摘要： A pulse width modulator includes an amplifier module, a comparator module, and a filter module. The amplifier module receives a feedback voltage signal from a passive network, and generates first and second non-inverted voltage signals and first and second inverted voltage signals in response to the feedback voltage signal. The comparator module receives the first and second non-inverted voltage signals and the first and second inverted voltage signals, and provides first and second differential voltage signals corresponding to the first and second non-inverted voltage signals and the first and second inverted voltage signals. The filter module is coupled between the amplifier module and the comparator module, and is operable so as to attenuate high frequency components of the first and second non-inverted voltage signals. As such, the presence of noise in the feedback voltage signal does not affect differential operation of the comparator module.

摘要： A circuit protection device includes an overheat protecting circuit connected to a main circuit and capable of being activated so as to shut down the main circuit when operating temperature of the main circuit reaches a predetermined value, and a current limiting circuit connected to the main circuit for preventing current through the main circuit from exceeding a predetermined threshold value. The current limiting circuit is further connected to the overheat protecting circuit and controls activation of the overheat protecting circuit when the current through the main circuit reaches the predetermined threshold value. Therefore, erroneous operation of the circuit protection device due to a shift in component characteristics of the overheat protecting circuit attributed to limitations in fabrication can be avoided.
