DESCRIPTION

The UC1901 familyis designedto solve manyof the problems associ-
ated with closinga feedback control loop acrossa voltage isolation
boundary. Asa stable and reliable alternativetoan optical coupler, these
devices featurean amplitude modulation system which allowsa loop er-
ror signal to be coupled with a small RF transformer or capacitor.
The programmable, high-frequency oscillator within the UC1901 series
permits the useof smaller, less expensive transformers which can readily builtto meet the isolation requirementsof today's line-operated power
systems. As an alternativeto RF operation, the external clock inputto
these devices allows synchronizationtoa system clockorto the switch-
ing frequency of a SMPS. additional featureisa status monitoring circuit which providesan active-
low output when the sensed error voltageis within ±10%of the reference.
The DRIVERA output, DRIVERB output, and STATUS output are disabled
until the input supply has reacheda sufficient levelto allow proper operation the device.
Since these devices can alsobe usedasa DC driver for optical couplers,
the benefitsof 4.5to 40V supply operation,a 1% accurate reference, anda
high gain general purpose amplifier offer advantages even though an AC
system may notbe desired.
