Abstract

In values article were investigated the capabilities of the optimization of the conditions of the microcircuit pulse width modulation (PWM) the controller of output stage HV9910 with the aim of the improvement of its exiting performance. The option of the conditions of fitting controller with the maintenance of the constant value of the discharging time of power inductor . Allowed to carry out the regulation of exiting load current in the changeover of incoming supply voltage. In adition the analysis of the time intervals of the operation of inductor showed the capabilities of the optimization of the option of the size of it inductance L with the aim of the decline of the effect of its technological scatter on.

The led measurements of the value of the colored  temperature of the strip of jointed concurrently _ sequentially emitting diodes depending on connected  to them power showed that this value practically unvarying in all band connected power. This allowed to apply the behavior of the analog control (dimming) of luminous flux which delete extraneous modulation of values luminous flux being present in application pulse width modulation (PWM) dimming. Thus, as a result led research it was concluded about the capability of the application of microcircuit HV9910 in the output stage of LED driver with the support of adoptable operating performance in the minimal value of product.
