description  
These optoisolated feedback amplifiers consist of the industry standard TLV431 precision programmable  
reference with a 1% reference voltage tolerance, and an optocoupler. The devices are primarily intended for  
use as the error-amplifier/reference/isolation-amplifier element in isolated ac-to-dc power supplies and dc-to-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 TPS5908A and TPS5910A versions with 150%-to-300% CTR are available for  
higher-performance applications. All versions enable power-supply designers to reduce component count and  
save space in tightly packaged designs. The tight-tolerance reference eliminates the need for adjustments in  
many applications.  
These devices are characterized for operation from 40°C to 100°C. Each amplifier is supplied in an 8-pin DIP  
or in an 8-pin gull-wing surface-mount package (DCS).
