A control scheme is presented in which both edges of the PWM signal are modulated. The PWM signal is latched to prevent multiple transitions. The sawtooth ramp is replaced by a triangular wave derived from a digital clock, which is particularly suitable for high frequency operation. Additionally, the two sided PWM halves the response time.
