LT3804 secondary side dc/dc regulator includes an integrated optocoupler driver for dual output isolated power supplies. Single controller solution is housed in a small 28-lead TSSOP package and designed for converting 36- 72 V supplies to output voltages of 5, 3.3, 2.5, 1.8, and 1.5 V and even lower at up to 50 W per output. Differential Kelvin voltage sensing is used for each output feedback to achieve high regulation accuracy and design simplicity. Applications include 48-V distributed power, datacom/telecom, DSL/cable modems, servers, and RAID systems. as well as industrial and automotive instruments.
