Renesas Electronics DA9217
DA9217 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. It is capable of delivering up to 6 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 lowvoltage systems, including, but not limited to, all Li-Ion battery supplied applications.

GENERAL DESCRIPTION
DA9217 operates as a single-channel dual-phase buck converter, each phase requiring a small external 0.10 µH inductor. With remote sensing, the DA9217 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 (I2Ccompatible) or with a programmable input pin. A configurable GPI allows multiple I2C address selection for multiple instances of DA9217 in the same application. DA9217 has integrated over-temperature and over-current protection for increased system reliability, without the need for external sensing components.
