Overview
April 1997 PRELIMINARY ML4901 High Current Synchronous Buck Controller GENERAL DESCRIPTION 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 12V supply.
The output voltage is selected via an internal 4-bit DAC.
Output currents in excess of 14A can be attained at efficiencies greater than 90%.
The ML4901 can be enabled/disabled via the SHDN pin.
While disabled, the output of the regulator is completely isolated from the circuit’s input supply.
