DA9068

System PMIC for Multi-Core Application Processors

A team of engineers is ready to answer your questions

Powerful DC-DC converter system featuring 33 regulators

DA9068 is a power management unit (PMU) optimized for supplying systems with multi-core CPUs, I/O, DDR memory, and peripherals.

The PMIC features dual-phase, single-phase, and RF buck converters. High efficiency is achieved over a wide load range. All power switches are integrated and a high switching frequency allows low-profile inductors to be used.

DA9068 also includes additional modules such as real time clock (RTC), general purpose 12-bit ADC (GPADC) and general purpose I/O pins (GPIO). These support different functions such as battery voltage supervision and device over-temperature protection. All DA9068 features can be accessed by software via the host processor, allowing high flexibility of applications.

Controlled by a programmable digital power manager, the user-programmable switched/linear regulators may be configured to meet the start-up sequence, voltage, and timing requirements for most applications. Dynamic Voltage Scaling (DVS) is available to achieve optimal processor energy-per-task performance. Dialog’s patented SmartMirror™ dynamic biasing is implemented on all linear regulators.

Dynamic voltage control (DVC) allows supply voltages of DA9068 to be controlled dynamically according to the operating point of the system. The control can be realized via direct register writes through the I2C interface or via GPIOs.
