The TPS62842EVM-103 facilitates the evaluation of the TPS62842DGR of 750-mA, step-down converter
with 60-nA I
in a DGR package. The EVM has output voltages between 1.8 V and 3.6 V from higher input
Q
voltages between 1.8 V and 6.5 V. Due to its extremely low I
lifetime for systems which have very low current consumption states such as building automation,
metering, and the Internet of Things (IoT).
