Text: AND8138/D DC-DC Converter for Driving High-Intensity Light-Emitting Diodes with the SEPIC , , what's needed is a nonisolated dc-dc converter that can handle an input that is below or above the output. The single-ended primary inductor converter ( SEPIC ) meets this requirement. It has an inductor , an example SEPIC , designed for 5.0 V output and 10 V input. IC1 ID1 C1 D1 L1 C2 U1 , A 2A 1.5 A 4A 3A Figure 1. Example of a SEPIC ID1 The function of the SEPIC is as follows
