Current Mode PWM Controller

The UC1846 UC1847 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 superior performance of this technique CAN be measured in im- proved line regulation, enhanced load response characteristics, and a simpler, easier-to-design control loop. Topological advantages in- clude inherent pulse-by-pulse current limiting capability, Automatic symmetry correction for push-pull converters, and the ability to par- allel power modules" while maintaining equal current sharing. 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. 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. By Texas Instruments
