Характеристики

UC3846DW, ШИМ-контроллер на токовых переключателях [SOIC-16]The UC3846DW is a current-mode Pulse Width Modulation (PWM) Controller 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 while maintaining equal current sharing. The 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.
