The SG1846 family of control ICs provides the required features to implement Fixed Frequency, Current mode control schemes while maintaining a minimum external parts count. The advanced 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 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 suppression, dead-time adjust capability, and a ±1% trimmed bandgap reference.
