Abstract
A system and a method for controlling a DC-DC converter include a microcomputer for deriving an input limiting current value by dividing an input limiting power value by an input voltage value. A conversion circuit scales the input limiting current value to a limiting voltage value. A voltage control circuit derives a control voltage value based on an output voltage value and a reference voltage value and defines the limiting voltage value as a control voltage limiting value. A current control circuit generates a pulse width modulation (PWM) control signal based on the control voltage value.
