Abstract

This paper presents designing of a low power LED driver circuit, Single Inductor Buck-Boost Application with Analog Dimming and Low Frequency PWM Dimming and PWM LED boost application. The operation principles and design considerations of the studied LED driver and buck-boost application can be analyzed in LT spice software. The current mode PWM (pulse width modulation) controlled boost converter for power LEDs application is introduced. Besides, the current mode PWM controller is used to ensure the system is stable. In all the circuits the input range is 9v to 26v and the output is boosted accordingly. The calculations are based on design specifications.
