A 3 MHz, 48W Boost converter with high speed and high accuracy Peak Current Control Unit (PCCU) is presented. The Boost controller IC adopts a novel PCCU consisting of a fully differential open-loop operational transconductance amplifier (OTA) and a trans-impedance amplifier (TIA), which can minimize the delay and error of the whole control loop. In the PCCU, the compensated output of error amplifier...
