Dialog Semiconductor DA9211/DA9212

DA9211 & DA9212 - high current with the smallest footprint

The DA9211 and DA9212 are small size DC-DC buck converters optimized 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 optimized for the latest generation of multi-core application processors.

DA9211 is a multiphase DC-DC optimised for the supply of CPUs, GPUs, and DDR memory rails in smartphones, tablets, FPGAs and other handheld applications. The fast transient response (10A/μs) and load regulation are optimised for the new generation of multi-core application processors. DA9211 operates as a single four-phase buck converter delivering up to 12A output current. The input voltage range of 2.8 to 5.5V makes it suitable for the use of single cell Lithium-Ion battery applications as well as standard 5V supply or USB power supplies. 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.

DA9212 is a synchronous dual step down converter optimised for the supply of CPUs, GPUs, and DDR memory rails in smartphones, tablets, FPGAs and other handheld applications. DA9212 delivers two time 6 A output current suitable for the highest performing application processors such as multi core arrangements of ARM Cortex A15 family. The input voltage range of 2.8 to 5.5V makes it suitable for the use of single cell Lithium-Ion battery applications as well as standard 5V supply or USB power supplies. 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.
