MP1542
700KHz/1.3MHz Boost Converter
with a 2A Switch
The Future of Analog IC Technology FEATURES DESCRIPTION
The MP1542 is a current mode step up
converter with a 2A, 0.18Ω 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. •
