EV2101DQ-00A
1.6MHz, 800mA Synchronous
Step-Down Converter plus 200mA LDO
EVALUATION BOARD
DESCRIPTION
The EV2101DQ-00A is the evaluation board for
the MP2101 step-down converter. It is designed
for high efficiency, step-down applications.
The MP2101 is a 1.6MHz current mode
synchronous buck converter plus LDO, which
provides two regulated output rails. Both control
loops are internally compensated, and all power
devices are integrated. Channel 1 is a
synchronous buck providing up to 92% efficiency
and 800mA output current from a 2.5V to 6V
input voltage. Channel 2 is an LDO that can
supply up to 200mA of load current from either
the power input or the output of channel 1 to
minimize the overall power loss and output
noises.
The MP2101 is available in a space-saving
3mm x 3mm QFN10 package with an exposed
pad.
