RC5054A Product details

Description
The RC5054A 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  RC5054A integrates all of the control, output adjustment,  monitoring and protection functions into a single package.

Features
• Drives Two N-Channel MOSFETs
• Operates from +5V Power Input
• Simple Single-Loop Control Design
    - Voltage-Mode PWM Control
• Fast Transient Response
    - High-Bandwidth Error Amplifier
    - Full 0% to 100% Duty Ratio
• Excellent Output Voltage Regulation
• TTL Compatible 5 Bit Digital-to-Analog Output Voltage  Selection - Wide Range - 1.3VDC to 3.5VDC
    - 0.1V Binary Steps from 2.1VDC to 3.5VDC
    - 0.05V Binary Steps from 1.3VDC to 2.1VDC
• Power-Good Output Voltage Monitor
• Over-Voltage and Over-Current Fault Monitors
    - Does Not Require Extra Current Sensing Element, Uses  MOSFET’s RDS(ON)
• Small Converter Size
    - Constant Frequency Operation
    - 200kHz Free-Running Oscillator Programmable from  50kHz to 1MHz

Applications
• Power Supply for Pentium®, Pentium Pro, PowerPC™  and Alpha™ Microprocessors
• High-Power 5V to 3.xV DC-DC Regulators
• Low-Voltage Distributed Power Supplies
