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.
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
Support of 5 V input for USB or Lithium battery
Output current configuration
100 mA;200 mA;300 mA;400 mA;500 mA;1000 mA
Up to 95 % peak efficiency (for NDO configurations).
90 % efficiency down to 0.2 IMAX (for NDO configurations).
70 % efficiency down to 0.01 IMAX (for NDO configurations).
