Current Mode PWM Controller

FEATURES

DESCRIPTION

•

Automatic Feed Forward Compensation

The UC1846/7 family of control ICs provides all of the necessary

features to implement fixed frequency, current mode control

schemes while maintaining a minimum external parts count. The su-

perior performance of this technique can be measured in improved

line regulation, enhanced load response characteristics, and a sim-

pler, easier-to-design control loop. Topological advantages include

inherent pulse-by-pulse current limiting capability, automatic sym-

metry correction for push-pull converters, and the ability to parallel

“power modules" while maintaining equal current sharing.

Configuration

•

Enhanced Load Response Characteristics

Parallel Operation Capability for Modular

Power Systems

Protection circuitry includes built-in under-voltage lockout and pro-

grammable current limit in addition to soft start capability. A shut-

down function is also available which can initiate either a complete

shutdown with automatic restart or latch the supply off.

•

Differential Current Sense Amplifier with

Wide Common Mode Range

•

Double Pulse Suppression

500mA (Peak) Totem-pole Outputs

±1% Bandgap Reference

Under-voltage Lockout

Soft Start Capability

Other features include fully latched operation, double pulse sup-

pression, deadline adjust capability, and a ±1% trimmed bandgap

reference.

The UC1846 features low outputs in the OFF state, while the

UC1847 features high outputs in the OFF state.
