MAX20030 Overview
The MAX20030/MAX20031 ICs are automotive 2.2MHz dual-synchronous step-down controllers with preboost controller and low-IQ LDO. The preboost controller enables VOUT1 and VOUT2 to stay in regulation during coldcrank operation all the way down to a battery input of 2V. The ICs offer two high-voltage synchronous step-down controllers that operate 180 degrees out of phase.
