GENERAL DESCRIPTION
DA9213, DA9214, and 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. Each buck regulates a programmable output voltage in the range 0.3 to 1.57 V. 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. 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.
