LTC1628CG-SYNC#PBF DatasheetThe LTC® 1628-SYNC is a high performance dual step down switching regulator controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows phase lockable frequency of up to 300kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages out of phase.
