DESCRIPTION
The MP9115 is a fully integrated, internally
compensated 1.2MHz fixed frequency PWM
step-down converter. It is ideal for powering
portable equipment that runs from a single cell
Lithium-Ion (Li+) Battery, with an input range
from 2.7V to 6V. The MP9115 can provide up to
2.5A of load current with output voltage as low
as 0.8V. It can also operate at 100% duty cycle
for low dropout applications.
With peak current mode control and internal
compensation, the MP9115 is stable with
ceramic capacitors and small inductors. Fault
condition protection includes cycle-by-cycle
current limiting and thermal shutdown.
MP9115 is available in the small 10-pin
3mmx3mm TQFN package.
