DA9223-A and DA9224-A Auto Grade 0.8 mm Pitch Multi-Phase Buck Converter 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.
