General Description

DA9080 is a five-channel advanced, configurable, system power management IC (PMIC) with four

buck regulators and one LDO. This highly integrated, flexible PMIC is capable of up to 10 A of output

current. The output voltage of the regulators can be programmed and sequenced based on the

application needs. The DA9080 also integrates an 8-bit ADC, along with several other features, that

simplifies overall system design. Dynamic voltage control (DVC), robust protection features, and a

dedicated I2C interface that supports multiple modes extend the applicability of this device to a wide

range of end applications.

The high-efficiency, fast transient response, and small footprint of the DA9080 lends itself to become

the preferred power solution for a host of complex, high-performance applications. The DA9080 is

offered in a QFN package.
