Overview

This reference design showcases a nonsynchronous single-ended primary-inductor converter (SEPIC) with non-coupled inductors using the LM51561-Q1 device. The design covers an input voltage range of 6.0V to 28V. The output voltage is 21.0V with a maximum load current of 0.5A. The design has compact form factor and low cost.

Features
  • Nonsynchronous SEPIC design with non-coupled inductors
  • Wide input voltage range from 6V to 28V
