Dolphin Design provides a complete Power Management IPs platform towards 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
- Works with a smaller inductance size compared to previous product generation
- 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
