The SM625, SM626 and SM627 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. FUNCTIONAL DIAGRAM SM625/SM626/SM627 SWITCHING REGULATOR POWER OUTPUT STAGES |
