DA9080

A highly integrated PMIC with 4 Bucks, 1 LDO & 8 bit ADC in a QFN package

DA9080 block diagram

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