Its the first block in every circuit, the power supply. Linear Technology announced the LT8301 is a monolithic flyback regulator 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 or third winding for regulation. The LT8301 operates over a 2.7V to 42V input voltage range, has a 1.2A/65V power switch and delivers up to 6 watts of output power, making it well suited for a wide variety of industrial, medical, datacom, military and automotive applications.
The LT8301 is available in TSOT-23 package with a tiny footprint. Typical operating temperature range of -40°C to 125°C, high temperature automotive grade from -40°C up to 150°C and military grade operation from -55°C to 150°C.
