FEATURES
Description
Automatic Feed Forward Compensation
The UC1846/7 family of control ICs provides all of the necessary
Programmable Pulse-by-Pulse Current Limiting
Features To Implement Fixed Frequency, Current Mode Control Schemes While Maintaining A Minimum
External Parts Count. The Superior Performance Of This Technique Can Be Measured In Im-
Automatic Symmetry Correction In Push-pull Proved Line Regulation, Enhanced Load Response
characteristics, and
Configuration
a simpler, easier-to-design control loop. Topological advantages in-
Enhanced Load Response Characteristics Clude Inherent Pulse-by-pulse Current Limiting Capability,
automatic symmetry correction for push-pull converters, and the ability to par-
Parallel Operation Capability for Modular Power Systems
Allel "power Modules" While Maintaining Equal Current Sharing. Protection Circuitry Includes
built-in under-voltage lockout and pro-
Differential Current Sense Amplifier with
grammable current limit in addition to soft start capability. A shut-
Wide Common Mode Range
down function is also available which can initiate either a complete
Double Pulse Suppression
shutdown with automatic restart or latch the supply off.
500mA (Peak) Totem-pole Outputs
Features Include Fully Latched Operation, Double Pulse Suppression, Deadline Adjust Capability, And
a 1% trimmed bandgap
