TPS5904A Overview
The TPS5904 and TPS5904A optoisolated feedback amplifiers consist of the industry standard TL1431 precision programmable reference and an optocoupler. Reference-voltage tolerance for the TPS5904 is 0.8%, and for the TPS5904A, 0.4%. The devices are primarily intended for use as the error-amplifier/reference/ isolation-amplifier element in isolated ac-to-dc power supplies and dc/dc converters.
