The Future of Analog IC Technology
DESCRIPTION
The EV2111/12DQ-00A is an evaluation board
for the MP2112DQ.
The MP2112 is a 1MHz constant frequency,
current mode, PWM step-down converter. The
device integrates a main switch and a
synchronous rectifier for high efficiency without
an external Schottky diode. It is ideal for
powering portable equipment that runs from a
single cell Lithium-Ion (Li+) battery. The
MP2112 can supply 1A of load current from a
2.5V to 6V input voltage. The output voltage
can be regulated as low as 0.6V. The MP2112
can also run at 100% duty cycle for low dropout
applications.
The MP2112 is available in a space-saving
6-pin 3mmx3mm QFN package with an
exposed pad.
