Designed to power AMD’s new 64-bit Hammer CPUs, the LTC3719 is a two-phase, synchronous step-down switching regulator employing the company’s PolyPhase technique. This technique ensures precision current sharing, which reduces thermal stress, facilitates thermal management, and eliminates the need for heatsinks. It also minimizes the requirement for input and output capacitors. The LTC3719 has a 5-bit programmable voltage identification (VID) code corresponding to the core voltage range of AMD’s Hammer CPUs: 0.8V to 1.55V. Core current range is from 15A to 40A. The device’s power can be delivered with 95% efficiency from an input voltage ranging from 4.5V to 36V. Pricing starts at $4.35 each/1,000.
