1 / 62 page  DA9220 High-Performance Dual-Channel DC-DC Converter Datasheet Revision 2.1 17-Sep-2020 CFR0011-120-00 1 of 62 © 2020 Dialog Semiconductor General Description DA9220 is a power management unit (PMU) suitable for supplying CPUs, GPUs, DDR memory rails in single in-line pin package (SIPP) modules, smartphones, tablets, and other handheld applications. DA9220 integrates two single-phase buck converters, each phase requiring a small external 0.10 µH inductor. Each buck is capable of delivering up to 3 A output current at a 0.3 V to 1.9 V output voltage range. The 2.5 V to 5.5 V input voltage range is suitable for a wide variety of low-voltage systems, including, but not limited to, all Li-Ion battery supplied applications. With remote sensing, the DA9220 guarantees the highest accuracy and supports multiple PCB routing scenarios without loss of performance. The pass 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 rail activation. The dynamic voltage control (DVC) supports adaptive adjustment of the supply voltage dependent on the processor load, via either a direct register write using the communication interface (I2C- compatible) or with a programmable input pin. A configurable GPI allows multiple I2C address selection for multiple instances of DA9220 in the same application. DA9220 has integrated over-temperature and over-current protection for increased system reliability, without the need for external sensing components.
