DC/DC Step-Down Converter has PLL and output tracking.(Dual PolyPhase DC/DC Step-Down Controller with PLL & Output Tracking)

Utilizing dual, 180* output of phase controllers, LTC3828 step-down synchronous switching controller features integrated tracking for sequencing multiple voltage rails and PolyPhase[R] operation. It converts 4.5-28 V input voltage to 2 regulated output voltages, adjustable from 0.8 V up to 99% of input voltage. Operating at 3, 4, or 6 phases, IC has constant 550 kHz frequency current mode architecture and can also be locked to 260-550 kHz clock to reduce EMI.
