MP3213 700KHz/1.3MHz Boost Converter with a 3.5A Switch The Future of Analog IC Technology DESCRIPTION FEATURES The MP3213 is a current mode step-up 3.5A, 0.18 , 25V Power MOSFET converter with a 3.5A, 0.18 internal switch to Uses Tiny Capacitors and Inductors provide a highly efficient regulator with fast Pin Selectable 700KHz or 1.3MHz Fixed response. The MP3213 operates at 700KHz or Switching Frequency 1.3MHz allowing for easy filtering and low noise. Programmable Soft-Start An external compensation pin gives the user Operates with Input Voltage as Low as 2.5V flexibility in setting loop dynamics, which allows and Output Voltage as High as 22V the use of small, low-ESR ceramic output 12V at 500mA from 5V Input capacitors. Soft-start results in small inrush UVLO, Thermal Shutdown current and can be programmed with an Internal Current Limit external capacitor. The MP3213 operates from Available in an 8-Pin MSOP and 10-Pin an input voltage as low as 2.5V and can QFN Package with Exposed Pad generate 12V at up to 500mA from a 5V supply. APPLICATIONS The MP3213 includes under-voltage lockout, current limiting and thermal overload protection LCD Displays to prevent damage in the event of an output Portable Applications overload. The MP3213 is available in a low Handheld Computers and PDAs profile 8-pin MSOP and 10-pin QFN package Digital Still and Video Cameras with exposed pad.
