概览

DA9217 is a SubPMIC suitable for supplying CPUs, GPUs, DDR memory rails in smartphones, tablets, RF modules and other handheld applications.

DA9217 operates as a single-channel dual-phase buck converter, each phase requiring a small external 0.10 μH inductor. 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 low voltage systems, including, but not limited to, all Li-Ion battery supplied applications.

DA9217 Block Diagram
DA9217 Block Diagram
  • 2.5 V to 5.5 V input voltage
  • 0.3 V to 1.9 V output voltage
  • 4 MHz nominal switching frequency
  • ±1 % accuracy (static)
  • ±5 % accuracy (dynamic)
  • I2C-compatible interface (FM+)
  • Configurable GPIOs
  • Programmable soft-start
  • Voltage, current, and temperature supervision
  • -40 °C to +85 ºC ambient temperature range
  • Input voltage range provides flexibility to run from single cell Li-Ion battery or standard 3.3V or 5V system rail  
  • Differential voltage sensing provides tight regulation accuracy requirements of CPU cores in mobile SoCs 
  • 4MHz switching frequency reduces footprint & height of output inductor and minimizes output capacitance, lowering BOM cost
  • Triggered through either an I2C or GPIO interface, output dynamic voltage control can be used to optimize system power consumption
