    摘要: A load driving circuit comprises a converting circuit, a converting controller, a load driving modulator, and a charge spike protection circuit. The converting circuit is adapted to be coupled to an output power source and supplies a driving power source to drive a load. The converting circuit has an output capacitance coupled to an output end thereof. The converting controller controls an amount of the driving power source responsive to a current or a voltage of the load. The load driving modulator and the load, connected in series, are coupled to the output end and so the load driving modulator adjusts an electronic state of the load. The charge spike protection circuit is coupled to the output capacitance and at least one connecting node of the load and the load driving modulator to provide a unidirectional charge release path to the output capacitance.

    摘要: An LED driving circuit comprises a converting circuit, a current regulator, a converting controller and a low dimming protection blocking circuit, is disclosed. The converting circuit is adapted to perform a power conversion to provide a driving voltage for lighting an LED module. The current regulator is coupled to the LED module for regulating a current flowing through the LED module. The current regulator conducts and stops conducting the current flowing through the LED module according to a dimming signal, and executes a protection process when the LED module operates abnormal. The converting controller controls the power conversion of the converting circuit according to a voltage level of at least one connection node of the current regulator and the LED module. The low dimming protection blocking circuit stops the protection process of the current regulator when the driving voltage is lower than a predetermined value.
