DESCRIPTION

The SM600/601/602 and SM610/611/612 series of Power Output Stages are especially designed to be driven with standard PWM integrated circuits to form an efficient switching power supply. The SM600, SM601 and SM602 are optimized for non-isolated Buck and Buck-Boost application, where SM610, SM611 and SM612 are best suited for DC-DC Boost type applications as well as negative output Buck Converters. 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.
