May 1998 ML4902 High Current Synchronous Buck Controller GENERAL DESCRIPTION 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 supply. The output voltage is selected via an internal 2 chord 4-bit DAC. In the upper range, the output can be set between 2.1V and 3.5V in 100mV steps. In the lower range, the output can be set between 1.8V and 2.05V in 50mV steps. Output currents in excess of 20A can be attained at efficiencies greater than 90%. The ML4902 can be enabled/disabled via the SHDN pin.
