The Future of Analog IC Technology
DESCRIPTION
The MP2104 is a 1.7MHz constant frequency,
current mode, PWM step-down converter. The
device
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
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 low profile (1mm)
5-pin TSOT and 0.75mm TQFN-6 packages.
