Abstract
This work presents a new control circuit that uses a voltage-to-time converter to realize high switching frequency DC-DC converters. The proposed solution is adopted in a 20-MHz DC-DC buck converter. Simulation results demonstrate the effectiveness of the approach showing very fast load and line-regulation transient responses (around 1.5 mus) when using a 250-nH inductor and a 10-muF output capacitor. The simulated peak power efficiency is 90%.
