DC-DC Converters Suit DDR2-DDR3 Memory Termination Supply Applications

摘要

Enpirion introduced the first two members of a family of PowerSoC DC-DC converters for DDR2/ DDR3 VTT applications: the 8 A EV1380 and the 4 A EV1340. These low-power switch-mode converters are complete power systems on a chip (PowerSoC),rnachieving up to 94 percent efficiency and integrating the inductor, power switches, gate drive, controller, and loop compensation. EV13xx PowerSoC product features include desirable power density, integrated inductor technology, exceptional noise and ripple performance exceeding VTT requirements, and they meet DDR2/DDR3 tracking requirements.
