ML4903 Datasheet (Micro Linear) - High Current Synchronous Buck Controller

ML4903, High Current Synchronous Buck Controller

The ML4903 high current synchronous buck controller provides high efficiency DC/DC conversion to generate VCCP for processors such as the Pentium® Pro and Pentium II from Intel®.

The ML4903 controller, when combined with two external MOSFETs, generates output voltages between 1.8V and 3.5V from a 12

ML4903 Features
