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.
