Overview
Description
The DA9080 is a five-output configurable power management IC (PMIC) that has four synchronous step-down buck regulators and one 200mA LDO. One of the bucks is capable of up to 5A of output current. Robust protection features include undervoltage lockout (UVLO), overcurrent protection (OC), and thermal protection for fault protection features. The DA9080 is offered in a 32-lead QFN package.
