Abstract
A current multiplier/divider-configured, feed-forward compensation circuit for a pulse width modulator (PWM) controller for a buck-mode DC-DC converter is operative to achieve constant loop gain irrespective of the magnitude of the input voltage, obviates the need for parameter calculations/adjustments of circuit components to conform with the PWM frequency selected by the user, and is effectively immune to variations in temperature and manufacturing process.
