Description

The programmable power management unit AS3722 features 4x DC-DC buck converters, 3x buck converter (6A to 24A) and 11 low noise LDOs. The high level of integration and the 4MHz switching frequencies ensure small system footprint.

Details

Features

  • 4 DC-DC step-down regulators (3-4MHz)
  • 3 DC-DC step-down controller with automatic phase shedding
  • 11 universal LDOs (one with DC-DC tracking feature)
  • Low power real time clock (<1uA)
  • Programmable stand-by sequence

Benefits

  • Compact design due to small coils for IO and memory voltage generation
  • High current generation with external power stages to minimize PMIC power dissipation
  • Multiple independent voltage rails for general purpose IO supplies
