Block Diagram of system power IC for portable devices (5)

Functions

Power IC with a 3-ch step-down DCDC converter for Li-Ion batteries implemented in a super-thin wafer level CSP. (µPD68846, general-purpose products, evaluation boards available)


Features

  • Synchronous commutation step-down 3-ch DCDC converter
    (3.3 V/500 mA, 1.8 V/500 mA, 1.2 V/500 mA)
  • High-efficiency
    • 95% (@Vo = 3.3 V, Io = 300 mA)
    • 92% (@Vo = 1.8 V, Io = 150 mA)
  • Built-in power transistor, external shot key not needed
  • Extra-small package (3.6 mm×3.6 mm, 36-pin WL-CSP)

Set

Ideal for use as an engine power supply for portable devices.
