摘要： A power loss protection integrated circuit includes a VIN terminal, a VOUT terminal, an STR terminal, a switch circuit (eFuse), a control circuit, and a prebiasing circuit. In a normal mode, current flows from a power source, into VIN, through the eFuse, out of VOUT, and to the output node. A switching converter of which the control circuit is a part is disabled. If a switch over condition then occurs, the eFuse is turned off and the switching converter starts operating. The switching converter receives energy from STR and drives the output node. Switch over is facilitated by prebiasing. Prior to switch over, the prebiasing circuit prebiases a control loop node as a function of eFuse current flow prior to switch over. When the switching converter begins operating, the node is already prebiased for the proper amount of current to be supplied by the switching converter onto the output node.

摘要： A static energy regulator for lighting in the form of a device that is inserted between the feed and the load has a converter, connected to the load and to a controller, so that the intensity signal through it follows the form of an indication signal. Another converter, connected to the feed and to another controller, supplies an intensity signal that follows the form of another recognition signal proportional to the voltage of a condenser connected between the two converters. Thus it is possible to control the energy flux, to keep consumption at the desired value, compensate for variations of the power supply, reduce costs and lengthen the life of the load. The regulator can be applied to any charge whether or not it is linear and regardless of power factor. In application thereof to lighting it permits the reduction of the luminous flux thus overcoming the inadequacies of previous systems and effectively controlling the characteristics of the energy supplied.
