ABSTRACT:
A 384X-based burst mode PWM controller includes an oscillator to generate a pulse signal of a constant frequency, an output circuit to generate an output signal based on the pulse signal, an error amplifier to generate an amplified error signal, a logic control current source connecting to a current sense input of a comparator, the comparator which compares the voltage of the current sense input with the voltage of the error signal to generate a comparison signal, a PWM latch to generate a pulse control signal corresponding to the pulse signal and based on the comparison signal. The pulse control signal controls the output circuit and the logic control current source in opposite conditions of turning on and off. The controller can replace 384X directly and save energy.
