ML4900- High Current Synchronous Buck Controller
GENERAL DESCRIPTION
The ML4900 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 ML4900 controller, when bined with two N-channel MOSFETs, generates output voltages between 2.1V and 3.5V from a 5V 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 ML4900 can be enabled/disabled via the SHDN pin. While disabled, the output of the regulator is pletely isolated from the circuit’s input supply. The ML4900...
