MAX20053AAUD+T General Description

The MAX20050–MAX20053 are high-brightness LED (HBLED) drivers for automotive exterior lighting applications.Consisting of a fully synchronous step-down converterwith integrated MOSFETs, the devices are capable ofdriving a series string of LEDs at up to 2A, with a minimumnumber of external components. The MAX20050/MAX20052 utilize internal loop compensation to minimizecomponent count, while the MAX20051/MAX20053/MAX20053D useexternal compensation for full flexibility.
