MP2012
The Future of Analog IC Technology
Low Voltage, 2.7-6V Input,1.5A, 1.2MHz
Synchronous Step-Down Converter
DESCRIPTION
The MP2012 is a fu lly integrated, internally
compensated 1.2MHz fixed frequency PWM
step-down converter. It is idea l f or powering
portable eq uipment that runs from a single cell
Lithium-Ion (Li+) Battery, with an input range
from 2.7V to 6V. The MP2012 can provide up to
1.5A of load current wit h output voltage as low
as 0.8V. It can also operate at 100% duty cycle
for low drop out applications. With p eak current
mode control and internal compensation, the
MP2012 is stable with ceramic cap acitors and
small indu ctors. Fault conditio n protection
includes cy cle-by-cycle current limiting and
thermal shutdown.
MP2012 is available in a small QFN6 (3x3 mm)
package.
