RC5054 - Programmable Synchronous DC-DC Converter Controller for Low Voltage Microprocessors

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.

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-Go.
