SMPS Controller

The KA3846 control IC 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 improved line regulation, enhanced load response characteristics, and a simpler, easier-to-design control loop. Topological advantages include inherent pulse-by-pulse current limiting capability, Automatic symmetry correction for push-pull converters, and the ability to parallel "power module" while maintaining equal current sharing. Protection circuitry includes built-in-under-voltage lockout and programmable current limit in addition to soft-start capability. A shutdown 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 suppression, deadtime adjust capability, and 2% trimmed bandgap reference. The KA3846 features low outputs in the OFF state.
