MIC23153YMT EV: 0.62 ~ 3.6V @ 2A, 2.7 ~ 5.5V in
Summary
This board enables the evaluation of the MIC23153, a fully integrated 2A, 4 MHz switching regulator featuring HyperLight Load ™ mode, Power Good output indictor, and programmable soft start. The MIC23153 is highly efficient throughout the entire output current range, drawing just 23 µA of quiescent current in operation.
The tiny 2.5 mm x 2.5 mm thin MLF® package, in combination with the 4 MHz switching frequency, enables a compact sub-1 mm height solution with only four external components. The MIC23153 provides accurate output voltage regulation under the most demanding conditions and responds extremely quickly to a load transient with exceptionally small output voltage ripple.
This board needs a single 10 W bench power source adjustable from 2.7 V to 5.5 V. The loads can either be active (electronic load) or passive (resistor) with the capability to dissipate 7 W.
It is ideal to have an oscilloscope to view the circuit waveforms, but not essential. For the simplest tests, two voltage meters are required to measure input and output voltage. For efficiency measurements, two voltage meters and two ammeters are requiredto prevent errors due to measurement inaccuracies.
There is no reverse input protection on this board. Be cautious when connecting the input source to ensure correct polarity is observed.
