MAX25240AFFF/VY+

MAX25240 is an automotive small, synchronous, buckboost converter with integrated H-bridge switched. This IC provides a fixed-output regulation voltage and an externally adjustable output voltage in the 3V to 20V range with an input voltage above, below, or equal to the output regulation voltage. It as a wide input voltage range of 2V to 36V. The MAX25240 has 200KHz switching frequency which offers better efficiency and relieves the power consumption concern. The SYNC input allows three operation modes: skip mode with ultra-low quiescent current, forced fixed-frequency PWM operation and synchronization to an external clock. The IC also includes spreadspectrum frequency modulation to minimize EMI interference. Typical applications include ADAS ECU, infotainment systems, body electronics, start-stop systems, point-of-load power supplies.
