Description

eSR-Niagara-Bu-dm-ref-[1.9-4.4]-[0.8-3.3]-Ixx.01, like any Power Management Virtual Component designed by Dolphin Design, is readily retargetable toward any submicron CMOS process.

Features
  • High efficiency buck regulator (up to 95% in peak), thanks to dual mode (dm) controller
  • Pulse Frequency Modulation (PFM) mode at low load and Pulse With Modulation (PWM) mode at high load.
  • Low Bill-Of-Material: fully integrated feedback and active compensation loop do not require additional external passive components.
  • Behavioral models: ease integration in SoC and optimized Power Management Network (PMNet) by verifying mode transitions as well as noise propagation
