Analog Devices / Maxim Integrated MAX25239 Automotive Buck-Boost Converters

Analog Devices MAX25239 Automotive Buck-Boost Converters feature integrated H-bridge switches and a fixed-output regulation voltage. The converters also have an externally adjustable output voltage in the 3V to 20V range. The ICs feature an input voltage above, below, or equal to the output regulation voltage. These Analog Devices devices have 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. The converters also have a wide input voltage range of 2V to 36V.
