MAX25239AFFA/VY+, Switching Voltage Regulators HV 3.2A buck boost converter in P90

MAX25239 series automotive 2V to 36V, 6A Buck-Boost converter is small, synchronous with integrated H-bridge switches. These ICs provide 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. This IC has typical 8.2A and 10A input current limit options and can support continuous load currents up to 6A depending on the input-to-output voltage ratio and operating frequency. It has 40°C to 125°C grade 1 automotive temperature range. It feature a power-OK (POK) indicator, undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, and thermal shutdown. Typical applications are ADAS ECU, infotainment systems, body electronics, start-stop systems, point-of-load power supplies.
