Aiming at the low voltage, high current and low voltage ripple demand of 100G DSP, this paper presents a power design using LTM4650 as the core device. Analyzing the causes and influencing factors of voltage ripple, a solution that used multi-phase parallel and the low ESR capacitor was applied, to suppress the voltage ripple. The results of LTspice simulation software and the actual circuit test, proved that the power design can meet the power requirements of 100G DSP and is able to guarantee the stability of the DSP system.
