MAX20458 36V Boost Controller

Analog Devices Inc. MAX20458 36V Boost Controller is an automotive-grade PMIC that includes a 3.5A synchronous buck converter and an asynchronous boost controller with 2.1MHz and 400kHz options. The boost controller can provide power to buck converters and keep them in regulation during cold-crank operation down to 2V battery input. The IC operates with an input voltage supply from 3.5V to 36V and can work in dropout conditions by running at 95% duty cycle.
