Abstract: PURPOSE: To provide a PWM control circuit for operating current mode control in a complete digital mode without necessitating the usage of any error amplifier, or excessively complicating the circuit. CONSTITUTION: This circuit includes first and second comparators COMP 1 and 2 for a sense resistance RSENSE, and a bi-directional stable logic circuit FFD 2 driven by the output of the second comparator COMP 2, which can generate a logical signal supplied to the third input of a bi-directional stable logic circuit FFD 1 for prohibiting the usage of a power switch Ml only in a preliminarily set time.
