Abstract

This paper presents the system analysis of the continuous-conduction mode (CCM) dual-loop controlled light-emitting-diode (LED) boost driver. In order to predict the system performance, including loop gain, line regulation and load regulation, the equivalent circuit models of the LED boost drivers are constructed to derive the system transfer functions. Based on the given circuit specifications and parameters, the calculated results are compared with the SIMPLIS* simulations and measured results to verify the derived transfer functions.
