The LP8752x-Q1 is a high-efficiency, high-performance power supply device with four step-down DC/DC converter cores for automotive applications. Table 1 lists the output characteristics of the regulators.
NOTE
Maximum output current is given as the maximum capability per rail. For each device the total combined output current must not exceed 10 A.

The LP8752x-Q1 also supports switching clock synchronization to an external clock. The nominal frequency of the external clock can be from 1 MHz to 24 MHz with 1-MHz steps.
Additional features include:
Three enable signals can be multiplexed to general purpose I/O (GPIO) signals. The direction and output type (open-drain or push-pull) are programmable for the GPIOs.
