High-efficiency hyper-speed control buck regulators

Mouser now stocks Micrel's MIC49x0 hyper-speed control buck regulators. The devices offer high-efficiency, synchronous regulation with ultra-fast transient response. The regulators are suitable for supplying processor core and I/O voltages from a 5V or 3.3V bus in for applications such as DTVs, set-top boxes, printers, DVD players and distributed power supplies. The MIC49x0 provides a switching frequency up to 3.3MHz while delivering peak efficiencies up to 95% and is designed to use a small inductor and output ceramic capacitor without the need for external ripple injection.
