GENERAL DESCRIPTION
DA9213, DA9214, and DA9215 are PMUs optimized for the supply of CPUs, GPUs, and DDR memory rails in smartphones, tablets and other portable applications. DA9213 operates as a single four-phase buck converter delivering up to 20 A output current. DA9214 integrates two dual-phase buck converters, capable of delivering 2 x10 A output current. DA9215 integrates a three-phase buck converter capable of delivering 15 A and a single-phase buck converter delivering 5 A output current. With an external resistor divider the output voltage can be set to any voltage between 1.57 V and 4.3 V The input voltage range of 2.8 to 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. The power devices are fully integrated, so no external FETs or Schottky diodes are needed.
