Description

The TPS5904 and TPS5904A optoisolated feedback amplifiers consist of a precision programmable referenceand 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 inisolated 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 currenttransfer ratio (CTR) ranges from 100% to 400% in the standard version. The TPS5904A version with a150%-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. Thetight-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 suppliedin an 8-pin DIP or in an 8-pin gull-wing surface-mount package (DCS).Typical Application++VIPWMControlVO7TPS5904/A12R16TPS5904: Reference-voltage tolerance, 0.8% CTR Range, 100% to 400%TPS5904A: Reference-voltage tolerance, 0.5% CTR Range, 150% to 300%43R2www.taosinc.comTexas Advanced Optoelectronic Solutions Inc.800 Jupiter Road, Suite 205 S Plano, TX 75074 S (972) 673-0759ttCopyright © 2000, TAOS Inc.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, andfunctional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is notimplied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.NOTES:1.Derate linearly from 25°C at a rate of 2.95 mW/°C.

2.Derate linearly from 25°C at a rate of 1.76 mW/°C.3.Derate linearly from 25°C at a rate of 4.12 mW/°C.

4.Optocoupler total-package flame retardancy is tested to IEC695-2-2 using a flame application time of 30 seconds. Outer mold
