UAC3092
LINEAR INTEGRATED CIRCUIT
ALTERNATOR VOLTAGE
REGULATOR
DESCRIPTION
The UAC3092 is specifically designed for voltage regulation and
Load Response Control (LRC) of diode rectified alternator charging
systems, as commonly found in automotive applications.
In maintaining system voltage, the UAC3092 monitors and
compares the system battery voltage to an externally programmed
set point value and pulse width modulates an N–channel MOSFET
transistor to control the average alternator field current.
