GENERAL DESCRIPTION
The EV1542DK-SEPIC-00A is the demo board
for sepic applications using the MP1542, a
current mode step up converter with a 2A,
0.18
internal switch to provide a highly
efficient regulator with fast response. The
EV1542DK-SEPIC-00A 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. The soft-start
results in small inrush current and can be
programmed with an external capacitor. The
EV1542DK-SEPIC-00A can operate from a
single Li-Ion battery to generate 3.3V at up to
500mA.
Other features include under voltage lockout,
current limiting and thermal overload protection,
all available in a low profile 8-pin MSOP
package.
