Renesas Electronics DA9223-A

the DA9223-A and DA9224-A. The power devices are fully integrated, so no external FETs or Schottky diodes are needed. 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.

GENERAL DESCRIPTION

DA9223-A and DA9224-A are PMICs optimized for the supply of CPUs, GPUs, and DDR memory rails in automotive in-vehicle infotainment systems, Advanced Driver Assistance Systems (ADAS), navigation and telematics applications. The fast transient response (10 A/µs) and load regulation are optimized for the latest generation of multi core application processors. DA9223-A operates as a single four-phase buck converter delivering up to 16 A output current. DA9224-A integrates two dual-phase buck converters, capable of delivering 2 x 8 A output current. Each buck regulates a programmable output voltage in the range of 0.3 V 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 V 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 both the DA9223-A and DA9224-A.
