100-V no-opto flyback regulator

Linear Technology Corporation announces the LT8303, a monolithic flyback regulator in a TSOT-23 package that significantly simplifies the design of isolated DC/DC converters. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator, LT1431, or third winding for regulation. The LT8303 operates over a 5.5-V to 100-V input voltage range, has a 0.45-A/150-V integrated DMOS power switch and delivers up to 5 W of output power, making it well suited for a wide range of telecom, datacom, automotive, industrial, medical, and military applications.
