MP1542  
700KHz/1.3MHz Boost Converter  
with a 2A Switch  
The Future of Analog IC Technology  
FEATURES  
DESCRIPTION  
2A, 0.18, 25V Power MOSFET  
Uses Tiny Capacitors and Inductors  
Pin Selectable 700kHz or 1.3MHz Fixed  
Switching Frequency  
The MP1542 is a current mode step up  
converter with a 2A, 0.18internal 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.  
Programmable Soft-Start  
Operates with Input Voltage as Low as 2.5V  
and Output Voltage as High as 22V  
12V at 500mA from 5V Input  
UVLO, Thermal Shutdown  
Internal Current Limit  
Available in 8-Pin MSOP Packages  
APPLICATIONS  
LCD Displays  
Portable Applications  
Handheld Computers and PDAs  
Digital Still and Video Cameras  
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.
