The LT8303 monolithic flyback regulator in a TSOT-23 package claims to simplify isolated dc/dc converter design. The device samples the isolated output voltage directly from the primary-side flyback waveform, eliminating the need for an opto-isolator or third winding for regulation. The LT8303 operates over a 5.5V to 100V input voltage range, has a 0.45A/150V integrated DMOS power switch, and delivers up to 5W of output power, making it suitable for a wide range of telecom, datacom, automotive, industrial, medical and military applications. Additional features include output short-circuit protection, a 70-µA no load operating quiescent current, internal loop compensation, accurate enable, and under-voltage lockout with hysteresis. Extended and industrial versions operate over a junction temperature range of -40°C to +125°C. Pricing starts at $3.15 each/1.000. For more information, visit http://www.linear.com/product/LT8303
