Product Summary

The HIP6004BCB-T is a Buck and Synchronous-Rectifier (PWM) Controller and Output Voltage Monitor. The HIP6004BCB-T provides complete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck topology. The HIP6004B integrates all of the control, output adjustment, monitoring and protection functions into a single package. The applications of the HIP6004BCB-T include Power Supply for Pentium Pentium Pro, Pentium II, PowerPC, K6, 6X86, and Alpha, Microprocessors, High-Power 5V to 3.xV DC-DC Regulators, Low-Voltage Distributed Power Supplies.
