offers a very small solution size with its 2-mm x 2-mm VQFN package and minimum amount of external components.
