ML4902 Datasheet (Micro Linear) - High Current Synchronous Buck Controller

ML4902, High Current Synchronous Buck Controller

The ML4902 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 ML4902 controller, when combined with 2 N-channel MOSFETs, generates output voltages between 1.8V and 3.5V from a 5V

ML4902 Features
