DESCRIPTION
The EV2104 evaluation board is designed for
low dropout step down converter applications. It
implements the MP2104 1.7MHz Fixed
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 equipments that runs from a
single cell Lithium-Ion (Li+) Battery. It can
supply 600mA of load current from a 2.5V to 6V
input voltage. The output voltage can be
regulated as low as 0.6V. In 100% Duty Cycle
Dropout operation, it works with minimum input
voltage as low as output voltage.
