Latest Patents

Xu Guang Zhang holds a patent for a 384X-based burst mode PWM controller. This controller includes an oscillator that generates a pulse signal of a constant frequency. It features an output circuit that produces an output signal based on the pulse signal. Additionally, an error amplifier generates an amplified error signal. A logic control current source connects to a current sense input of a comparator, which compares the voltage of the current sense input with the voltage of the error signal to generate a comparison signal. The PWM latch then generates a pulse control signal corresponding to the pulse signal and based on the comparison signal. This pulse control signal effectively manages the output circuit and the logic control current source in opposite conditions of turning on and off. The controller is designed to directly replace the 384X and save energy.
