Description

This reference design demonstrates a validated and cost competitive power sequencing solution for an application processor or a high performance control platform. This design supports 5 different voltage rails, optimized with layout space of 12 mm × 12 mm. The design is also capable of adjusting delay time and re-configuring specific voltage level for each rail to fit different input capacitors and different processors' requirements.

Features
  • Validated power sequencing solution for application processors
  • Correct power up/down sequence, even for uncontrolled power off at various load situations
  • Power tree efficiency is maintained high both at heavy load and at a light load
  • Small layout space of power supply: area smaller than 12 mm × 12 mm
