General Description

The MAX16922 power-management integrated circuit (PMIC) is designed for medium-power-level automotive applications, and integrates multiple supplies in a small footprint. The device includes one high-voltage stepdown converter (OUT1) and three low-voltage cascaded DC-DC converters (OUT2, OUT3, OUT4). OUT1 and OUT2 are step-down DC-DC converters, and OUT3/OUT4 are linear regulators. The device also includes a reset output (RESET) and a high-voltage-compatible enable input (EN).
