10.5-W Nonsynchronous SEPIC Reference Design With Non-coupled Inductors

Description

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 6.0 V to 28 V. The output voltage is 21.0 V with a maximum load current of 0.5 A. The design has compact form factor and low cost.

Features

  • Nonsynchronous SEPIC design with non-coupled inductors
  • Wide input voltage range from 6 V to 28 V
  • Compact form factor and low-cost design

Applications

  • Traction inverter-low voltage
