MAX20049DATEE/VY+ General Description

The MAX20049 is a dual step-down converter IC with twolow-dropout regulators (LDOs), providing a single-chipsolution for automotive cameras. The two step-down convertersare designed for fixed-frequency PWM operationwith input voltages from 5V to 17V for MAX20049, 4V to17V for MAX20049C, and 3.5V to 17V for MAX20049D. The dedicated high-voltage inputs allow for a flexible solution.
