DA9213

DA9213, DA9214, and DA9215 Multi-Phase 5A/Phase DC-DC Buck Converter 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. The fast transient response (10 A/µs) and load regulation are optimized for the latest generation of multi core application processors. 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 a...
