The EV1542DK-SEPIC-00A is the demo board for sepic applications using the MP1542, a current mode step up converter with a 2A, 0.18Ω 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, whichallows the use of small, low ESR ceramic output capacitors. The soft-start results in smallinrush 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.
