Linear Technology's 5A, 15V 2-phase synchronous boost regulator

July 9, 2014

 Linear Technology Corp. announces 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.
