Richtek offers complete Vcore power solution for Intel and AMD CPUs, and ever award Intel reference design several times. Richtek’s Vcore solution are featured high accuracy up to ± 0.5%, SVID supporting, CCM/DEM for energy saving, and support no load offset function for system over-clocking. Our modulation technology (G-NAVP) comes from our experience in analog controllers used in PC.

Richtek Vcore products have been extensively verified in customer designs, with easy design, high reliability, high power density, low total BOM cost, fast load transient response, precise current balance under all load conditions, and excellent stability. We also provide smart design tool and GUI which can reduce design effort and shorten design cycle.
