  • Minimum Input Voltage: 3 V (4.5 V for Start-Up).
  • Output Voltage up to 100 V.
  • Bypass (VOUT = VIN) Operation.
  • 1.2-V Reference with ±1% Accuracy.
  • Free-Run and Synchronizable Switching to 1 MHz.
  • Peak-Current-Mode Control.
  • Robust 3-A Integrated Gate Drivers.
  • Adaptive Dead-Time Control.
  • Optional Diode-Emulation Mode.
  • Programmable Cycle-by-Cycle Current Limit.
  • Hiccu.
