ML4901 Datasheet (Micro Linear) - High Current Synchronous Buck Controller

ML4901, High Current Synchronous Buck Controller

The ML4901 high current synchronous buck controller has been designed to provide high efficiency DC/DC conversion for next generation processors such as the Pentium® Pro from Intel®.

The ML4901 controller, when combined with 2 external MOSFETs, generates output voltages between 2.1V and 3.5V from a
