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®.

FEATURES
■ Designed to meet Pentium Pro and Pentium II VRM power supply requirements
■ DC regulation to +1% maximum
■ Proprietary circuitry provides transient response of ±5% maximum over a 0A to 20A load range
■ Programmable output voltage (1.8V to 3.5V) is set by an onboard 2 chord 4-bit DAC
■ Synchronous N-channel buck topology for maximum power conversion efficiency
■ Fixed frequency operation for easier system integration
■ Integrated anti-shootthrough logic, short circuit protection, shutdown, and UV lockout
