DA9213-DA9314-DA9215 Datasheet, PDF (1/4 Pages) Dialog Semiconductor – Multiphase DC-DC for Core and GPU rails up to 20 A

DA9213, DA9314 and DA9215
Multiphase DC-DC for Core and GPU rails up to 20 A
DA9213, DA9214 and DA9215 are DC-DC buck converter optimised for the supply
of CPUs, GPUs, and DDR memory rails in smartphones, tablets, FPGAs and other
portable applications. The fast transient response (10 A/µs) and load regulation are
optimised for the latest generation of multi core application processors.
DA9213 operates as a single four-phase buck converter delivering up to 20A output current.
DA9214 integrates two dual-phase buck converters, capable of delivering 2x 10A output
current.
DA9215 integrates a three-phase buck converter capable of delivering 15A and a single-
phase buck converter delivering 5A output current.
The output voltage is programmable 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.
To guarantee the highest accuracy and to support multiple PCB routing scenarios without
loss of performance, a remote sensing capability is implemented in DA9213, DA9214 and
DA9215.
A programmable soft start-up 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.
DA9213, DA9214 and DA9215 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 selected via GPI allows multiple instances of DA9213, DA9214
and DA9215 to be placed in the application sharing the same interface with different
addresses.
