Flyback, Forward and Isolated;

Key Features:• Automatic feed forward compensation• Programmable pulse by pulse current limiting• Automatic symmetry correction in push-pullconfiguration• Enhanced load response characteristics• Parallel operation capability for modular powersystems• Differential current sense amplifier with widecommon mode range• Double pulse suppression• 200mA totem-pole outputs• ± 1% bandgap reference• Under-voltage lockout• Soft-start capability• Shutdown capability• 500KHz operationThe SG1846 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 include inherent pulse-by-pulse current limiting capability, automatic symmetry correction for push-pull converters, and the ability to parallel “power modules” 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 sup-pression, deadtime adjust capability, and a ±1% trimmed bandgap reference.
