Dolphin Design offer a Reusable Power Kit Library toward three objectives: To standardize and ease Power Regulation Network integration To enable diverse optimizations To reduce Time-to-Market The eSR-Tugela is an inductor-based buck switching regulator with high efficiency.

Key Benefits

  • High efficiency buck regulator (up to 95% peak), over wide load current range
  • Pulse With Modulation (PWM) mode enabling to master the frequency response
  • Automatic mode change of the Power Stage Unit, maintaining high-efficiency at low load current
  • 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
