MPQ1542 Industrial Grade, 700KHz/1.3MHz Boost Converter with a 2A Switch

Product Detail

The MPQ1542 is a current-mode, step-up converter with a 2A, 0.18O internal switch that provides a highly efficient regulator with fast response. The MPQ1542 can be operated at 700kHz or 1.3MHz, allowing for easy filtering and low noise. An external compensation pin provides flexibility in setting loop dynamics, which allows the use of small, low ESR, ceramic output capacitors. Soft start results in a small inrush current and can be programmed with an external capacitor. The MPQ1542 operates from an input voltage as low as 2.5V and can generate 12V at up to 500mA from a 5V supply. Full protection features include under-voltage lockout (UVLO), current limiting, and thermal overload protection, which prevents damage in the event of an output overload. The MPQ1542 is available in a low profile, 8-pin, MSOP package.
