Abstract
A control voltage is generated as a function of on-time and off-time of a main regulator loop in response to apparent duty cycle of a voltage regulator circuit. Such control voltage is used in a circuit as to yield a virtual constant frequency of operation. No external compensation is required. This reduces external connections while maintaining stable, accurate, constant frequency operation of a switching voltage regulator circuit.
