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 5.5 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-µA quiescent current from
VOUT 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 × 2-mm VQFN package and minimum amount of external
components.
