Product Description

The MP1542 is a current mode step up converter with a 2A, 0.18O 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.

Kit details

The EV1542DK-00A is the evaluation board for the MP1542, a current mode step-up converter with a 2A, 0.18Ω internal switch to provide a highly efficient regulator with quick response. The MP1542 can be operated at 700KHz or 1.3MHzallowing 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. Soft-start results in smallinrush 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 a low profile 8-pin MSOP package.
