560V Input, No-Opto Isolated Flyback Converter Design Note 559

摘要

The LT8315operatesata wide inputvoltage range of 18V to 560V, delivering up to 15W of isolated output power. It requires no opto-coupler, and includes rich features such as low ripple Burst Mode® operation, soft-start, programmable current limit, undervoltage lockout, temperature compensation, and low quiescent current. The high level of integration simplifies the design of low component count, high efficiency solutions in a wide variety of applications: from battery powered systems to automotive, industrial, medical, telecommunications power supplies and isolated auxiliary/ housekeeping power supplies.
