DESCRIPTION

The UC19432 is an adjustable precision analog controller with 100-mA sink capability if the ISET pin is

grounded. A resistor between ISET and ground will modify the transconductance while decreasing the maximum

current sink. This will add further control in the optocoupler configuration. The trimmed precision reference along

with the non-inverting error amplifier inputs are accessible for custom configuration. A sister device, the UC19431

adjustable shunt regulator, has an on-board resistor network providing six preprogrammed voltage levels, as well

as exernal programming capability.
