DESCRIPTION
The MP1542 is a current mode step up
converter with a 2A, 0.18 internal switch to
provide a highly efficient regulator with fast
response. The MP1542 can be operated at
700KHz or 1.3MHz allowing for easy filtering
and low noise. An external compensation pin
gives the user flexibility in setting loop
dynamics, which allows the use of small, low-
ESR ceramic output capacitors. Soft-start
results in small inrush current and can be
programmed with an external capacitor. The
MP1542 operates from an input voltage as low
as 2.5V and can generate 12V at up to 500mA
from a 5V supply.
The MP1542 includes under-voltage lockout,
current limiting and thermal overload protection
preventing damage in the event of an output
overload. The MP1542 is available in low profile
8-pin MSOP packages.
