Abstract
A frequency programmable feed forward oscillator and triangular wave generator is disclosed having a first input for receiving an input voltage and a second input for receiving an input current. Circuitry within the device responsive to the input voltage scales the amplitude of a triangle wave form according to the provided input voltage and provides the scaled output voltage at a first output. In conjunction, the circuitry also generates a scaled PWM frequency responsive to the provided input current and provides this at a second output.
