Operating over an 18V to 560V input voltage range, the LT8315 high-voltage monolithic flyback regulator promises to simplify the design of an isolated dc/dc converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator for regulation. It has a 0.3A/630V integrated power switch and delivers up to 15W of output power. Several off-the-shelf transformers identified in the data sheet can be used for numerous applications. Additional features include output short-circuit protection, 70-µA no load operating quiescent current, accurate enable and under-voltage lockout with hysteresis, and output diode temperature compensation. The LT8315 is available in a TSSOP-20 package with four pins removed for high voltage spacing. Extended and industrial versions operate over a junction temperature range of -40°C to +125°C. A high temperature automotive grade operates from -40°C to +150°C. Pricing starts at $4.15 each/1,000. For more info and a datasheet, visit http://www.linear.com/product/LT8315
