GENERAL DESCRIPTION
The EV1542DK-00A is the evaluation board for
the MP1542, a current mode step-up converter
with a 2A, 0.18⦠internal switch to provide a
highly efficient regulator with quick 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 a low
profile 8-pin MSOP package.
