Product Summary

The MP1542DK is a current mode step-up converter with a 2A, 0.18Ω internal switch to provide a highly efficient regulator with quick response. The MP1542DK 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 applications of the MP1542DK include LCD Displays, Portable Applications, Handheld Computers and PDAs, Digital Still and Video Cameras.
