Linear Technology Corporation (Milpitas, CA) has announced the LTC3124, a dual-phase, 3MHz, current-mode, synchronous boost DC/DC converter with output disconnect and inrush current limiting. Dual-phase operation significantly reduces peak inductor and capacitor ripple currents, minimizing component size while delivering lower output ripple versus an equivalent single-phase device. Features include:

  • 5 A of switch current.
  • Output voltages as high as 15 V from an input voltage range of 1.8 V at start-up (0.5 V when running) to 5.5 V.
  • Up to 1.5 A of continuous output current at 12 V from a 5 V input.
  • An RDS(ON) of 130 mOhm (N-channel) and 200 mOhm (P-channel).
  • A VIN Range of 1.8 to 5.5 V, 500 mV After Start-Up.
