1 / 63 page  DA9213, DA9214, and DA9215 Multi-Phase 5A/Phase DC-DC Buck Converter Datasheet Revision 3.4 10-Feb-2022 CFR0011-120-00 1 of 62 © 2022 Renesas Electronics 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 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. 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. DA9213, DA9214, and DA9215 feature integrated over-temperature and over-current protection for increased system reliability without the need for external sensing components. The safety feature set is completed by a VDDIO under-voltage lockout. The configurable I2C address selection via GPI allows multiple instances of DA9213, DA9214, and DA9215 or both to be placed in the application sharing the same communication interface with different addresses.
