N2 - In this paper, an adaptive slope compensation circuit is proposed that can be applied for the current-controlled DC-DC converter. In order to maintain stability, the negative-slope compensation should be used for this converter with duty ratio higher than 0.5. Fixed value of this slope results in the limited operating range. The proposed adaptive slope compensation is designed that can be suitable for wide range of input and output voltages and incorporated into the DC-DC boost converter for LED driver applications. Operations are verified through measurement results of circuit implementation in a 0.35-um BCD technology.
