TPS61022RWUR

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
