Description

The TPS5904 and TPS5904A optoisolated feedback amplifiers consist of a precision programmable reference

and an optocoupler. Reference-voltage tolerance for the TPS5904 is 0.8%, and for the TPS5904A is 0.5%.

These 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. The optocoupler is a gallium-arsenide (GaAs)

light-emitting diode that emits at a wavelength of 940 nm, combined with a silicon phototransistor. The current

transfer ratio (CTR) ranges from 100% to 400% in the standard version. The TPS5904A version with a

150%-to-300% CTR is available for higher-performance applications. When using the TPS5904 or TPS5904A,

power supply designers can reduce component count and save space in tightly packaged designs. The

tight-tolerance reference eliminates the need for adjustments in many applications.

The TPS5904 and TPS5904A are characterized for operation from –40°C to 100°C and each device is supplied

in an 8-pin DIP or in an 8-pin gull-wing surface-mount package (DCS).
