EV2109DQ-00A
Dual 800mA, 6V, 1.2MHz Synchronous
Step-Down Converter Evaluation Board
DESCRIPTION
The EV2109DQ-00A is the evaluation board for
the MP2109. The MP2109 contains two
independent 1.2MHz constant frequency,
current mode, PWM step-down converters.
Each converter integrates a main switch and a
synchronous rectifier for high efficiency without
an external Schottky diode. The MP2109 is
ideal for powering portable equipment that runs
from a single cell Lithium-Ion (Li+) battery. Each
converter can supply 800mA of load current
from a 2.5V to 6V input voltage. The output
voltage can be regulated as low as 0.6V. It can
also run at 100% duty cycle for low dropout
applications.
