SM645/SM646/SM647 SWITCHING REGULATOR POWER OUTPUT STAGES DESCRIPTION Features The SM645/646/647 series of Power Output Stages are especially designed to be driven with standard PWM integrated circuits to form an efficient switching power supply. The SM645, SM646 and SM647 are optimized for non-isolated Buck and Buck-Boost application. The hybrid circuit construction utilizes thick film resistors on a beryllia substrate for maximum thermal conductivity and resultant low thermal impedance. All of the active elements in the hybrid are fully passivated. - Equivalent to the Unitrode PIC 645, 646, 647 - 15A current capability - Cost saving design reduces size, improves efficiency, reduces...
