data sheet no. pd 10029-g series pvi photovoltaic isolator 5-10 volt output general description the pvi photovoltaic isolator generates an electri- cally isolated dc voltage upon receipt of a dc input signal. the input of the pvi is a light-emitting diode (led) which is optically coupled to, but electrically isolated from, the output. a gaaias led is used for high output and maximum stability. the infrared emis sion from the led energizes, by photovoltaic action, a series connection of silicon pn junctions. a unique alloyed junction stack which is edge-illumi- nated is used to form the output photovoltaic genera- tors. this novel structure produces extremely high operating efficiency. units are available with a single 5-volt output or dual 5-volt outputs which can be series connected to produce 10 volts. a pvi can serve as an isolator, a coupler and as an isolated voltage source. as an isolator, the pvi can serve as the key component in a solid state relay cir- cuits. the pvi is ideally suited for driving power mos- fets and igbts or sensitive gate scrs to form solid state relays. as a coupler, the pvi can sense a low-level dc sig- nal and transmit a voltage signal to an electrically remote circuit. as a voltage source, the pvi can function as a ?dc transformer? by providing an isolated, low-current dc source for biasing or supplying power to low quiescent current electronic devices. conventional optocouplers merely modulate the resistance of an output device such as a transistor, diode or resistor. such optocouplers require a sepa- rate voltage source to detect the presence of an input signal. in contrast, a pvi actually transmits (and transforms) energy across the isolation barrier and directly generates an output voltage. this dc volt- age, available at a 2500vac isolation level, gives cir- cuit designers a new and uniquely useful electronic component. features isolated voltage source mosfet driver up to 10a output fast response gaaias led 2500v (rms) isolation 8-pin dip package single or dual output part identification part number outputs output output voltage current pvi5050 1 5.0v 5a pvi5080 1 5.0v 8a PVI1050 2 5.0/10.0v 10/5a replaced by pvi-n
