概要

The DA9211 is a multiphase DC/DC buck converter optimized 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 optimized for the new generation of multi-core application processors.

DA9211 operates as a single four-phase buck converter delivering up to 12A of output current. The input voltage range of 2.8V to 5.5V makes it suitable for the use of single-cell Lithium-ion battery applications and 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.

Benefits

  • Dynamic voltage control (DVC)
  • Integrated power switches
  • Remote sensing at point of load
  • High efficiency over a wide output range
  • Low output ripple
  • Small <1mm height components
  • -40 ºC to +85 ºC temperature range
