[ SYSTEM GENERAL ]
DESCRIPTION
The SG348xG series of current-mode PWM controllers combines high performance
with Green-mode power saving features. SG348xG controllers are fully pin-to-
pin compatible with bipolar UC384x devices, but they have improved features
and functionality. SG384xG series controllers are compatible with the BiCMOS
fabrication process, enabling the use of low start-up current and operating
currents. This feature further improves power conversion efficiency. The
minimal start-up current has been reduced to 5uA, and the minimum operating
current has been reduced to 5mA.
Each SG384xG has a slew rate controlled high current totem pole output,
ideally suited for driving a power MOSFET while keeping EMI low.
