Very Low Input Voltage 2-Phase Synchronous Step-Down Controller with Step-Up Converter

Features


  • 2-phase synchronous step-down controller
    • 2-phase synchronous continuous conduction mode for high-efficiency step-down converters
    • Out-of-phase operation for low input current ripples
    • Operates up to 1 MHz per channel
    • Configurable dual outputs or 2-phase single-output operation with peak current-mode control
    • Excellent current sharing between phases
    • Wide input voltage range: 1.8 V to 15 V
    • Duty cycle up to 90%
    • 0.5 V feedback voltages for low-voltage outputs
    • Precision 50 mV current-limit threshold
    • Patented Combi-Sense™ technique for high SNR of current-sensing
    • Individual soft-start, overload shutdown and enable
  • Step-up regulator
    • Wide input voltage range: 1.8 V to 15 V
    • Operates at twice the individual channel frequency of the buck controllers
    • 0.3 V VCESAT switch at 1 A
    • Fixed frequency with current-mode control
