1. General description
DA9211 and DA9212 are PMUs optimised for the supply of CPUs, GPUs, and DDR memory rails in
smartphones, tablets and other handheld applications. The fast transient response (10A/µs) and load
regulation are optimised for the new generation of multi-core application processors.
DA9212 integrates two dual-phase buck converters, each phase using a small external 0.47 µH
inductor. Each buck is capable of delivering up to 6 A output current at an output voltage in the range
0.3 - 1.57 V. The input voltage range of 2.8 5.5 V makes it suited for a wide variety of low voltage
systems, including all Li-Ion battery-powered applications.
DA9211 operates as a single four-phase buck converter delivering up to 12 A output current. To
guarantee the highest accuracy and to support multiple PCB routing scenarios without loss of
performance, a remote sensing capability is implemented in both DA9211 and DA9212.
The power devices are fully integrated, so no external FETs or Schottky diodes are needed.
A programmable soft start-up can be enabled, which limits the inrush current from the input node and
secures a slope-controlled activation of the rail.
The Dynamic Voltage Control (DVC) supports adaptive adjustment of the supply voltage depending
on the processor load, either via direct register writes through the communication interface (I2C or
SPI compatible) or via an input pin.
A voltage tracking functionality is implemented allowing the buck output voltage to be controlled by
an analogue input signal. This feature, together with a digital clock input, allows complete control of
the buck converter from external signals in the platform.
DA9211 and DA9212 feature integrated over-temperature and over-current protection for increased
system reliability without the need for external sensing components. The safety feature set is
completed by a VDDIO under voltage lockout.
The configurable I2C address selection via GPI allows multiple instances of DA9211 and DA9212 or
both to be placed in the application sharing the same communication interface with different
addresses.
