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®.

FEATURES
■ Designed to meet Pentium®Pro power supply requirements
■ DC regulation to +1% maximum
■ Proprietary circuitry provides transient response of +5% maximum over 300mA to 14A load range
■ Programmable output voltage (2.1V to 3.5V) is set by an onboard 4-bit DAC
■ Synchronous buck topology for maximum power conversion efficiency
■ Fixed frequency operation for easier system integration
■ Integrated antishoot-through logic, short circuit protection, and UV lockout
■ Shutdown control provides load isolation
