Linifinty / Microsemi SG3846DW Current Mode PWM Controller 1Hz-500kHz 100mA 16-Pin SOIC W SOIC-16

Key Features: • Automatic feed forward compensation • Programmable pulse by pulse current limiting • Automatic symmetry correction in push-pull configuration • Enhanced load response characteristics • Parallel operation capability for modular power systems • Differential current sense amplifier with wide common mode range • Double pulse suppression • 200mA totem-pole outputs • ± 1% bandgap reference • Under-voltage lockout • Soft-start capability • Shutdown capability • 500KHz operation The 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.
