MP2104
1.7MHz, 600mA Synchronous
Step-Down Converter
The Future of Analog IC Technology
TM
DESCRIPTION
The MP2104 is a 1.7MHz 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 MP2104 can supply
600mA of load current from a 2.5V to 6V input
voltage. The output voltage for the MP2104DJ
can be regulated as low as 0.6V, while the output
voltages
of
the
MP2104DJ-1.5
and
MP2104DJ-1.8 are fixed at 1.5V and 1.8V,
respectively. The MP2104 can also run at 100%
duty cycle for low dropout applications.
The MP2104 is available in a low profile (1mm)
5-pin, TSOT package.
