Abstract
A variable frequency modulator including a compensation network, first and second pulse control networks and a linearity controller. The compensation network is configured to provide a compensation signal indicative of an output load condition. The first pulse control network is configured to initiate pulses on a pulse control signal and to adjust operating frequency based on changes of the compensation signal. The second pulse control network is configured to terminate the pulses on the pulse control signal based on a predetermined timing parameter. The linearity controller is configured to adjust timing of terminating the pulses based on a predetermined steady state operating frequency and an actual operating frequency to maintain modulator gain at a constant level.
