An Inductor Emulator Approach to Peak Current-mode Control in a 4-Phase Buck Regulator


Abstract High-efficiency DC-DC converters make up one of the important blocks of state-of-the-art power supplies. The trend toward high level of transistor integration has caused load current demands to grow significantly. Supplying high output current and minimizing output current ripple has been a driving force behind the evolution of Multi-phase topologies. Ability to supply large output current with improved efficiency, reduction in the size of filter components, improved transient response make multi-phase topologies a preferred choice for low voltage-high current applications.

Current sensing capability inside a system is much sought after for applications which include Peak-current mode control, Current limiting, Overload protection. Current... (more)
