Overview

  • Operates from 3.3V to 5V Input
  • 0.8V to VIN Output Range - 0.8V Internal Reference - ±1.5% Over Load, Line Voltage and Temperature
  • Drives N-Channel MOSFETs
  • Simple Single-Loop Control Design - Voltage-Mode PWM Control
  • Fast Transient Response - High-Bandwidth Error Amplifier - Full 0% to 100% Duty Cycle
  • Lossless, Programmable Overcurrent Protection - Uses Upper MOSFET’s rDS(on)
  • Converter can Source and Sink Current
  • Small Converter Size - Internal Fixed Frequency Oscillator - ISL6439: 300kHz - ISL6439A: 600kHz
  • Internal Soft-Start
  • 14 Pin SOIC or 16 Lead 5x5 QFN
