SM645/SM646/SM647  
SWITCHING REGULATOR  
POWER OUTPUT STAGES  
DESCRIPTION  
FEATURES  
The SM645/646/647 series of Power Output Stages are espe-  
cially 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 noise and RFI  
High operating frequency (to > 100KHz) results in  
smaller inductor-capacitor filter and improved power  
supply response time  
High operating efficiency at 7A typical performance -  
Rise and fall time < 300ns  
Efficiency > 85%  
HIGH RELIABILITY FEATURES  
Available with high reliability processing
