Low Quiescent Current (0.50mA Typ)
UC19432
UC29432
UC39432
UC39432B
DESCRIPTION
The UC39432 is an adjustable precision analog controller with 100mA 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 in-
puts are accessible for custom configuration. A sister device, the UC39431
adjustable shunt regulator, has an on-board resistor network providing six
preprogrammed voltage levels, as well as external programming capability.
