ML4901CT中文资料High Current Synchronous Buck Controller数据手册Micro Linear规格书

描述 Description

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
